Tube and shell heat exchanger is chemical, oil refining, food, light industry, energy, pharmaceutical machinery and many other widely used universal equipment. With the development of the industry, in energy storage, conversion, waste heat recovery, using new energy heat exchange equipment, is widely used in pollution control. Recently, the zhejiang wilsonpipeline industry co., Limited for American customers in the production of a batch of high quality stainless steel tube and shell heat exchanger parts. The tube and shell heat exchanger parts as shown in the image. The shell and tube heat exchanger parts are as follows: 1. 904L Floating tube sheet 2. 904L Fixed tube sheet 3. 904L Support plate/baffle 4. 904L Center baffles 5. 904L Baffle 6. 316L WNRF stainless steel flange 1 7. 316L WNRF stainless steel flange 2 8. 316L WNRF stainless steel flange 3 9. Floating head stainless steel flange 10. Floating split stainless steel flange 11. 904L Heat Exchanger Bundle Tubes 904L Baffles: 904L Baffles serve three functions: 1) Support the 904l seamless tubes; 2) Maintain the tube spacing; 3) Direct the flow of fluid in the desired pattern through the shell side. 904l seamless tubes: 904l seamless tubes diameters are 25.4 mm. 904l seamless tubes wall thickness ranges is 12 BWG. 904l seamless tubes are tubing with special surface to enhance heat transfer on either or both sides of the tube wall. 904L Tube Sheets: 904L Tube Sheets are plates or forgings drilled to provide holes through which tubes are inserted.  Tubes are appropriately secured to the tube sheet so that the fluid on the shell side is prevented from mixing with the fluid on the tube side. The distance between the centers of the tube hole is called the tube pitch; normally the tube pitch is 1.25 times the outside diameter of the tubes.  Other tube pitches are frequently used to reduce the shell side pressure drop and to control the velocity of the shell side fluid as it flows across the tube bundle. wilsonpipeline pipe industry sends all the tube and shell heat exchanger parts to the customer, the final assembly into a tube and shell heat exchanger by the customer. Products passed the customer’s test and inspection, won the customer high praise. wilsonpipeline Pipe Industry Co., Limited is a leading manufacturer and supplier of nickel alloy and stainless steel products, including Super Duplex Stainless Steel Flanges, Stainless Steel Flanges, Stainless Steel Pipe Fittings, Stainless Steel Pipe. wilsonpipeline products are widely used in Shipbuilding, Nuclear power, Marine engineering, Petroleum, Chemical, Mining, Sewage treatment, Natural gas and Pressure vessels and other industries.

Tee is usually used in construction, electricity, shipbuilding, chemical industry, etc. Different types of tee pipe fitting has its own disadvantages and advantages. Tee pipe fittings have different characteristics of different types, to understand their respective characteristics and the insufficiency, can make better use of tee pipe fittings. Pipeline of tee in the mechanical tee, groove reducing tee, groove mechanical tee, ordinary tee. There are two kinds of reducing tee styles: groove type, thread type: the groove used another three clamp, screw type with two other band. There are two kinds of mechanical tee styles: groove type, screw type. The groove to the other with a clamp, screw-type don’t need. There are two kinds of normal tee styles: groove type, screw type. The groove to the other with three clamp, screw type with two other band. Mechanical tee is itself with clamp, need the kind of open hole in the pipe. Screw-type reducing tee is to separate a small tube is threaded, and head is still the clamp.

wilsonpipeline Pipe Industry Co., Limited (www.wilsonpipeline.com) is specialized in the production of flange gasket, flange manufacturer, quality, service and thoughtful. The new sealing method in the plate flange is more important to ensure that the joint is not leaking. The reason for the reduction of the size of the compact flange, the latest development of Vector company by the new flange to overcome the shortcomings of the ANSI flange. Compact flange has many advantages: the specification of the flange space, weight loss. Because the sealing of the diameter is reduced, the sealing surface is reduced. Second, the sealing ring has replaced the flange gasket, to ensure the matching between the sealing surface. Thus, a very small pressure can be pressed close to the cover. The need to reduce the pressure, the final design of a small volume and light weight (than the traditional ANSI flange weight loss 70%80% new products. The American National Institute of national standards for design of ANSI flange has provided a suitable sealing technology for the oil and gas industry, for decades. And fruitful. However, the demand for oil and gas industry has changed, and the defects of the ANSI flange are often revealed. The maintenance benefit interest principle, the environment and the best guarantee of health and safety is the 21st century operators and contractors are facing three major issues. Therefore, people began to consider new flange sealing method. ANSI flange sealing principle is extremely simple: the two sealing surface of the bolt flange gasket and seal each other. But this also leads to the destruction of the seal. In order to keep the seal, we have to maintain a huge bolt force. To do this, the bolts must be done even more. And greater bolt must match the larger nut. This means that larger diameter bolts need to create conditions for the nut is tightened. As everyone knows, the greater the diameter of the bolt, the application of the flange will become bent, the only way is to increase the flange part of the wall thickness. The whole device will require a great deal of size and weight, which is a special issue in the offshore environment, because in this case, the weight is always the main problem that people need to pay attention. And, fundamentally speaking, the ANSI flange is an invalid seal, the need to load the 50% bolts for the extrusion of the gasket, while the load is used to maintain the pressure only 50%. Where can we find the high quality flange gasket: sealing ring.You can visit this website: www.wilsonpipeline.com (wilsonpipeline Pipe Industry Co., Limited).

wilsonpipeline Pipe Industry Co., Limited (www.wilsonpipeline.com) is a professional production of various kinds of super duplex stainless steel flange, stainless steel flange, duplex stainless steel flange, alloy flange, all kinds of pipes and pipe fittings professional manufacturers, the company has advanced production equipment and perfect testing tools. Raised face flange (RF), female and male flange (M/FM), RTJ flange. For toxic medium, as long as it’s not extreme harm level, stress level is less than or equal to 1.6 MPa, usually can use surface RF flange, 2.5 MPa began generally require the use of concave and convex surface of the pipe flange. For extremely dangerous medium, need to use the concave and convex surface of the pipe flange. Female and male pipe flange is commonly used in the German standard and national standard of PN4.0, PN6.4 MPa grade, mainly determined by the stress level, female and male pipe flange sealing surface is better than RF flange, but not easy to replace the gasket. The usage of grooved surface pipe flange with concave and convex surface are basically the same. RTJ flange is mainly used in high temperature and high pressure, or both high condition. In the American standard pipe flange, commonly used in Class 600 lb (part), 900 lb, 1500 lb, 2500 lb classes. In Germany standard flange and is commonly used in national standard flange in PNl0.0, PN16.0, PN25.0, PN32.0, PN42.0 MPa in the pipe flange. The sealing gasket is used stainless steel ring. General toxic and harmful medium, are not recommended to choose the ordinary plane flange and the RF flange, should choose or concave and convex surface is better than the sealing performance of the pipe flange.
