Introduction of Stainless steel pipe for industrial fluid transportation:

Stainless steel pipe for industrial fluid transportation is a high temperature and high pressure heat resistant carbon low alloy steel pipe, can be used in thermal equipment, machinery industry, petroleum geological exploration, containers, chemical industry and special purposes. Because the working environment is mostly under the action of high temperature, high pressure and water vapor, oxidation and corrosion are easy to occur, which requires the product to have high durable strength, high oxidation corrosion resistance, and good organizational stability.
