The catalog of special equipment has been updated, and it differs from the pipe grade classification specified in GB20801. Has the GC3 grade been classified as GC2 according to the new catalog of special equipment?

It’s clear that the original GC3 has been merged into GC2.

I’m a bit confused now; there are no clear guidelines defining it.

Yes, the new licensing rules – there’s no Gc3 anymore.

Both are right, whose fault is it? Messy

Originally GC3 grade; only the liquid pipelines remain in GC3. The latest electronic version of the regulations is now available
