Annealing
All tubing shall be furnished in the heat-treated condition, Hydrogen bright annealed in line to 1900°F(1040° C) minimum and rapidly quenched.

 

Hot-treatment methods for ASTM A270 TP316L stainless tube
All materials should supply after hot-treatment. Except the for duplex stainless steel materials S31803, S32003, S320205, S32750, N08926 and N08367, in these cases it shall consist of heating the material to a minimum temperature of 1900 ℉ (1040 ℃) and quenching in water or rapid cooling by other means.

 

ASTM A270 TP316L Sanitary Tubing Surface Requirements
Surface of rolled products: No need extra polishing or smooth treatment.
Mechanical polished surface: Purchasers according the same numbering abrasive (grinding stuff) to polish the products get the required products' surface.
Electrolytic polishing of the surface: Before this processing, manufacturer could use other ways to polish products.
The maximum average of roughness: Customers could specify the maximum roughness of internal surface, external surface and both surface.
Normally surface treatment: Internal, External, SF4, SF3, etc.

 

Packaging
To ensure sanitary standards, our tubing is packaged using protective sleeving, capped with air-tight plastic end caps. The tubing is then placed in thick cardboard cores and capped securely on each end for maximum protection during shipment. Large quantities will be shipped securely in wood or metal crates.
