Which specialty is responsible for the pressure tapping pipe of the nitrogen seal valve in storage tanks?
Thread Content
I would like to state upfront that I am not a specialist in storage and transportation; my field is process piping； I recently encountered a storage and transportation project that involved an issue related to the pressure tapping tube for a nitrogen seal valve. I believe that the pressure tapping tubes for instruments and valves fall under the scope of the automation engineering field, but some colleagues say they belong to the pipeline engineering field. Therefore, I would appreciate it if someone from the relevant field could provide an authoritative explanation. I will reward the person who does so with a reply. Thank you.
On the drawing, just divide it into interfaces, right? Generally, provide a branch pipe to divide at the flange, or use a pipe socket with threaded connections for division.
According to the regulations of the design institute, some are classified under the piping specialty; after all, the definition of equipment refers to the first flange on the external connection pipe of the equipment
