What is equal tee Equal tee, means the branch diameter of this tee is same with the main pipe (Run pipe) diameter of this tee. When we see only one size of tee in its description, it means this tee is the equal tee. for example, 6″ Tee mean the tee main pipe and branch pipe both are 6 inches. Sometimes the equal tee also described 6″X 6″ which is the same meaning of 6″ tee.

A Reducing Tee is also called “unequal tee“, which means the tee branch pipe diameter is not same with the run pipe of the tee. Commonly, in a reducing tee, the branch pipe diameter is smaller than the running pipe. But there are also some project the branch pipe diameter of the tee is bigger than the run pipe, it means the branch is the inlet of the flow . Regarding the butt welding steel tees, it should be described the two different diameters to show it completely, for example, 4″X3″ tees. In the pipe fitting application, the reducing tee is used when considering size reduction from one of the run ports to the other. For different industry projects, the reducing tees are available in many various combinations of sizes and configurations in a piping system. Reducing tee is another type of pipe tee used in pipe and tube fittings. Pipe Tees are available two popular forms—have all outlets of the same size or they can be reducing tees in which they are with a combination of different outlet sizes. Reducing tee, like all pipe tees, is in the shape of T with two ends of equal size and the third one slightly smaller. In other words, reducing tee is a type of pipe fitting in which the branch port size is smaller than the ports of the run. This type of pipe fitting can also consider size reduction from one of the run ports to the other. For different applications in various industries, the reducing tees are available in many various combinations of sizes and configurations. Apart from the standard sizes, other unusual combinations of size can also be attained using component parts of tees, reducing tee and reducers. Materials used: Aluminum Bronze Brass Carbon Ceramic Clay Rubber Fiberglass Cast iron Lead Plastic Alloy steel Stainless steel etc. Uses of reducing tees: Reducing tees are used to provide high integrity mechanical connections in various pumping applications. Are widely used for positive pressure and vacuum applications. Used in ultra high purity systems. It features unique machining and surface enhancement which can prevent outgassing and inhibit corrosion. Reducing pipe tees are also used to reduce delivery lines in order to feed icemakers and other applications which require a reducing tee fitting. Reducing tee usually provides smooth flow paths and there is no turbulence or entrapments. Used for waste, water supply. Used for water, drain pipe , gas , oil etc. Applications: Some popular applications of reducing tee are in the field of: Food and Beverage Semiconductor Life Sciences Shipbuilding Chemical Processing Cooling and Refrigeration Water Treatment etc.Product name: reducing teeDetails : Nominal DiameterOutside DiameterCenter to EndD1D2DNNPSSeries ASeries BSeries ASeries BCM15×15×151/2×1/2×1/221.31821.318252515×15×101/2×1/2×3/821.31817.314252515×15×81/2×1/2×1/421.31813.710252520×20×203/4×3/4×3/426.92526.925 29 29 20×20×153/4×3/4×1/2 26.9 25 21.3 18 29 2920×20×103/4×3/4×3/826.92517.314292925×25×251×1×133.73233.732383825×25×201×1×3/433.73226.925383825×25×151×1×1/233.73221.318383832×32×321.1/4×1.1/4×1.1/442.43842.438484832×32×251.1/4×1.1/4×142.43833.732484832×32×201.1/4×1.1/4×3/442.43826.925484832×32×151.1/4×1.1/4×1/242.43821.318484840×40×401.1/2×1.1/2×1.1/248.34548.345575740×40×321.1/2×1.1/2×1.1/448.34542.438575740×40×251.1/2×1.1/2×148.34533.732575740×40×201.1/2×1.1/2×3/448.34526.925575740×40×151.1/2×1.1/2×1/248.34521.3185757

Straight Tees A Straight Tee means a tee of pipe fitting which the branch outlet has a 90 degree direction turning from the main pipe of the tee. Commonly people consider the straight tee as the equal tee, it is a mistake . Equal tee means a same sizes of the branch and main pipe of a tee. Straight tee means it has a side port at right angle to the run. On the contrary to the straight tee, it is the lateral tee. The straight tee could be a equal tee, also could be a reducing pipe tee (unequal tee). Officially a straight tee will be indicated by 3 diameters, namely 3 x 3 x 2 (A x B x C). The A & B measure stands for the Nominal Pipe Size of Run-Pipe, C measure stands for Nominal Pipe Size of Outlet.

