ASTM A270 TP316L 卫生级不锈钢管在制造过程中应注意以下几点：
1) ASTM A270 TP316L Seamless steel pipe should not contains any kind of welding processing.
2) ASTM A270 TP316L 焊接钢管适用于自动焊接加工，但不得使用金属材料作为填充物。
3) ASTM A270 TP316L 高冷加工（HCW）管应在最终退火前通过冷加工将管壁和焊缝的厚度减薄不少于 35%，制成焊管。应注意在焊接过程中添加填充材料。焊缝应按照 ASME 锅炉和压力容器标准规范进行 100% 射线图形检查。
4) ASTM A270 TP316L 卫生管可根据制造商的要求提供热加工或冷加工。
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.
