How can two storage tanks connected vertically and horizontally obtain inspection certificates?
Thread Content
The upper and lower storage tanks are connected together by pipelines; how should inspection be carried out – as if it were one piece of equipment, or as two separate pieces of equipment? Are there any regulations or standards in this regard that specify whether registration will be affected if supervision and inspection have been carried out?
Each storage tank has a separate “ID card”; how can you register them as “one”? The manufacturer might not be the same either, right? It’s better to keep them separate for easier management. Sometimes, going through the trouble is the way to save trouble.
If the two are connected together, the key is that the design drawings show them as two units combined
Are these two devices connected directly? Flange mouth to flange buckle? It wasn’t taken over. How many are there on the labels of the two tanks? How many pieces of information are there?
He hasn’t reached the stage where an ID card is required; this depends on how the design documents are formulated. If it is designed as a single pressure vessel, then it will be subject to inspection as one unit, while if there are two sets of design documents, it will be subject to inspection as two separate units. Anyway, the price is the same in any case.
The number on the nameplate – the “ID card”!
Both the storage tanks and the connected pipelines require inspection; check the documents issued by the General Administration of Quality Supervision, Inspection and Quarantine (website).
According to the equipment tag number, AB stations are counted as two
It depends on the construction drawings; when they are together, it’s just one drawing number, which is used as a reference
