Whenever installing flanges, either cast flanges (part of pipes) or ring flanges (slid onto to pipes), always make sure the line’s pressure will carry.  •  Cast Flange Cast flanges are part of the line section and are aligned to connect quickly to another flanged section. These flanges are strong and resistant to pressure. The disadvantage to a cast flange is if flange must be disassembled or replaced the entire length of line must also. •  Ring Flange Ring flanges are separate parts from the line. The line has a flared end and the flange rings around the flared end to seal it tight when connected to another flange. The advantage is the ring flange allows for different diameters of line to attach using the flange as a reducer. The flange is also easily replaceable without replacing the entire section, an important quality with caustic and corrosive media. The disadvantage is the ring flange/flare connection may not be as resistant to high-pressure media in the line. •  Gaskets Flange installation uses gasket material placed between each flange connection. Different gaskets are needed for containing and handling different media. In most instances if a leak or failure occurs at the flange-to-flange fitting, the gasket can be considered the prime source for the malfunction. Replacing gaskets connected to either type of fitting involves the same procedure and does not necessarily involve replacing the flanges or the line. •  Installation Installing flanges is a basic mechanical job: insert the gasket material, align the flange bolt holes and secures with the necessary number of bolts. Always bolt every hole. Don’t assume leaving one or two disconnected will satisfactory seal the connection. Also, use a criss-cross pattern to tightening the bolts: tighten the bolt on top then the one at the bottom, to the left and then the right. Repeat this around the flange’s circumference. This bolting procedure will apply pressure to the gasket and the facing flanges evenly and result in a complete seal. Just bolting around the circle can lead to crimping and poor alignment of the last remaining bolts. •  Fastener Always use fasteners specified for the flange fitting. Using fasteners made of the wrong material, As an example, galvanized bolts with stainless steel flanges can lead to galvanic corrosion. Using bolts too small for the flange can allow the flange to move. Bolts too short may lead to insufficient threading and the flanges will not be secure.

Butt Weld Fittings: Reducers Reducers be applied, to change from pipe diameter in one direction. Standard there are 2 possibilities, the concentric reducer, is usually used in vertical pipe lines, and the eccentric reducer that is used in horizontal pipe lines. TF & BF On an isometric view, in a horizontal line, with a eccentric reducer must be declared, or the flat side at the bottom or top must be assembled. Perhaps, you have ever seen on a drawing, the abbreviation “TF” or “BF”. This stands for respective “top flat” and “bottom flat” LENGTH OF  REDUCERS The length of a Reducer is very short in relation to the diameter, so in some dimensions the transition from one to another diameter is very abruptly. For example, a reducer 6″ x 2½” has a length of 140 mm. On this short distance a pipeline will be reduced from 168.3 mm O.D. to 73 mm O.D. During the design phase of a new pipe system, a piping designer certainly must think about it. An alternative for a smoother flow would be to apply multiple reducers like: 6″ x 5″ (L=140 mm) 5″ x 4″ (L=127 mm) 4″ x 3½” (L=102 mm) 3½” x 3″ (L=102 mm) 3″ x 2½” (L=102 mm) So, now the distance is approximately 573 mm if the 6″ pipe is reduced to 2½” inches, and and a smoother flow is guaranteed. In practice this example will probably never occur, I hope, no no, I′m sure, there are better designers like me. For example: Bottom flat eccentric reducer is often be used in pipe racks to keep the pipeline at the same elevation, after a pipe size change. When a concentric or a flat on top eccentric reducer in a pipe rack will be used, the support detail, probably change. Top flat eccentric reducer are often be used in pump suction lines to avoid accumulation of gas pockets.Eccentric reducers can avoid small “dead spots” that exist behind concentric reducers. Some draughtsmen also specify the size difference T between the center lines. As a eccentric reducer in a vertical line is used, it may also be important, which side should be oriented to the north, south, east or west. Dimensions and dimensional tolerances of welding reducers Reducers are mainly used as part of pipelines in the construction, energy engineering and mining industry. Dimensions of tube reducers are: outside diameter of 26.9 -114, 3 mm, wall thickness from 2.3 to 3.6 mm, NPS 3/4 – 4 Steel for butt welding reducers Reducers are made from carbon and low alloy steels, dimensional tolerances are in accordance with relevant standards. Heat treatment, condition of delivery and surface The input tubes used for production of reducers are heat treated. Reductions are delivered with the inner and outer surface descaled not preserved, without surface protection or with surface treated by blasting. Ends customization of the reducers Upon agreement it is possible to supply reducers with a wall thickness of more than 3 mm with adjustment for a weld according to DIN 2559 standard. Testing of weld reducers The input tubes and ready made reducers are tested according to requirements and the appropriate standards. Marking of the weld reducers Reducers are marked as required by standards or agreement. Marking is done usually by stamping the agreed data. Packaging of weld reducers Reducers are packaged in cardboard boxes or metal pallets. Certificates for weld reducers Certificates are issued according to either DIN 50049 or EN 10204 standards.

