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.

Alloy 317 flange is an austenitic chromium-nickel stainless steel with excellent corrosion resistance.The high molybdenum content of ASME SA182 SS 317 flange enhances the grade's excellent resistance to pitting. It is the most corrosion resistant of the 300 series alloys and has the highest tensile and creep strength properties at elevated temperatures.
