How to fill in the equipment type column in the pressure vessel product data sheet in a standardized manner
Thread Content
In pressure vessel manufacturing design drawings, the design generally does not provide the usage of the equipment, so how can it be characterized? Some of the types of equipment in the pressure vessel product data sheet are filled in according to their uses (the four categories of reaction, heat exchange, separation, and storage in the solid capacity regulation). For a product that cannot be clearly characterized, you can only rely on your own understanding to choose and fill in the uses. Is it appropriate? Can there be a standardized explanation?
When writing the product drawing number, the type of equipment must be reflected. For example, for a storage vessel, the first two letters of the drawing number are "RC", the reaction vessel is "RR", the separation vessel is "RS", and the heat exchange vessel is "RE". You can know the function of the container at a glance.
Is it an internal company norm? still * * Or industry regulations? Many of the equipment I come into contact with cannot be seen from the design drawings based on the drawing number compilation requirements you mentioned.
Drawing numbers are all set internally by the company for management purposes.
You can ask customers to provide it! Sometimes customers don’t know exactly what equipment they need. You can communicate with the customer or specify it on the design drawing, so that you can avoid your legal responsibilities.
There have always been the same doubts. At present, we classify based on the rules and our own understanding.
Ask the equipment design unit or design institute
The purpose depends on the design unit and the user unit.
This is the written text I saw involving the word "variety" of equipment. It comes from the "Special Equipment Catalog" of the General Administration of Quality Supervision, Inspection and Quarantine.
It seems that the owner is not proficient in the technical specifications. Please ask the technical person in charge for advice. TSG 21-2016 3.1.3 Design condition A4 use division