Pipe cross is also called cross fitting ,it looks like tee but has four ends. Think about a new branch pass through a equal tee, it is a cross . Commonly, a pipe cross has one inlet end and three outlet ends, sometimes it is three inlet ends and one outlet end. Because of the structure and flowing way of the cross, it is the center of four pipes connection .If there is any change of temperature in the cross point, it will bring a high pressure to the joint the cross. The cross tee has another feature that the products cost is very high, more than two times price to the tees, so it is not used very popular. Types of pipe cross A cross fitting allows four direction transition in pipeline fields. Let us know more about pipe crosss under the following heads: Equal Cross The equal cross is one kind of the pipe cross, just like a equal tee, the equal cross means all the 4 ends of the cross are in same diameter. The pipe cross, like a road cross, is the joint of 4 pipes. Receiving the pressure from the 4 pipes, the weld joint between the pipes and cross must be very strong. The cross can not control the flow direction by its shape, So the four ends of the cross commonly are only one inlet and three outlets, or one outlet and three inlets. Reducing cross/Unequal cross The reducing cross also is called unequal cross , it is the pipe cross which the four branch ends are not in the same diameters.  just like a unequal tee, the reducing cross connect the pipes of different diameters. Since the pipe cross has four ends, when describe a reducing cross people should indicate all the four ends diameters and their positions, or else it may bring som misunderstanding.

There are straight pipe crosss which have the same size openings. Reducing pipe crosss have one opening of different size and two openings of the same size. There are sanitary pipe crosss which are used in waste lines. These kind of pipe crosss have a curved branch which is designed for a clean out plug. They are used to prevent obstruction of waste. A cross pipe cross has four equal sized female openings. A wing pipe cross has lugs to fasten the fitting to a wall or stud. A compression pipe cross uses compression fittings on two or more ends. A test pipe cross has a threaded opening. This opening is used in conjunction with a threaded plug for a clean-out opening on a drain pipe.

Seamless stainless steel elbow is a kind of pipe fitting used in the turning of the pipe. In the pipeline system used in all the pipe fittings, the largest proportion, about 80%. In general, different materials or wall thickness of the elbow will choose different forming processes. At present, the stainless steel seamless elbow manufacturing plant commonly used stainless steel seamless elbow forming process is hot, stamping, extrusion and the like. Hot bend forming process is the special Elbow push processing machine, a core mold and a heating device, which makes in the mold blank in pushing mechanism driven by forward motion and in the movement is heating, expanding diameter and bending forming process. The deformation characteristics of the hot seamless stainless steel elbow is based on the metal plastic deformation before and after constant volume law to determine the tube diameter, the tube diameter less than the diameter of the elbow, the through mandrel control the blank deformation process, the arc by the compression of the metal flow, compensation for expanding and other parts of the thin, in order to get uniform wall thickness of seamless stainless steel elbow. The hot pushing elbow forming process has the advantages of beautiful appearance, uniform thickness and continuous operation, suitable for mass production. Therefore, it becomes the main processing method of alloy steel, carbon steel elbow, and is also used in some specifications of stainless steel elbow forming. In addition to outside the common forming process, stainless steel seamless elbow forming as well as the use of tube billet is extruded to the outside of the die, again through the tube blank pigging plastic forming process. But this process is relatively complicated, and the operation is troublesome, and the forming quality is inferior to that of the preceding process, so it is less used.

