ASTM A312 TP316L Stainless Steel Seamless Pipe for Petrochemical Refinery

ASTM A312 TP316L seamless steel pipe is a hollow cross-section seamless steel pipe made of 316L stainless steel, belonging to the austenitic stainless steel series. It is specifically designed for the petrochemical industry and is suitable for transporting fluids and solid materials in the oil, gas, and chemical sectors.

GNEE is a supplier of ASTM A312 TP316L stainless steel pipe, offering both seamless and welded specifications. The pipe is primarily in round cross-section, with sizes ranging from SCH 5 to SCH 160 and XXS. Compared to standard 316 stainless steel, ASTM A312 TP316L round pipe has a lower carbon content (≤0.03%), thus enhancing its corrosion resistance, especially in chloride-containing environments (such as seawater and chemical feedstocks). Its maximum operating temperature can reach 500°C, and it is widely used in petrochemical equipment (reactors, storage tanks), natural gas processing units, and refinery pipelines, capable of withstanding the chemical corrosion of internal media and external temperature fluctuations.

At GNEE, you can purchase seamless steel pipes in various shapes, including rectangular, hydraulic, square, and round. We also provide the necessary testing and certification, and our products are packaged in a variety of ways, including wooden crates and plastic packaging.