Socket Weld Pipe Fittings are unthreaded, but has large sockets at both ends to accept a pipe end. The fitting is then permanently welded to the pipe. Socket weld connections fuse the fitting to the pipe, and are typically used for high-pressure pipe systems. A 90-degree socket-weld elbow can be specified in a number of sizes. • Nominal Pipe Sizes Class 3000 (Schedule 80) socket-weld elbows can be specified for pipe sizes ranging from 1/4 inch to 4 inches in diameter. The higher-pressure Class 6000 (Schedule 160) elbows are manufactured in sizes ranging from 3/8 inch to 4 inches. • Socket and Bore Diameters The socket diameter is the outside width of the socket; the bore diameter is the size of the opening through which the pipe must pass. Socket diameters can be specified in sizes ranging from .42 to 4.545 inches; bore diameters range from .269 to 4.026 inches. Dimension do not vary from Class 3000 to Class 6000 fittings. • Minimum Instillation Space Requirement The amount of clearance that must be allowed for an elbow differs by the size of the fitting and the service class. For instance, a 3/8-inch Class 3000 elbow must be installed in a space 1.1 inches in diameter, whereas a 3/8-inch Class 6000 elbow must be installed in a 1.3-inch space. • Distance to Inside Corner Another important specification for socket weld elbows is the distance from the outer edge of the socket bore to the point where the interior of the fitting bends. This distance can range from .08 inch in a 1/8-inch Class 3000 fitting, to 4.2 inches in a 4-inch fitting. The same distance in Class 6000 fittings is somewhat larger. For instance, a 4-inch fitting in this class measures 4.5 inches from edge of collar to interior bend.

Pipeline all position automatic welding refers to the relatively fixed in the pipe, welding pipe car drive the welding torch along the orbit around the tube wall motion, so as to realize the automatic welding. Generally speaking, the whole position automatic welding device is composed of welding pipe trolley, running track, automatic control system and so on. The purpose of developing a fully automatic welding equipment is to improve the welding quality and productivity, to reduce the labor intensity of workers. Welding pipe trolley Welding pipe car is to realize automatic welding process of the driving mechanism, which is installed in the welding track, with a torch along the pipe wall of the circular motion, it is one of an important link of the pipe automatic welding. Welding pipe trolley should have the characteristics of beautiful appearance, small size, light weight, convenient operation and so on. The core part of it is walking wire mechanism and welding torch swing mechanism, regulating mechanism of feeding. Walking mechanism is composed of a motor and a gear transmission mechanism and the walking motor execution of the computer control unit sends the position and velocity command, the motor should be with speed feedback mechanism, in order to ensure the motor in pipeline girth seam of each location accurate positioning, but also has better speed tracking function. The wire feeding mechanism must ensure that the wire feeding speed is stable and accurate, with a small moment of inertia, a better dynamic performance, and at the same time, should have sufficient driving torque. And welding torch swing adjusting mechanism should have the torch relative weld left and right swing, left and right end of the stay, up, down, left and right attitude controllable torch angle can be adjusted. Welding pipe of the various parts of the car, the computer can be programmed to achieve automatic control, after the program started, the welding pipeline car parts in accordance with the procedures of the logical sequence of coordination. In the process of welding, the welding parameters can be automatically adjusted according to the amount of the intervention, and the welding parameters can be adjusted according to the amount of the intervention. Welding track Rail is clamped in pipe for welding pipeline trolley walking and positioning of a special mechanism, its structure directly affects the welding pipe car walking stability and positional accuracy, also affects the welding quality. The rail shall satisfy the following conditions: convenient installation and disassembly, easy positioning, reasonable structure, light weight, strength and hardness, wear resistance and corrosion resistance. Orbit is pided into two kinds of flexible track and rigid track. The so-called rigid track is that the body of the track is larger, not easy to deformation, and the flexible track is relatively rigid track. Two types of tracks each have their own characteristics. Rigid track positioning accurate and clamping deformation small, can ensure welding pipe car running smoothly, welding torch radial adjustment is small, but the weight of large, demolition is not convenient. The flexible rail is easy to install and remove, the weight is light, and the precision is not high. Wire feeding mode The smooth degree of wire feed directly affects the welding quality. Wire feeding method can be pided into two types of wire drawing and wire drawing. Wire drawing welding gun from send silk machine installation location is near, welding wire fittings left to send silk machine after being subjected to the smaller resistance. Therefore, it can guarantee wire feeding process is stable, but sent wire machine and wire set shall be installed in the pipeline welding car above and increases welding pipe car weight, to manual assembly disassembly increases the difficulty, increase the weight but also easy to cause pipeline welding trolley is not smooth. Diameter of 0.8 mm or 1.0 mm small wire (weighing about 5 kg) reduced the welding pipe car weight and load, and the welding process is easy to control, but the welding efficiency has certain influence.