Concentric Reducer Concentric reducer is a kind of fitting that be used for reducing piping size. Concentric reducer is most commonly used and often eccentric reducer used in piping in about pump and pipe rack area. Concentric Reducer is used to join pipe or tube sections on the same axis. They provide an in-line conical transition between pressurized pipes of differing diameters. A pipe reducer can be a single diameter change or a multiple diameter change. The pipes cannot recognize what the outside configuration of the pipe reducer looks like. The pipe flow is affected by the inside diameter conical transition configuration which can be axially moved and externally reconfigured to provide for more economical reducer fittings. Thus, concentric reducers connect pipes of unequal size but have a common centerline. In other words, it is a type of pipe fitting with different size ends to join pipes of different diameter that joins pipe sections on the same axis. Concentric reducers are designed with the small and large diameters on opposite ends and joined by a cone shaped transition section. They are available in both seamless and welded construction. How to take measurements of concentric reducers? Get the measurements of outer diameter (OD) and inner diameter (ID) , height (H), and the total dimension (T1, T2). Uses of concentric reducers: Some uses of concentric reducers are as follows: 1. Concentric reducers will transition gracefully between the piping and the pump. 2. The concentric reducers help in transporting slurries or abrasive liquids. 3. They are useful in services where cavitation is present. 4. When transporting between flanges or pipes of different ratings and wear protection is necessary, concentric reducers are ideal. 5. Concentric reducers are used in discharge of the pump.

Eccentrice Reducer Eccentrice reducer is a kind of fitting that be used for reducing piping size. Eccentrice reducer is most commonly used and often eccentric reducer used in piping in about pump and pipe rack area. An eccentric reducer is manufactured with the smaller outlet off center to the larger end, which allows it to align with only one side of the inlet. The reducer must be installed with straight side up so that it can prevent trapping air at the pump suction. The eccentric pipe reducers allow simple connection of different sized pipes. Uses of eccentric reducers: 1. Keeping big pipes and small pipes together. 2. Reducing noise and vibration at the same time. 3. Requires less installation space. 4. Absorbs pipe wall and fluid borne noise. 5. Less turbulence or material entrapment. 6. Eccentric reducers are used with flat side up in pump suction to avoid cavitation.

I believe that when many people hear the word “pipe cap” for the first time will be tiny one leng. What is the pipe cap? What did it look like? What is the use? But for the mechanical workers this pipe cap is more common than the. In fact, the pipe cap is also called plug, head, pipe cap, bulkhead, the name of good let people understand. The pipe fittings are welded on the pipe end or are arranged on the outer thread of the pipe end to cover the pipe. Used to close the pipeline, the same role with the pipe blocking the same. Blind in the form of a close, but the blind is blocked can be removed, and the welded pipe cap is not removable. The pipe cap includes the design of convex pipe cap, cone shell, reducer, flat cover and tight mouth. The convex pipe cap includes a hemispherical, oval disc pipe cap, pipe cap and spherical pipe cap. From the stress angle convex pipe cap from the hemispherical pipe cap is not good, but from look on the manufacturing difficulty, has good manufacturing. And pipe cap from the use of classified material generally can be pided into several common copper pipe cap, iron pipe, stainless steel pipe cap, plastic pipe cap, pipe cap! The pipe cap on the market are very much, because the industry is also very much, at present in many petrochemical, nuclear power, machinery, medical equipment, chemical fertilizer, shipbuilding, waterproofing treatment, pipe, water heating, solar water heaters and other industry need use to pipe cap! pipe cap according to the classification of the pressure for about seventeen, and American Standard pipe pressure rating is the same, sch5s, sch10s, sch10, sch20, sch30, sch40s, STD, sch40, sch60, sch80s, XS; sch80, SCH100, sch120, sch140, sch160, XXS. The most commonly used is two kinds of STD and XS. pipe cap in the construction industry not very common, necessary pipe cap just in the end of the pipe for closed pipeline, and the blind plate uses basically the same is blind plate installed can be disassembled, but pipe cap can not disassembled, pipe cap is welded on the top of the pipe, and the blind plate in the form of very close to. Above is the pipe cap of general use, actually a little attention point can see pipe cap can be pided into many types, so can not be generalized and pipe cap with the head on the literal meaning almost, in fact distinguish is not small: head for devices to a container under the (vertical) equipment part or left and right ends (horizontal) pipe cap are generally outside diameter, pipe caps can be screwed directly in the pipe, does not need other pipe fittings. So use pipe cap introduced today is here.

