6、ity (3.5, 3.5.2) and Acceptance Tests (4.2.1.1) to add nondestructive testing requirements to all tubing. 1. SCOPE 1.1 Form This specification covers a corrosion-resistant steel in the form of seamless or welded tubing. 1.2 Application This tubing has been used typically for parts, such as fluid lin
7、es, subject to medium high pressures and requiring corrosion resistance, but usage is not limited to such applications. Welding, brazing, or other exposure to temperatures over 800 F (427 C) during fabrication may impair corrosion resistance. 1.3 Classification The tubing covered by this specificati
8、on is classified as follows: Type 1 - Seamless Type 2 - Welded and drawn 1.3.1 Unless a specific type is specified, either Type 1 or Type 2 may be supplied. 2. APPLICABLE DOCUMENTS The issue of the following documents in effect on the date of the purchase order forms a part of this specification to
9、the extent specified herein. The supplier may work to a subsequent revision of a document unless a specific document issue is specified. When the referenced document has been cancelled and no superseding document has been specified, the last published issue of that document shall apply. SAE INTERNAT
