Original situation
RE: CHINESE STUDBOLTS
roca's photos are for a supposedly recent case of failed bolting on a valve. The report I was forwarded says the following in regards to his photos,
"One of my associates in Texas was inspecting a new 16" 600# valve when he found this. I guess they ran out of 12" studs?"
Hence, there is not enough information to know where the source comes from and when it happended. To state "Chinese Bolts" as a title is erroneous unless proof is provided to support the claim.
Be wary of those failure e-mails that circulates around. I take them with a grain of salt unless I know exactly where the source comes from before I trust the information. Treat it like chain mails and gossip.

RE: CHINESE STUDBOLTS
Agree with you. These pictures were circulating around a few weeks ago BUT without the full story of where they were from. You cannot "slate" anyone without the full accurate story behind the photos.
RE: CHINESE STUDBOLTS
My reply to roca's first post crossed a few seconds late the second roca post with attachment...Only hours earlier I received a formal alert about another failed batch of Chinese studbolts, breaking during the bolts tensioning. The sad part was the date of original post/alert, some close to fall 2006. Took almost 15 months to reach me. I thought the first post from roca referred to it...However, I cannot find any justification for the act shown on the photos, not even your "politically correct" attempt to divert the attention from the fraud described in the picture. Even if roca did not present hard evidence of the fraud originated from China, it is usefull to have a reminder that this fraud could be just another chinese act on the long list of similar acts.

RE: CHINESE STUDBOLTS
I agree more evidence is required and I just passed the info on as it was sent to me.
In the end it doesn't matter where it was manufactured, its the fact that it was allowed to happen. I've never seen anything like it.
Inventive yes - but what ever happened to QA and inspection.....??
RE: CHINESE STUDBOLTS
I do not know the full story behind this - but would like to. The only thing that one should bear in mind is the poor unknowing sod who could be stood near the equipment when it starts up and get to hydrotest pressure or operating pressure. Manufacturers doing these sorts of acts should be "named and shamed" as it's peoples lives they are messing with.
RE: CHINESE STUDBOLTS
If you always insist on the low bid, don't be surprised when this happens.
RE: CHINESE STUDBOLTS
I know exactly what you mean. The PM's tend to go for the low bid all the time , without having the technical knowledge to make the decision, apart from cost, as it always makes them look good to the upper management. When thing's go wrong though they put on their Teflon shoulder pads.
