Bangdong Supply Forged Weld Neck Flange,Forged Slip On Flange,Stainless Steel Plate Flange.Socket Welding Flanges The socked welding flange if 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. The diameter of the smaller bore is the same as the I.D. of the matching pipe. A restriction is built into the bottom of the bore which sets as a shoulder for the pipe to rest on. This eliminates any restriction in flow when using a socket welding flange

LAP JOINT FLANGES are primarily employed with lap joint stubs, the combined initial cost of the two items being approximately one-third higher than that of comparable welding neck flanges. Their pressure-holding ability is little, if any, better than that of slip-on flanges and the fatigue life of the assembly is only one-tenth that of welding neck flanges.

The chief use of lap joint flanges in carbon or low alloy steel piping systems is in services necessitating frequent dismantling for inspection and cleaning and where the ability to swivel flanges and to align bolt holes materially simplifies the erection of large diameter or unusually stiff piping. Their use at points where severe bending stress occurs should be avoided.

THREADED FLANGES are confined to special applications. Their chief merit lies in the fact that they can be assembled without welding this explains their use in extremely high pressure services, particularly at or near atmospheric temperature, where alloy steel is essential for strength and where the necessary post weld heat treatment is impractical. Threaded flanges are unsuited for conditions involving temperature or bending stresses of any magnitude, particularly under cyclic conditions, where leakage through the threads may occur in relatively few cycles of heating or stress; sea welding is sometimes employed to overcome this, but cannot be considered as entirely satisfactory.

Long Welneck Flanges
The LWN is FVC's basic standard flanged connection. This seamless product offers a nominal bore as well as a heavy wall thickness making it ideal for highly corrosive applications.

Forged flange is the best mechanical properties of a flange product, its raw materials are generally tube, and then after cutting and then continue to beat, to eliminate the ingot in the segregation, loose and other defects. Price and mechanical properties are higher than ordinary casting flange a grade. The flange is a part that connects the pipe with the pipe and the valve, is connected to the pipe end. It is also used for the flange on the equipment inlet and outlet.
The connection between the two devices is the part connecting the pipe to the pipe. At the end of the tube. Is a subsidiary of the pipeline accessories products. Forging flange The main materials are carbon steel, alloy steel, stainless steel. The main criteria are GB, superscript, American Standard, German standard, the Japanese standard and so on.
The main anti-corrosion treatment is oil and galvanized. Forging flange pressure, temperature performance is better, generally applicable to high pressure and high temperature working environment.

Forged flange applications
Forged flanges are used as a connection component for pipes, valves, pumps and other equipment to form a pipework system. They provide easy access for cleaning, inspection, modification or repairs.
Flanges are usually welded onto pipes or screwed onto a threaded pipe end and then joined with bolts to make the connection.

Bangdong Supply Astm A234 WPB Steel Elbow,Carbon Steel Thread Coupling, A234 WPB Carbon Steel Coupling.A Lap Joint Flange is used in conjunction with a stub end where the flange is slipped over the stub end fitting which is then connected to either to pipe or another fitting by welding or other mechanical means.

The flange itself is not fixed and is left loose for proper alignment with the connection it is matching to. The benefits of this assembly is if there is frequent or rapid disassembly and assembly during maintenance of the piping system. The ability to spin and position the flange compensates for any misalignment of the bolt holes during reassembly.
