4.To be equality and mutual benefit 

1.   Socket welding flange/SW flange/flange manufacurer,  We are a operation 20 years of flange manufacturer ,that's the best proof of our product and service quality.

2.   The socket welding flange is similar to a slip-on flange expect it has a bore and a counter bore dimension. The counter bore 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 bore which sets as a shoulder for the pipe to rest on. This eliminates any restriction in flow when using a socket welding flange  

3.Win-Win cooperation is our aim of operation, we desire cooperation not just business only.

4.Forging technics ensure our flange can bear high pressure and more durability