Where to buy flange You can go to the website: www.wilsonpipeline.com to buy flange. wilsonpipeline Pipe Industry Co., Limited (www.wilsonpipeline.com) offers a wide range of flanges, pipe flanges, tube flanges,based on guaranteed quality. Common production as world standards include ASA/ANSI (USA), PN/DIN/EN (European), BS10 (British/Australian), BS4504 (British/Australian) and JIS (Japanese). wilsonpipeline’s flanges are made by forging or casting according to clients’ request. Further, the industrial flanges in each standard are pided into pressure classes, allowing flanges to be capable of taking different pressure ratings. These pressure classes also have differing pressure and temperature ratings for different materials. wilsonpipeline’s flange faces are also made to standardized dimensions and are typically flat face (FF), raised face (RF) or ring joint (RJT) styles.  Flange designs are available as weld neck flange (WN), slip-on flange (SO), lap joint flange (LJ), socket weld flange (SO), threaded / screwed flange (TH), blind flange (BL), plate flange (PL), orifice flange, orifice plate, spectacle blind, spectacle flange, blind spacer and also blank. A flange is a method of connecting pipes, valves, pumps and other equipment to form a piping system. It also provides easy access for cleaning, inspection or modification. Flanges are usually welded or screwed. Flanged joints are made by bolting together two flanges with a gasket between them to provide a seal. Materials for Flanges Pipe flanges are manufactured in all the different materials like stainless steel, cast iron, aluminium, brass, bronze, plastic etc. but the most used material is forged carbon steel and have machined surfaces. In addition, flanges, like fittings and pipes, for specific purposes sometimes internally equipped with layers of materials of a completely different quality as the flanges themselves, which are “lined flanges”. The material of a flange, is basically set during the choice of the pipe, in most cases, a flange is of the same material as the pipe. All flanges, discussed on this website fall under the ASME en ASTM standards, unless otherwise indicated. ASME B16.5 describes dimensions, dimensional tolerances etc. and ASTM the different material qualities. Dimensions of Flanges Each flange according to ASME B16.5 has a number of standard dimensions. If a draftsman in Japan or a work preparer in Canada or a pipefitter in Australia is speaking about a Welding Neck flange NPS 6, Class 150, Schedule 40 ASME B16.5, then it goes over the flange which in the image here below is shown. If the flange is ordered, the supplier want to know the material quality. For example ASTM A105 is a forged carbon steel flange, while A182 is a forged stainless steel flange. Measure the size of a flange At some point, with all the possibilities of thread form, diameter, and pitch, you need to send it off to SK Grimes or another machinist. You could buy the thread pitch gauges and comparator and thread micrometer (to measure minor diameter) to fully define the thread, but that still won’t help you to find a ring. Pressure Classes of Flanges The concept of flange ratings likes clearly. A Class 300 flange can handle more pressure than a Class 150 flange, because a Class 300 flange are constructed with more metal and can withstand more pressure. However, there are a number of factors that can impact the pressure capability of a flange. The Pressure Class or Rating for flanges will be given in pounds. Different names are used to indicate a Pressure Class. Flange Forging Process Understanding customers requirement and ensuring to supply as per these requirements is realised with the help of quality assurance at Sunny Steel one of the best Flange Manufacturers in China , our product range include all types of flanges such as MS Flange ( Mild Steel ) , Raised face flange , Weld neck flange, Bellow Flange , and Flanges according to custom requirement. In addition, we also can produce the DIN flange, and the forgings according to the customers drawings, for example, rings and shafts. Types of Flanges The most used flange types in Petro and chemical industry are: Welding Neck Flange Slip On Flange Socket Weld Flange Lap Joint Flange Threaded Flange Blind Flange Special Flanges Except the most used standard flanges, there are still a number of special flanges such as: Orifice Flanges Long Welding Neck Flanges Weldoflange / Nipoflange Expander Flange Reducing Flange Stainless Steel Flanges We Offer Stainless Steel Parts Stainless Steel machined parts turned Parts Cast Parts Stainless Steel Forged Parts Stainless Steel Fittings SS Stainless Steel Fitting Stainless Steel Fittings Stainless Steel Components facility up to 40 kg’s in weight and Stainless Steel castings up to 1meter in length. Forged Flange, Forged steel flanges Forged flange is defined as a plate type device, normally round, that is