What is stainless steel flange?
Stainless steel flange is a common pipe connection that is widely used in various industrial fields, including petroleum, chemicals, food processing, pharmaceuticals, etc. As an important part of the pipeline system, stainless steel flanges are responsible for connecting, sealing and supporting pipelines.
Stainless steel flanges consist of two interconnected ring parts that are bolted together. These two ring-shaped parts are called flanges respectively, and there is usually a hole in the middle for connecting pipes. The design and structure of stainless steel flanges can be adjusted according to different needs to adapt to the requirements of different piping systems.
One of the main advantages of stainless steel flanges is their corrosion resistance. Since the stainless steel flange is made of stainless steel material, it has good corrosion resistance and can resist the erosion of various chemical substances. This allows stainless steel flanges to be used in some special environments, such as acid and alkali media or high temperature and high pressure conditions.
