May I ask where the boundary between the instrumentation specialty and the piping specialty lies? ? Do the connectors or valves connected to the instruments belong to the piping or to the instruments themselves? ? How is it considered reasonable?
Based on the valve division, refer to HG/T 21581-2012 Automation Installation Manual
The primary valves and connectors connected to the instruments are all part of the instrumentation field; for example, the pipes and valves from the pressure sampling point’s primary valve to the instrument also belong to the instrumentation category
The specification \"Design Division of Automation and Piping Specialties\" HG/T 20636.2-1998 provides detailed provisions. Appendix A of the \"Technical Specifications for the Construction of Petrochemical Instrumentation Projects\" SH/T3521-2007 also contains it.
Does the question refer to design or construction? In practice, there is some overlap.
Follow the regulations of your own organization; in our facility, it depends on what type of interface the instruments have, and the pipes are fitted with materials corresponding to that. The instrumentation team will provide the installation condition diagrams for the piping team.
