ASTM A105 SCH 80 Carbon Steel Flange

Blind flanges are used to seal the end of piping systems or pressure vessel openings.

ASTM A182 F304 600LB slip on flanges are very popular type of flanges because of the excellent functions and high pressure.ASME B16.47 Series A & B are American Standard for large dimension flanges.According to ASME B16.47 Series A& B,the smallest size of flanges is 22 in.

What is a blind flang,what about its specification and advantage.

SW flange can be used in many applications in piping systems.SW Flanges are forged flanges.Socket weld flange has many classes:150LB, 300LB, 600LB, 900LB, 1500LB, 2500LB.Stainless steel flanges have better functions than other flanges which made from carbon steel or alloy steel.

Stainless steel flange, also called SS flange, it means the material of flange is stainless steel. Common material standards and Grades are ASTM A182 Grade F304/L and F316/L, with pressure ratings from Class 150, 300, 600 etc and to 2500.

What is a WN Flange?and what about its specification

It is used to insert the pipe into the inner hole of flange, as the flange inner diameter is little bigger than the pipe’s outer diameter, pipe and flange could be connected by lap welding at the top and bottom of the flange.

ASME B16.5 SW flange is belong to American Standard for forged flanges,this kind of flange are been used all over the word.Forged flanges are high pressure flanges,the commonly used classes are CL 300,CL 600 for forged flanges.Stainless steel flanges always more expensive than other flanges because of the stainless steel has better functions.

ASME B16.5 forged flanges are high pressure flansges inculding pressures 150LB,300LB,600LB,900LB,1500LB,2500LB.SS316 CL300 flanges is a kind of stainless steel CL300 flanges.Other popular grades of stainless steel are SS316L,SS304/304L.

A182 F316‌ lap joint flange uses flanges, steel rings, etc. to put the flange on the pipe end, so that the flange can move on the pipe end. The steel ring or flange is used as a sealing surface, and the flange is used to press them tightly.

All flanges are round disks with holes for bolts around the rim, but the commonalities end there. a projecting flat rim used for strengthening or attachment.

There are Weld Neck Flange ( WN),Slip-on Flange (SO), Threaded Flange (THD),Socket Weld Flange (SW),Blind Flange (BL),Lap Joint Flange (LAPJ),Plate flange (PL). We also supply alloy steel flanges and stainless steel flanges .

ASTM A182 F316 is a popular grade for stainless steel in American Standard.Stainless steel fittings are popular because of the an-ti corrosive function.Stainless steel pipe fittings can used over 50 years.

Reducing pipe (reducing nipple) is a pipe fitting used for straight-line connection of two pipes with different sizes to realize pipe diameter reduction. There are concentric reducing joints and eccentric reducing joints

600LB SW flanges can socket with the flanges and then welded with the pipes.Large diameter flanges can be series A and series B.ASME B 16.47 A & B are standard for large diameter flanges.

Socket weld flange can socket with the end of pipe,and welding on the pipe.Stainless steel flanges are popular because of the an-ti corrosive function.Stainless steel pipe fittings can used over 50 years.

High pressure flange carbon steel material: ASTM A105 / A105N, ASTM A350 LF2/LF3, ASTM A694 F42 / 46 / 56 / 60 / 65, P235GH, P265GH, P280GH, P355GH

150 LB blind flange is a flange similar to plug.BL flanges are used to close the pipe system.ASTM A105 forged flange is carbon steel flange in American Matel Standard.

ASME B 16.5 2 inch socket weld (SW) flanges are used for small size and high pressure pipe systems.Stainless steel flanges are more expensive than carbon steel flanges because of the better functions.The pressures could be chosen:CL150,CL300,CL600,CL900,CL1500,CL2500.

Socket Weld Flange contain a shoulder on the flange inside that acts as a guide to set the depth at which the pipe is welded to the flange.

Stainless steel flange is popular because stainless steel has great anti-corrosive function.Flanges can be many types:WN,SO,SW,THD,LAPJ,BL.These flanges use different connections to connect with the pipes.Shanghai Zhucheng is a high quality manufactory who can supply all types of flanges.

Steel Pipe Elbow is the most common pipe fitting that changes the direction of the pipeline. It plays a important role in the piping system.

orged steel flange is a disc-shaped piece of equipment used to connect a pipe to fittings or valve or other component to form a pipework system. Usually flange has been attached to pipe or tube end to, and then a gasket is inserted in the middle to form a seal. Finally they are joined together with bolts and nuts.
