The difference between stainless steel flange and high pressure stainless steel

　　Flange is mainly used for the connection between the pipe and an important part of the pipe, connected to both ends of the pipe. The two flanges can also be connected with each other, because there are holes in the flange, the two flanges can be closely connected by bolts. But different materials flange have different flange functions.

　　The difference between stainless steel flange and high pressure stainless steel flange lies in the word "high pressure". High pressure flange can bear high pressure. The flange used in common high-pressure pipeline is butt welding flange with neck and integral steel flange. The requirements of this kind of high-pressure flange are quite strict. Solid solution and flaw detection must be done, especially the flange neck must not have any cracks.

　　Like ANSI B16.5 Stainless Steel Forged FF Blind Flange, the pressure can reach 40 kg, while the pressure of high-pressure flange can reach 2500lb ~ 3000lb, or even higher. The above is the difference between ordinary stainless steel flange and high-pressure flange.
