ASTM A312 TP316L Stainless Steel Welded Pipe

ASTM A312 TP316L is the standard specification for seamless, welded, and heavily cold-worked austenitic stainless steel pipes. It specifically covers welded pipes intended for general corrosive environments and low-temperature/high-temperature applications.

 

The TP316L stainless steel industrial pipes supplied by GNEE are designed for transporting low-pressure liquids and gases, particularly in environments with a risk of sensitization. They can withstand high temperatures up to 1000–1200°C and are suitable for elevated-temperature applications. Due to their larger diameter, these pipes have a relatively smaller installation footprint, facilitating easier assembly and installation.

 

Our TP316L large-diameter stainless steel welded pipes can be customized with diameters ranging from φ150 to φ4500 (circular pipes) and wall thicknesses of 3–60 mm. The pipe surfaces can be treated with inner/outer polishing, sandblasting, shot blasting, seamless finishing, or passivation.
