ASTM A358 CL1 TP316L Stainless Steel Welded Pipe For High Temperature Service

ASTM A358: "ASTM" stands for the American Society for Testing and Materials, which sets standards for a wide range of materials and products. A358 specifically addresses electric fusion welded (EFW) stainless steel pipe for corrosive or high-temperature applications.

ASTM A358 CL1 TP316L stainless steel welded pipe is an EFW pipe made from austenitic stainless steel (Grade 316L). Its low carbon content enhances weldability and corrosion resistance, making it particularly suitable for chloride environments. CL1 refers to the Class 1 designation in the A358 standard. Class 1 covers pipes that are duplex welded using a full penetration welding process. These welded pipes are capable of withstanding higher internal pressures. TP316L, a low-carbon version of TP316 stainless steel, offers enhanced corrosion resistance, especially in environments with sensitization potential, such as welding applications. As Class 1 pipe conforming to the ASTM A358 standard, all welds are duplex welded with filler metal and undergo comprehensive radiographic inspection.