When we talk about pipe fittings, it means that pipe fittings are used to connect two or more pipes in two ways—either by threads or by welding. While metal pipes are threaded,  a threaded pipe has screw-threaded ends for assembly or they screw together to connect. For pipe threads sizes, “½–14 NPT” identifies a pipe thread with a nominal inside diameter of ½ inch and 14 threads to the inch and these threads are made according to the NPT standard. The pipe has a left hand thread if “LH” is added. The pipe thread standards followed in US are: NPT: American Standard Pipe Taper Thread NPSC: American Standard Straight Coupling Pipe Thread NPTR: American Standard Taper Railing Pipe Thread NPSM: American Standard Straight Mechanical Pipe Thread NPSL: American Standard Straight Locknut Pipe Thread The word “taper” mentioned above refers to the difference between many pipe threads and those on bolts and screws. Pipe threads not only a make mechanical joint but also a leak proof one. To do this, the threads become shallower the farther they are from the end of the fitting or the pipe. The bottoms of the threads taper. The taper is 1/16 inch in an inch. Because of the taper, a pipe can only screw into a pipe fitting a little distance before it jams. The standard represents this distance, the effective thread. The standard also represents another distance, the engagement, which is the distance the pipe can be screwed in by hand, without much effort. For workers, it is more easy to know how many turns to make by hand or with a wrench.  Types of pipe threads Various threads available in pipe and pipe fittings are as follows: Right-handed or Left-handed Threads Nearly all threads are oriented so that a bolt or nut or any fitting can be tightened. By turning it in a clockwise direction, the item turned moves away from the viewer. And it is loosened by turning anticlockwise when the item moves towards the viewer . This is known as a right-handed thread. Left-handed threads are oriented in the opposite direction. There are also self-tapping screw threads where no nut or bolt is required. Male Threads In male threads, the threads of the pipe are on the outside. Here, tapered pipe threads like NPT, BSPT etc. are used sealing without gaskets. Female Threads In female threads, the threads are on the inside. Here too, like male threads, tapered pipe threads are used for sealing. Male Straight Thread Pipe threads like UNC, UNF, ASME, etc form Male Straight Thread. Female Straight Thread Straight pipe threads like UNC, UNF, ASME, etc. Plain End This is used to connect or insert into the bell end of the connecting pipe. Bell / Socket / Flare This represents the end length of increased diameter into which a pipe end can be fitted. Flange Flanges are used to connect fitting, via bolting or welding. There are basically two types of flanges, circular and square. Compression Fitting This represents compression nut and ferrule to connect to a mating pipe. Pipe Clamp End It is so designed so as to attached to run on pipe or other fitting. Barb / Rib This represents fitting ends to connect only non-rigid pipe or hose. It is sometimes used with a clamped end. Groove This refers to the installation of a coupling feature like an o-ring or elastomeric seal.

