What is the SS flange?
Stainless steel flange is a common pipeline connector, which is widely used in various industrial fields, including petroleum, chemical, food processing, pharmaceutical and so on. As an important part of the piping system, stainless steel flanges take on the function of connecting, sealing and supporting the pipeline. Stainless steel flanges consist of two interconnected ring-shaped parts that are bolted together. Each of these two ring-shaped parts is known as a flange, and they usually have a hole in the center for connecting pipes. The design and structure of stainless steel flanges can be adapted to suit the requirements of different piping systems.
