API 5L Specification is standard for line pipes, but there are many requirements for different aspect, such as steel composition, test methods, carry methods, coating methods etc. So, in API 5L specification, many requirements are from other relevant standards in steel field. HYSP is like to share with your the reference norms in API 5L Specification.

The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
