What are the special requirements for instruments and valves on GC1, GC2, and GC3 pipelines?
Thread Content
I would like to ask everyone: are there any special requirements for the local and remote control instruments and valves installed on GC1, GC2, and GC3 pipes? Is special certification or inspection required?
Are the special requirements you mentioned related to the material or to testing?
This is the classification of pressure pipelines, which relates to the inspection of such pipelines as well as special equipment. It’s sufficient that the material of the instruments installed on them, along with their pressure rating and temperature tolerance, meet the required standards; I haven’t heard of any need for special certifications or anything similar.
Pressure pipelines need to be inspected regularly; I haven’t heard of any requirements for valves.
Based solely on the pipeline category, it is difficult to determine the appropriate selection of pressure gauge valves. Be more specific about what kind of pipeline, medium, and other related details.
SH3005 instrument selection specifications: the instrument connections and materials must be at least as good as those of the pressure pipelines; special cases have additional requirements.