Threaded Fittings general Threaded joints probably represent the oldest method of joining piping systems. Like Socket Weld fittings, threaded fittings are mainly used for small pipe diameters (Small Bore Piping); generally for piping whose nominal diameter is NPS 2 or smaller. The dimensional standards for taper pipe threads are given in ASME B1.20.1. That document gives all required dimensions including number of threads per inch, pitch diameter, and normal engagement lengths for all pipe diameters. Threaded piping is commonly used in low-cost, noncritical applications such as domestic water, fire protection, and industrial cooling water systems. Threaded fittings are normally made of cast gray or malleable iron, cast brass or bronze, or forged alloy and carbon steel. They are available in three pressure ratings: Class 2000, 3000 and 6000. NPT Thread All threaded fittings on this page are described, are provided with NPT thread, ASME B1.20.1. The wilsonpipeline Pipe Thread Tapered, is the best known and most widely used connection where the pipe thread provides both the mechanical joint and the hydraulic seal.

They may be used up through Class 6000 Advantages and Disadvantages of Threaded Fittings Advantages Installation productivity is moderately high, and specialized installation skill requirements are not extensive. Leakage integrity is good for low-pressure, low-temperature installations where vibration is not encountered. Disadvantages Rapid temperature changes may lead to leaks due to differential thermal expansion between the pipe and fittings. Vibration can result in fatigue failures of screwed pipe joints due to the high stress intensification effects caused by the sharp notches at the base of the threads. In hazardous piping systems threaded connections should be avoided, if possible. Their vulnerability to fatigue damage is significant, especially where exposed threads are subject to corrosion.

Types of Threaded fittings Threaded fittings are mainly used for small pipe diameters (Small Bore Piping); generally for piping whose nominal diameter is NPS 2 or smaller. 1. Threaded cap( end cap) Threaded cap Seals the threaded end of pipe 2. Threaded half-coupling The threaded half coupling can be directly welded to the run pipe, to make a branch connection 3.

It is a screwed joint design and it consists of three interconnected pieces: two internally threads and a centerpiece that draws the ends together when rotated.

Flanges Gerenal: 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. A typical flange connection: Pipe flanges are manufactured in all the different materials. Some flanges are made of cast and ductile iron, but the most used material is forged carbon steel and have machined surfaces. • TYPES OF FLANGES The most used flange types in Petro and chemical industry are: 1. Welding Neck Flange 2. Slip On Flange 3. Socket Weld Flange 4. Lap Joint Flange 5. Threaded Flange 6. Blind Flange (All types except the Lap Joint flange are provided with a raised flange face.) Most common used flange types 1. Orifice Flanges 2. Spectacle Blinds (part of flange connection) 3. Spades and Ring Spacers (part of flange connection) 4. Long Welding Neck Flanges 5. Weldoflange / Nipoflange 6. Expander Flange 7. Reducing Flange •  MATERIAL FOR FLANGES The most common materials used in flanges  produced is carbon steel, stainless steel, cast iron, aluminium, brass, bronze, plastic et cetera. In addition, flanges, like fitting  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 et cetera and ASTM the different material qualities. • EXAMPLE OF WELDING NECK FLANGE 6″-150#-S40 Each flange according to ASME B16.5 has a number of standard dimensions. If a draftsman in Japan or the work preparer in Canada or a pipefitter in Australia is speaking about aWelding Neck flange 6″-150#-S40 according to 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. So, in a correct order to a supplier two standards must be specified: Welding Neck flange 6″-150#-S40-ASME B16.5 / ASTM A105

Spectacle Blinds are generally applied to permanently separating pipe systems, or just to connect with each other. Spectacle Blinds be applied in systems, which regularly need to be separated from other installations. Normally, a Spectacle Blind is mounted in the “open” position so that flow through the pipe is possible. If the Spectacle Blind in the “close” position is rotated, the pipe is blanked off and no flow is possible. Maintenance on a pipe system can be a reason to rotate the spectacle blind in the “close” position. This run will take place through the hole, that is drilled in the connection piece. By loosening of all bolts, and partial removal of their, the Spectacle Blind can be rotated. After replacing the gaskets (new gaskets are to recommend), the bolts can be re-assembled and tightened.
