Before this processing, manufacturer could use other ways to polish products. A chemical analysis of either one length of flat-rolled stock or one tube shall be made for each heat. ASTM A 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.
Filler materials shall be noted added during welding process.
Electrolytic polishing of the surface: Welded tubes shall be made using an automated welding process with no addition of filler metal during the welding process. In case specified in the order, intergranular corrosion tests shall be performed by manufacturer on specimens representative of the as-shipped atsm.
This specification covers tubes in sizes up to and including 12 in. In case the ASTM A stainless steel pipe for pharmaceutical quality applications, it is more strict on the chemicals, strengths and size tolerances. Historical Version s – view previous versions of standard.
The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Each tube shall be subjected to mechanical tests like reverse flattening test, hydrostatic test or nondestructive electric test.
ASTM A270 Sanitary (Hygienic) Stainless Steel Tubing and Pipe
All material shall be furnished in the heat-treated condition. Wall thickness tolerance shall not vary more than All material shall be furnished in the heat-treated condition. The following surface finishes may be specified: A chemical analysis of either one length of flat-rolled stock or one tube shall be made for each heat.
Octal is located in China recognized as a leading supplier, distributor, and manufacturer union in providing piping solutions for oil and gas company.
The maximum average of roughness: Seamless tubes shall be manufactured by a process that does not involve welding at any stage. Pharmaceutical quality may be requested, as a supplementary requirement. Longitudinally polished finish shall be performed on the inside surface only while a circumferential polished finish shall be done on either the inside surface, outside surface, or both.
ASTM A sanitary tubing intended applied in the diary and food industry, bio processing equipment, and having special surface finish. Combining values from the two systems may result in non-conformance with the standard. These ASTM A austenitic stainless steel sanitary tubing intended for use in the dairy and food industry and having special surface finishes.

Customers could specify the maximum roughness of internal surface, external surface and both surface. Optional supplementary requirements are provided, and when one or more of these are desired, each shall be so stated in the order.
All materials should supply after hot-treatment. Pharmaceutical quality may be requested, as a supplementary requirement.
ASTM A Sanitary (hygienic) Stainless Steel Tube/Pipe Specification
ASTM A tubing using inch-pound as the standard unit of measure. We stocks a wide range of industry standard sizes of both welded and seamless stainless steel pipes.
Surface of rolled products: Sanitary stainless steel pipe and tube shall be capable of passing corrosion tests in the as-shipped condition. All materials should supply after hot-treatment. This abstract is a brief summary of the referenced standard.
