STAINLESS STEEL PIPES 316 manufacturer
The 316/316L alloy contains higher percentages of molybdenum and nickel than 304 stainless pipe, increasing the corrosion resistance and making it an ideal material for applications in aggressive environments. 316 / 316L stainless steel pipe is used for applications that require the high strength, toughness and workability, coupled with increased corrosion resistance. Stainless Steel 316/316L Structural applications include handrails, poles and support pipe for salt water and corrosive environments .The alloy contains higher percentages of molybdenum and nickel than 304 stainless pipe, increasing the corrosion resistance and making it an ideal material for applications in aggressive environments.

APPLICATIONS

316 / 316L seamless pipe is used for pressure operations to move liquids or gases in water treatment, waste treatment, petrochemical, chemical and pharmaceutical industries. It is not used as often as welded pipe due to its reduced weldability compared to 304 stainless unless its superior corrosion resistance outweighs it decreased weldability.
