ASTM A312 TP 316/316L ERW Pipes

ASTM A312 TP 316/316L ERW Pipes are premium molybdenum-bearing stainless steel welded pipes designed for highly corrosive and high-temperature environments. These pipes offer superior resistance to chlorides, acids, and marine conditions, making them ideal for chemical processing, marine engineering, pharmaceutical, and offshore applications.

Grade 316 provides enhanced corrosion resistance compared to 304, especially in chloride environments, while 316L (low carbon version) minimizes carbide precipitation during welding, ensuring excellent weldability and long-term structural integrity.
