Plain Flange (Plate flange) is also called flat flange, plate slip on flange or a ring flange. It looks like a flat circular disk with inner bore and bolt holes on it . It is one kind of the slip on flange.Plate flange means the flange is like a flat plate, it could be Raised Face (RF) sealing face , commonly the plate flange could be RF or FF face, the Raised Face Plain Flange is much popular in regular industry systems.In ANSI/ASME B16.5 flange standard , there is no plate slip on flange , only hub slip on flange in it , but in different projects the ANSI B16.5 plate flange is used a lot for decrease the cost of the projects. The ANSI /ASME B16.5 plain flange should have the same dimensions and PCDs with the Slip on flange, the only difference is without a hub on the flange.
Welding Neck WN Flange are designed to be joined to a piping system by butt welding. This kind of flange include lots of specification, Weld neck Flange is expensive because of its long neck and cost of people for contact WN flange with pipeline or fitting, but is preferred for high stress applications. The necks, or hubs, transmits stresses to the pipeline. The gradual transition of thickness from the base of the hub to the wall thickness at the butt weld provides important reinforcement of the Weld Neck flange. The bore of Weld - Neck flange matches bore of the pipeline, reducing turbulence and erosion.
Flat faced flange is a flange that is machined flat and does not have a ridge like a raised face or ring type joint flange. The flat surface allows for the gasket to have full contact with the entire mating surface. The purpose of the flat face is to eliminate the bending moment put on the flange when the bolts are torqued. When using cast iron or fiberglass flanges, this bending moment can easily break the flange.In general, flat faced flanges are used in low pressure and temperature environments such as water treatment or pump suction flanges. Flat face flanges are usually common when the piping or piping components are brittle such as plastic, fiberglass or cast iron. However, it should be noted that these flanges come in all different types of materials, including steel.
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 blind flange is available in various sizes and materials and is used to provide positive closer on the ends of pipes, valves or equipment nozzles. 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.
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 sufficient strength and prevent leakage.Slip-on flanges are all bored slightly larger than the O.D.of the matching pipe.They are preferred over welding neck flanges by many users due to their lower initial cost,but final installation cost is probably not much less than that of the welding neck flange because of the additional welding involved. We are a professional flange manufacturer with 30 years history and the standards we can produce is ANSI flange, DIN flanges, BS flanges and EN1092-1 flange. Our brand is TANA and we do best for our products.
An elbow is a pipe fitting installed between two lengths of pipe or tubing to allow a change of direction, usually a 90° or 45° angle, though 22.5° elbows are also made. The ends may be machined for butt welding, threaded (usually female), or socket, etc. When the two ends differ in size, the fitting is called a reducing elbow or reducer elbow.
Stub Ends are fittings used in place of welded flanges where rotating back up flanges are desired. They are also called Lap Joints and Vanstone Flared Laps. A rotating back up flange seats itself against the back surface of the Stub End. When bolts are added, the clamping action of the bolts presses the rotating back up flange against the back of the Stub End. The gasket surface of the Stub End then presses against a gasket and another gasket surface providing joints like standard flange joints. The seal is made by the gasket surface of the stub end alone, the flange only provides the clamping pressure on the joint.
Rubber Expansion joint, Rubber Flexible Joint, Rubber bellow 1. The joint could primarily reduce the vibration and the noise of the piping system. Completely solve the different piping problems as dispalcement of joint, axial flex and etc. 2. According to different material requirment, product could be made as acid proof, alkali proof, corrosion proof to suit different medium and Environment 3. The material are good sealing, light weighting, easy to fix and maintain, also has long working expecting. But please keep far away from sharp matal in order to avoid breaking of the rubber body. The material are good sealing ,light weighting,easy to fix and maintain,also has long working expecting.. But please keep the rubber expansion joint far away from sharp metal in order to avoid breaking of the rubber body.
The TANA expansion joints portfolio basically consists of three main series:Standard series: expansion joints up to DN 150 (6"), Industrial series: expansion joints up to DN 1.000 (40"), Special series: expansion joints >DN 1.000 The heart of all expansion joints is the metal bellows. Thanks to modern design and manufacturing facilities, all TANA expansion joints offer the following advantages:High flexibility, Short build length,Large movement capacity, Durability and excellent chemical resistance.
The metal spirally-wound gasket adopts high-quality SUS304 or SUS316 ("V" or "W"shape) metal strips, other alloy materials and some flexible materials like graphite, asbestos, PTE and non-asbestos, which are overlapped and wound spirally with each other. The metal strips are fixed on the initial and terminal ends by means of spot welding. The metal spirally-wound gasket has the best resilien ce among the semi-metal hermetic gaskets. Its structural density can be made subject to different locking forces. Also the internal and external steel rings can be used to control its maximum compaction. It's not demanding for the surface precision of the flange sealing surface contacting the spirally-wound gasket. It's especially applicable for such occasions as uneven load, slack joint, periodical changes of temperature and pressure, impact or vibration. It's an ideal static seal element for flange connection in valves, pumps, heat exchangers, towers, manholes,handholes and so on.
A reducer is the component in a pipeline that reduces the pipe size from a larger to a smaller bore (inner diameter). A reducer can be used either as nozzle or as diffuse depending on the mach number of the flow. A reducer allows for a change in pipe size to meet hydraulic flow requirements of the system, or to adapt to existing piping of a different size. Reducers are usually concentric but eccentric reducers are used when required to maintain the same top-or bottom-of-pipe level.
Pipe cap is usually used for protecting the end of pipe and other fittings,so the shape is designed according to the shape of pipe line. We also use caps to cut off the transition and the connection treat can be butt weld,socket weld and thread connection according to use requirements. TANA Steel are Manufacturer, Exporter and Supplier of Pipe Cap. Pipe caps are widely well-known for the utmost output and outstanding results that it gives. Pipe Cap manufactured using superior grade raw materials. Pipe Cap are used for connecting pipes of different diameters and find wide applications in various chemicals, construction industries, paper, cement & ship builders.
A tee is also called triplet,three way and "T" pieces and it can be used to either combine or split a fluid flow. Most common are tees with the same inlet and outlet sizes, but 'reducing' tees are available as well. it means the one or two ends are differ in dimension.due to thisdimension differ,the makes the tee fittings with the capacity to control the volume when requried.
PTFE gasket has strong corrosion resistance and friction-resistance,By adding filler such as glass fiber,carbon fiber,copper powder,graphite,asbestos,MOS2,AL2O3,carbon powder,ceramic fiber,metal powder,polyamide,PS,the hardness,compression strength and abrasion resistance of the products is improved ,in addition,it will have good heat conductivity and low heat expansion coefficient.
