ASTM A270 TP316L sanitary stainless steel pipe shall be noted below points during manufacturing processes:
1) ASTM A270 TP316L Seamless steel pipe should not contains any kind of welding processing.
2) ASTM A270 TP316L Welded steel pipe applied in automatic welding processing， but should not use metal materials as filler.
3) ASTM A270 TP316L Heavily cold worked (HCW) tubes shall be manufactured by cold working of not less than 35% reduction of thickness of both wall and weld to a welded pipe prior to the final anneal. Filler materials shall be noted added during welding process. The weld shall be 100% radio graphically inspected in accordance with ASME boiler and pressure vessel standards specification.
4) ASTM A270 TP316L Sanitary pipe could be furnished with hot finished or cold finished at Manufacture’s option.
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.
