ASTM A312 TP321 Stainless Steel Bright Annealed Seamless Pipe for Oil Industry

Corrosion Resistance: TP321 contains titanium, which stabilizes the structure and effectively resists intergranular corrosion caused by high temperatures during oil exploration, refining, and transportation. It can withstand the erosion of various oilfield media such as crude oil, natural gas, and produced water.
High - Temperature Performance: In high - temperature sections of oil refining processes like distillation columns and heaters, it maintains good mechanical properties, ensuring stable operation under elevated temperatures without significant deformation or performance degradation.
Bright Annealing Advantage: The bright - annealed surface has good smoothness, reducing the adhesion of oil impurities, facilitating cleaning, and minimizing the risk of fouling - related corrosion, which helps maintain the internal cleanliness of the pipeline and the efficiency of oil flow.
Seamless Structure Reliability: The seamless design avoids potential leakage points at welds, providing a more reliable pipeline system for the transportation of high - pressure and high - value oil products, enhancing safety and reducing the risk of environmental pollution.
