A stainless steel threaded flange is a type of flange that has threads on the inside diameter (ID) of the flange. It is typically used to connect two pipes or fittings together and is screwed onto the end of one of the pipes or fittings. The other end of the pipe or fitting is then screwed into the threaded portion of the flange.
Stainless steel threaded flanges are commonly used in industries such as oil and gas, 石化, and chemical processing. They are able to withstand high pressure and temperature applications, making them a reliable choice for connecting pipes and fittings in these industries. Stainless steel threaded flanges are typically made from materials such as ASTM A182 and ASTM A312, which provide excellent corrosion resistance and durability. They can also be ordered in various sizes and pressure classes to meet specific application requirements.