attached to the end of a pipe, fitting, valve or other object to facilitate the assembly and disassembly of a piping system. Forged steel flanges made of carbon steel or stainless steel, the materials conform to the JIS, ASTM A182,A105, DIN17100 ST-2 and BS standard. Blind Flange The blind flange is used to close ends of piping systems. It is a kind of round plate with no center hold but with all the proper bolt holes. This flange helps in easy access to a line once it has been sealed. The blind flange is sometimes custom made or machined to accept a nominal sized pipe to which reduction is being made. This reduction can be a threaded reduction or welded reduction. Figure-8 Blanks A figure-8 blank (also called a Spectacle Blind Flange) is a pressure-retaining plate with one solid end and one open end connected with a web or tie bar. A spectacle flange is a specialty flange made of two metal discs attached in the middle by a small section of steel. Spectable flanges get their name because they look like a pair of reading glasses, or spectacles. Spectacle flanges, also known as spectacle blind flanges, are most commonly used on piping systems that need to be separated regularly or where the flow through the systems is regularly stopped. One end of the spectacle flange is solid, while the other end has a hole in the center. The spectacle flange can be rotated to place either the solid or hollow end within the pipe system, thereby opening or closing the flow. Lap Joint Flange The lap joint flange is practically identical to a slip-on flange except it has a radius at the intersection of the bore and flange face. This radius is necessary to have the flange accommodate a lap joint stub end. Normally, a lap joint flange and a lap joint stub end are mated together is an assembly system. Orifice Flanges Orifice flanges are used instead of the standard pipe flanges when orifice plate or flow nozzle is used. The basic purpose for this is to measuring the flow rate of either gases or liquids in the respective pipeline. These flanges are used in various industrial applications and are available in various sizes and materials. Reducing Flanges A reducing flange consists of a flange with one specified diameter having a bore of a different and smaller, diameter. Except for the bore and hub dimensions, the flange will have dimensions of the larger pipe size. Designed for use in changing diameters in a piping system. A reducing flange consists of a flange with one specified diameter having a bore of a different and smaller, diameter RTJ Flanges, Ring Type Joint Flange Ring Type Joint Flange is a method of ensuring leak proof flange connection at high pressures. A metal ring is compressed into a hexagonal groove on the face of the flange to make the seal. This jointing method can be employed on Weld Neck, Slip-on and Blind Flange. Socket Welding Flanges, SW Flange The socket welding flange is similar to a slip-on flange except it has a bore and a counterbore dimension. The counterbore is slightly larger than the O.D. of the matching pipe, allowing the pipe to be inserted into the flange similar to a slip-on flange. Slip On Flange, SO Flange The Slip on flange has a low hub because the pipe slips into the flange prior to welding. It is welded both inside and out to provide suffcient strength and prevent leakage.Slip-on flanges are all bored slightly larger than the O.D. of the pipe. Threaded Flanges, TH Flanges Threaded (Screwed) flange is similar to the Slip-On flange, but the bore is threaded. Its chief merit is that it can be assembled withour welding, explaining its use in low pressure services at ordinary atmospheric temperatures, and in highly explosive areas where welding create a hazard. Welding Neck Flanges The Welding neck flanges is normally referred to as the high hub flange. It is designed to transfer stresses to the pipe, thereby reducing high stress concentrations at the base of the flange. The welding neck flange is the best designed butt-welded flange of those currently available becuase of its inherent structural value. It is expensive because of the design. Long Weld Neck Flanges Tube OD sizes: 3/8 to 2 inches Materials: Flange: 304 or 316L stainless steel O-rings: Viton, Buna, & silicone Fasteners: Wingnut, SureSeal, bulkhead & EVAC clamps Vacuum range Elastomer seal: >=1 x 10^-8 Torr – High vacuum EVAC metal seal: >=1 x 10^-11 Torr – UHV Temperature range Viton: -20°C to 200°C Silicone: -50°C to 230°C Buna: -30°C to 110°C EVAC metal seal: -270°C to 150°C Applications of flanges Flanges are integral parts of many engineering and plumbing projects. In many applications, engineers need to find a way to close off a chamber or cylinder in a very secure fashion, usually because the substance inside must differ from the substance outside in composition or pressure. Below are our available industrial pipe flanges that will meet your project needs.
