Tips on buying pressure vessels from Asia
(OP)
Hello,
The company I'm working with is interested in buying pressure vessels from asian manufacturers. (their plan is to install them in Malaysia and also as a cost cutting measure) I've only purchased tanks from the USA and EU so i'm not too familiar with the quality of tanks in Asia.
We're not talking about high pressure (30psig) but the volume is 40000L and bigger. Is there any directory of tank vendors that have been verified to build to code? I'm trying to avoid flying around asia and visiting every vendor before selecting one. I would also appreciate any helpful tips on buying from asia. Thanks

We've been called on in the past to repair/ rebuild stamped pressure vessels that were brand new and had never seen service, but, that failed to meet Code. I'm talking recently. I'm talking about scrapping vessels and building new ones. Can you afford that?
As they say, 'Quality doesn't cost, it pays'.

I am currently working as the Australian contractors QC rep on fabricated structural modules in Thailand for shipping and installation to mines and O&G sites in Australia.
We are using one large fabrication company and have just been awarded two further structural steel projects.
As the size of these two projects warrants looking for other fabrication companies in Thailand I have audited 3 other companies.
One company I audited (Best Tech & Engineering) specialise in pressure vessel fabrication and they hold ASME certifications S, U, U2, PP - NBIC certifications NB & R and ISO certifications 9001 and 14001 from Bureau Veritas)
Very impressed with their set-up - not sure they are appropriate for our structural work but if I had pressure piping or vessels I would definitely be talking to them.
You should be able to get a world-wide register of ASME stamp holders from the ASME website - might be worth a look.
If I can be of any more assistance give me a call on +66 871 331 376,
Regards,
Shane

They were a reasonably small fabricator years ago, and one probably wouldn't of considered them, but now they are huge and have their fingers dipped in the pie globally. Aside from their huge expansion they maintain the same vessel shops (1 on the east, 1 on west cost of Malaysia), with their engineering house in KL. I have built many vessels here which went south to Oz. The local AI pulled up things that I, as a client rep let go, which is a good sign...
Are you thinking primarily SE Asia? The Koreans make fantastic vessels.
As far as tips... just simple old due diligence will do. Instead of flying here, you can request they put in a trip to your location in their quote for a clarification meeting.

If you feel intimidated about buying and using things made in China then don't go to Walmart or almost any other store nowadays. How could the early pioneers explore the land and found the ways to do things right?

For your initial order(s), as a minimum, perform a pre-award audit of the manufacturer's facility and QC organization and after award, conduct a preinspection meeting with representatives of your QC/Welding staff, Puruchasing and Engineering departments and your contracted international Inspection company's inspector (your primary inspection rep). Do make periodic visits to check on the effectiveness of your contracted inspector and the quality of the manufacturer's work.

This generated a lot of fear and discussion at the time, see thread330-172967: P91 failure in China - 3 fatalities. But I'm pretty sure that China buys Chinese products for their nuclear facilities.
Stress is a biological mechanism that improves strength at the expense of thought. It is counter-productive to solving technological problems.

Even further, for the even more critical items like pressure vessels for nuclear plants such as reactor and steam generators, China is planning to have them 100% domestically-supplied in the future. Plus, due to insufficient global nuclear manufacturing capacities/capabilities. Chinese manufacturers are mow gearing up to participate in the global supply of standard components of Westinghouse AP1000 and Areva EPR designs. See the news below:

I have no current reports since I have been out of the loop since that time
