Classification of pressure pipelines
Thread Content
I would like to ask everyone: which standard is currently used as a reference for classifying pressure pipelines? 1. Announcement by the State Administration for Market Regulation in 2019 regarding matters related to administrative licensing for special equipment, effective as of June 2019. Among them, the pressure pipelines of GC3 grade 2 and GB/T20801-2020, \"Code for Pressure Piping – Industrial Piping\" Part 1: General Provisions, which was issued in October 2020, have been removed; meanwhile, pressure pipelines of GC3 grade are still retained. May I ask which code should be followed for classifying pressure pipelines at present?

1. Announcement by the State Administration for Market Regulation in 2019 regarding matters related to administrative licensing for special equipment, effective as of June 2019. Among them, the GC3 category of pressure pipelines has been removed. Currently, GC-category pressure pipelines are divided into GC1, GC2, and GCD categories
Following this, GB/T20801-2020, \"Code for Pressure Piping – Industrial Piping\": as long as it can be explained clearly and there is a basis for it, the latest version should be used
In accordance with GB/T20801-2020, but according to this standard, GC3 is hardly used
