GB/T 23802-2009
GB/T 23802-2009 Petroleum and natural gas industries—Corrosion-resistant alloy seamless tubes for use as casing,tubing and coupling stock—Technical delivery conditions
Abstract
This standard specifies the technical delivery requirements for seamless pipes made of corrosion-resistant alloys for casings, tubing, and rough-out fittings.
This standard applies to the following four groups of products:
—— Group 1: Including martensitic or martensitic/ferritic stainless steels;
—— Group 2: Including ferritic-austenitic stainless steels, such as duplex or super duplex stainless steels;
—— Group 3: Including iron-based corrosion-resistant alloys with austenitic microstructures;
—— Group 4: Including nickel-based corrosion-resistant alloys with austenitic microstructures.
This standard does not include provisions related to joint connections or other methods of connecting single pipes into pipe strings.
