SandvikSAF3207HD bidirectional stainless steel pipe

Product Description: The tensile strength of this material is 980-1180MPa, and the maximum working temperature can reach 90 ℃. Compared to the standard ultra duplex stainless steel SAF2507 previously developed by the company, it has greatly improved in both tensile strength and maximum working temperature. The tensile strength of SAF2507 is 800-1100MPa, and it can work in environments with a maximum water temperature of 65 ℃. SandvikSAF3207HD is specially designed for use in deep water, high temperatures, and extremely high pressures.

Application field: Pipelines for harsh underwater environments

Stainless steel pipes have superior hygiene performance
In fields such as food, pharmaceuticals, and healthcare, there is a high requirement for the cleanliness and sterility of pipeline media. Stainless steel seamless pipes have no obvious welding marks, and their surface smoothness and hygiene performance are very good. Therefore, during the flow process of industrial products, there is no secondary pollution, making them particularly suitable for production and use that require high hygiene conditions.

Coal mine gas drainage: Stainless steel reinforced spiral welded pipes are used for underground gas pipelines in coal mines, solving the problems of anti-static and flame retardant, and extending the service life of pipelines.
