Standard Specification for Seamless and Welded Austenitic Stainless Steel Sanitary Tubing
1.1 This specification covers grades of seamless, welded, and heavily cold worked welded austenitic and ferritic/austenitic stainless steel sanitary tubing intended for use in the dairy and food industry and having special surface finishes. Pharmaceutical quality may be requested, as a supplementary requirement.
1.2 This specification covers tubes in sizes up to and including 12 in. [300 mm] in outside diameter.
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.4 Optional supplementary requirements are provided, and when one or more of these are desired, each shall be so stated in the order.
