Flange, also known as flange or flange, is an important part used for the connection between pipes, which is connected to both ends of the pipe. The two flanges can also be connected to each other, because there are holes in the flange, and bolts can be used to make the two flanges closely connected. But different material flange function is not the same, the following small series to take you to understand the difference between stainless steel flange and high pressure stainless steel flange.

There are many kinds of stainless steel flange, including plate flat welding flange, neck flat welding flange, neck butt welding flange, threaded flange, socket welding flange, loose flange, blind flange and various non-standard flange, which are collectively referred to as stainless steel flange. The difference between stainless steel flange and high pressure stainless steel flange lies in the word "high pressure". High pressure flange can withstand relatively high pressure. The flange commonly used in 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 shall not have any cracks.

Like the general flat welding flange, the pressure can reach 40 kg, while the pressure of high pressure flange can reach 2500 LB ~ 3000 lb, or even higher. The above is the difference between ordinary stainless steel flange and high pressure flange.
