ASME B16.5 forged flanges are flanges manufactured according to American Standard.Stainless steel SS316 CL300 flanges are very popular all over the word beacuse of the superior functions.

ASME B16.5 Standard inculding WN,SO,SW,THD,LAPJ,BL types of flanges.Customers could choose the flanges based on their demand.Flanges can be divided into forged carbon steel flange and forged stainless steel flange according to the material.

 

High Pressure Flanges:Weld Neck (WN) Flanges,Socket Wedl (SO) Flanges

A weld neck flange (also named as high-hub flange or tapered hub flange) is the most common type of flange. Weld Neck Flange is easy to recognize at the long tapered hub, that goes gradually over to the wall thickness from a pipe or fitting.

Slip on flange,always known as SO flange. SO flanges slip over pipes and are designed to bit slightly bigger on the inside than the pipe. They connect to the pipe through a fillet weld at the flange top and bottom. 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.

 

Stainless Steel VS Galvanized Steel

Stainless steel and galvanized steel are both used in corrosive environments.As stainless steel is expensive,many customers choose galvanized steel in equivalent.
