Product Description
Duplex Steel S31803 Slip On Flanges are flanges made from duplex stainless steel grade S31803, also known as 2205 stainless steel. These flanges are used in various piping systems and are designed to slip over the end of a pipe and be welded in place. They are widely used in industries such as oil and gas, petrochemical, chemical, and offshore applications due to their excellent corrosion resistance, high strength, and good weldability.
Some key features of Wusheng Duplex Steel S31803 Slip On Flanges:
Duplex stainless steel: S31803 is a duplex stainless steel, which means it has a microstructure consisting of both austenite and ferrite phases. This provides it with superior mechanical properties, including higher strength and better resistance to stress corrosion cracking compared to traditional austenitic stainless steels.
Wusheng Duplex Steel S31803 Slip On Flanges can be easily slipped over the end of a pipe and then welded in place. This makes them convenient to install and suitable for applications where the flanges need to be frequently disassembled.
Corrosion resistance: Duplex Steel S31803 Slip On Flanges offer excellent corrosion resistance, particularly in aggressive environments such as chloride-containing solutions. They are resistant to pitting, crevice corrosion, and general corrosion, making them suitable for use in corrosive media.
High strength: Duplex stainless steels, including S31803, have higher strength compared to austenitic stainless steels, which makes them suitable for high-pressure and high-temperature applications.
Good weldability: Duplex Steel S31803 Slip On Flanges can be easily welded using common welding techniques such as TIG (Tungsten Inert Gas) and MIG (Metal Inert Gas) welding. They do not require pre-weld or post-weld heat treatment, making them convenient to fabricate and install.
