ASTM A270 Sanitary (Hygienic) Stainless Steel Tubing and Pipe

ASTM A270 sanitary (hygienic) stainless steel tubing is the standard specification for the welded seamless, and heavily cold worked welded austenitic and ferritic stainless steel sanitary tubing. It includes the stainless steel tube types in seamless and welded ERW, EFW. ASTM A270 sanitary tubing intended applied in the diary and food industry, bio processing equipment, and having special surface finish.

Stainless tube manufacturing processes
ASTM A270 sanitary stainless steel pipe shall be noted below points during manufacturing processes:

1) Seamless steel pipe should not contains any kind of welding processing.
2) Welded steel pipe applied in automatic welding processing, but should not use metal materials as filler.
3) 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) Sanitary pipe could be furnished with hot finished or cold finished at Manufacture's option.

Hot-treatment methods for ASTM A270 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.

Markes
At last, the mark should furnished in accordance with A 1016/A1016M, and specified in the order. Includes the sanitary stainless steel pipe manufactured in Seamless (SML), Welded (WLD) or heavily cold worked (HCW).

Package
Before delivery, all steel pipes should bundled well, and covered by paper, cloths. Or packed in box by manufacturer.

Addition Requirements
In case specified in the order, intergranular corrosion tests shall be performed by manufacturer on specimens representative of the as-shipped condition. Sanitary stainless steel pipe and tube shall be capable of passing corrosion tests in the as-shipped condition. For austenite alloy steel should meets the Practice E of the standard A262 , and for duplex alloy steels (S31803, S32205 and A32750) should meets experiment C of Test Methods A 923.
In case the ASTM A270 stainless steel pipe for pharmaceutical quality applications, it is more strict on the chemicals, strengths and size tolerances.

Surface Requirements

Surface of rolled products: No need extra polishing or smooth treatment.
Mill Finish— A finish without additional polishing oroperations intended to smooth the surface.
Mechanical polished surface: Purchasers according the same numbering abrasive (grinding stuff)  to polish the products get the required products' Surface:
Finish No. 80 – A ground finish produced by polishing a tube with an abrasive media impregnated with No. 80 grit.

Finish No. 180 – No. 180 grit.
Finish No. 240 – No. 240 grit.
Other mechanically polished finishes may beagreed upon between the purchaser and manufacturer
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.
Surface furnishment also could be decided by manufacturer or purchaser.
Normally surface treatment: Internal, External, SF4, SF3, etc.
