China oil pipelines explode

China oil pipelines explode

RE: China oil pipelines explode

Would it be too early to blame Chinese Flanges for this incident?

RE: China oil pipelines explode

Could be the flanges or the pipe. Every chance the material is plastic but could be stamped up as being carbon steel!!!

RE: China oil pipelines explode

I'm siding with the UFOs for now.

RE: China oil pipelines explode

Could be lead pipe marked as carbon!!! Don't beleive anything marked on chinese material or the chemical compositions.

RE: China oil pipelines explode

Even at current lead prices, lead pipe would be a poor substitute for carbon if your intent was to save money!

Furnace welded pipe instead of ERW?  That I could see...

RE: China oil pipelines explode

The funny thing is that US companies are buying pipe from India and China, while China is buying pipe from the US!

RE: China oil pipelines explode

Strange that the Chinese are buying US steel instead of their own!! Doesn't that tell you something??

RE: China oil pipelines explode

Chinese buy special alloy steels abroad like we do with standard steels - and buy it in China.

RE: China oil pipelines explode

They likely bought it offshore <G>.

East wants to emulate the West in many ways and as usual with catastrophic results.  Yet, I don't uderstand why we still buy Chinese when we have so much superior stuff in the West.

RE: China oil pipelines explode

(OP)
Maybe the preceived value is higher for Chinese products, noting that precived value is often greatly exaggurated when low prices are evaluated in place of quality, rather than against quality.

Clearly, not enough duct tape.

Thanks for posting this BigInch, I've been putting together a presentation on pressure boundary (piping etc.) failures and have been collecting as many examples as possible.

RE: China oil pipelines explode

chicopee,
         Reason why materials are purchased from China is that they are cheap and the "bean-counters",MBA's in charge of engineering make the decisions. It's all about cost nowadays not whether the item is "fit for purpose" and has quality written all over it. "Cheap and nasty" is the way most Project Managers want to play it. In many Companies if they save costs it means more "bonus" at the end of the Project for them. They strive for savings everywhere so more cash goes in their pockets (not the hard working engineer helping along the way). So long as these "bean counters" accept responsibility when things go wrong but they always point the finger at "engineering".

RE: China oil pipelines explode

Kudos and AMEN..!!! DSB...You nailed it...

Greed will always trump all common sense and MBAs will always shift the blame to underlings..!!!

 

   

RE: China oil pipelines explode

Regarding the posted thread... Dig1:

Based on this and another project I am aware of in China, the material cetificates must be looked at very critically. I know of some end-users that are no requiring 3rd party testing witnessed by an end-user rep of material.

You have to be really certain about the material certs... on one project, that is an ongoing problem, we have the same material certs for different test heats... only change is the location of the test and the heat... so you have to be careful about that, too.

Might be better to insist on independent testing by a 'reputable' lab... testing of all components... this may have an impact on the 'savings'.
