MANUFACTURING PROCESS. TUBES ARE MADE FROM FLAT-ROLLED STAINLESS STEEL BY AUTOMATIC WELDING PROCESS WITHOUT THE ADDITION OF FILLER METAL.

Pipes is commonly used in applications where a high resistance to corrosion, a low maintenance cost and versatility form part of the set requirements.

Austenitic stainless steel have a very wide range of applications, e.g. in the chemical industry and the food processing industry.

Packaging Details:
1. In baling
2. Woven bag packing
3. Put in wooden cases
4. Waterproof cloth packing

Welded Austenitic Stainless Steel Pipes'application: sanitary tubing in the dairy and food industry, and having special surface finishes

specification: Welded pipes: OD6-2032, wall thickness: 1-50mm.
certificate: ISO 9001: 2000 certify by BV, PED &AD certify by TUV.

Packing: plywood boxes or plastic bundles
Shipment: By sea with FCL/LCL contianer or in bulk ;by airfreight,
Standard: ASTM A312

Purpose
(1) reduce the hardness and improve the cutting process.
(2) elimination of residual stresses, stable dimensions, reduced deformation

316/316L stainless steel advantages:
Because there has Mo in it,so the corrosion resistance is very especially the pitting resistance.
