Analysis of Revision and Implementation of Standard GB/T 23802 for Corrosion-resistant Alloy Seamless Tube

Elaborated here in the paper are the changes of the structure and technical contents of Standard GB/T 23802 for corrosion-resistant alloy seamless tube as made via the first revision thereof. Under the revised standard there are two product specification levels,and for PSL-2 products some additional requirements are specified. And supplement and completion are made for the technical requirements concerning such aspects as NDT,impact toughness,defect,purity,flattening test,documentation and marking,etc. Furthermore according to the country's oil and gas field characteristics and present situation of production and R & D of the corrosion-resistant alloy seamless tube,suggestions associated with revision and implementation of the said standard are put forward.
