These ASTM A austenitic stainless steel sanitary tubing intended for use in the dairy and food industry and having special surface finishes. Historical Version s – view previous versions of standard. No filler shall be used in making the weld.
Before this processing, manufacturer could use other ways to polish products. Surface of rolled products: Welded asm shall be made using an automated welding process with no addition of filler metal during the welding z270.
The maximum average of roughness: Or packed in box by manufacturer. Surface of rolled products: All materials should supply after hot-treatment. ASTM A sanitary stainless steel pipe shall be noted below points during manufacturing processes:.
Pharmaceutical quality may be requested, as a supplementary requirement. ASTM A tubing using inch-pound as the standard unit of measure. No filler shall be used in making the weld.
ASTM A tubing using inch-pound as the standard unit of measure. Combining values from the two systems may result in non-conformance with the standard. This abstract is a brief summary of the referenced standard. 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 does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
Each tube shall be subjected to mechanical tests like reverse flattening test, hydrostatic test or nondestructive electric test. The following surface finishes may be specified: In case the ASTM A stainless steel pipe for pharmaceutical quality applications, it is more strict on the chemicals, strengths and size tolerances. ASTM A Sanitary stainless steel tubing specification 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.
ASTM A sanitary tubing intended applied in the diary and food industry, bio processing equipment, and having special surface finish.
ASTM A Sanitary (hygienic) Stainless Steel Tube/Pipe Specification
All material shall be furnished in the heat-treated condition. Before this processing, manufacturer could use other ways to polish products.

Octal is located in China recognized as a leading supplier, distributor, and manufacturer union in providing piping solutions for oil and gas company. All material shall be furnished in the heat-treated condition. Seamless tubes shall be manufactured by a process that does not involve welding at any stage.
Methods of detecting intergranular corrosion for the magnetization coefficient.
ASTM A270 Standard for Stainless Steel Sanitary Tubing
The maximum average of roughness: No need extra polishing or smooth treatment. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Ksi MPa a207, Min. Electrolytic polishing of the surface: Electrolytic polishing of the surface: The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. A chemical analysis of either one length of flat-rolled stock or one tube shall be made for each heat.
Welded tubes shall be made using an automated welding process with no addition of filler metal during the welding process. Pharmaceutical aetm may be requested, as a supplementary requirement. No need extra polishing or smooth treatment. Optional supplementary requirements are provided, and when one or more of these are desired, each shall be so stated in the order.
In case specified in the order, intergranular corrosion tests shall be performed by manufacturer on specimens representative of the as-shipped condition.
Customers could specify the maximum roughness of internal surface, external surface and both surface. Sanitary stainless steel pipe and tube shall be capable of passing corrosion tests in the as-shipped condition. Each tube astmm be subjected to mechanical tests like reverse flattening test, hydrostatic test or nondestructive electric test.
Filler materials shall be noted added during welding process. Customers could specify the maximum roughness of internal surface, external surface and both surface. Mechanical tests includes negative flattening test, hydrostatic or nondestructive electric test. Filler materials shall be noted added during welding process.
