Pressure vessel inspection
Thread Content
The pressure vessels produced by our company are exported, and third-party inspection is required; production is carried out in accordance with GB150. Which testing institution in China is considered the most authoritative?
I recommend Harvard in the United States; the other options include ABS in the U.S., BV in France, SGS in Switzerland, and TUV in Germany.
It is manufactured in accordance with the GB series and has passed certification in China; so no third-party verification should be required, right?
It mainly depends on the requirements of the importer. .
For exports, CMA and CNAS are required
For exports, third-party inspection in the domestic market is required. Our products already come with reports from specialized inspection agencies, but these are not recognized abroad
What is needed are domestic third-party tests; foreign tests do not follow the national standard of 150 for evaluation
By the way: what standards are referenced for the hydrostatic test of gas-fired steam boilers?
Anyone qualified will do; as for authority, that’s hard to say.
What does this special type of equipment have to do with things like CMA, CML, and CNAS?
