316L Stainless Steel Welded Square Piping/ Tubo soldado de acero inoxidable
Application: A large number of stainless steel pipe are used to transport fluid, such as oil, natural gas, water, gas, steam, etc. in addition, when bending and torsion resistance are the same, the weight is relatively light, so it is also widely used in the manufacture of mechanical parts and engineering structures.
Main Standard: ASTM A312, ASTM A269, ASTM A249, ASTM A554
Main Grade: 316L; 1.4404
Outer Diameter: 5*5—150*150mm
Wall Thickness: 0.4-6mm

Advantages Of Welded Tubes & Pipes
A. Lower cost compared to the equivalent seamless alternative
B. Short lead time
C. Better surface finishing of outside and inside, the internal material surface for welded tubes can be checked prior to manufacture
D. Thinner wall thickness and more uniform
E. Tighter tolerance
