ASTM A312 TP316L Stainless Steel Seamless Pipe for Petrochemical
ASTM A312 TP316L seamless pipe is a hollow section seamless steel tube made from 316L stainless steel, a member of the austenitic stainless steel family. Designed specifically for the petrochemical industry, it is suitable for conveying fluids and solids in the oil, gas, and chemical industries.
GNEE's ASTM A312 TP316L stainless steel pipe is produced using a seamless forming process, resulting in a predominantly circular cross-section. This maximizes conveying efficiency while ensuring uniform stress distribution within a given circumference. Compared to standard 316 stainless steel, ASTM A312 TP316L round pipe has a lower carbon content (≤0.03%), enhancing its corrosion resistance. With a maximum operating temperature of 500°C, it is widely used in petrochemical equipment (reactors, storage tanks), natural gas processing units, and refinery pipelines, where it can withstand chemical corrosion from internal media and external temperature fluctuations.
