Ordered pipes not in compliance with technical specification
Ordered pipes not in compliance with technical specification
(OP)
Hi!
We have a situation of a dispute with a delivery company about pipes we ordered from them.
In the project technical specification, it was clearly specified and underlined that only longitudinally welded pipes are acceptable for use in this project.
After we received their offer, we checked it for mistakes/issues but not thoroughly enough only to find out later that spirally welded pipes were delivered to the construction site.
Of course, at this point they are blaming us as the ones who are responsible for this situation!!?
Any advice for this situation, any experience with this kind of issues.

Doesn't really matter what you asked for. If they gave you an offer based on a different type of pipe and you accepted their offer then that often takes precedent.
You need to dig out the PO and see if it still referenced your spec and data sheet or just their offer.
In any event spiral weld is the same in terms of design as straight welded so you can use it just the same so long as the thickness and material grade are correct.
Did you have no inspectors at the mill??? Or a KOM??

RE: Ordered pipes not in compliance with technical specification
To reject this pipe and then be able to justify it you really need to find a design reason apart from what it says on the spec.
Hint: There isn't one.

Your spec doesn't matter if you give them a way around it.
Make procurement and legal do their jobs.
Tell then that you are rejecting it for technical reasons, then let them decide if you have a leg to stand on.

Q2: why was linear weld specified in your requirements?

Between a straight weld seam pipe and a spiral welded one?
Seamless and welded I fully accept there is a difference, but welded is welded surely? Length of the weld is surely irrelevant?
3D - I get that spirally welded pipe just looks a bit odd, so I guess they thought there was a chance someone could offer spirally welded, which is often a bit cheaper, so wanted to be clear that it wasn't what they wanted. But now they've royally screwed up by not reading the quotation properly. IMHO.

Not as far as I'm aware. I think a lot is just prejudice from some dodgy pipe 50 years ago. Because you're moving the pipe axially as well as rotating it you can get the arc weld seam a bit off centre. Plus there is more weld.

It’s all in the expansion. UOE/JCO SAWL is expanded, generally altering the stress state of the weld in a positive manner with respect to sour service. It is also has more controlled dimensions that render it more attractive for high productivity offshore welding.

Sorry, but what is in your project specifications means absolutely nothing if your procurement department has not communicated requirements properly.
If they have and the offer was something else entirely then it falls on you - the QC department.

I suspect though it's for none of those things....

As far as I remember Kletz's What Went Wrong 5th ed. - an industry survey showed that 5% of all piping components do not comply with design specs.

Dik,
"There was an incident of piping supplied for an airport in Winnipeg a few years ago was substandard. It was failing at 1/10 of the design pressure. It was supplied from China and the test data was exact for all piping, only the test report number varied..."
Received 2 x plates from a mill in China - totally different heat numbers, totally different Lot numbers, totally different thicknesses.
MTC's reviewed on their own showed compliance with the required standard (that is what the contractor did).
Me, being an old fart who has been around the block a few times reviewed them side by side.
Every single mechanical result exactly the same, every single element of chemical composition exactly the same down to 0.001,
I hate to "tar all Chinese mills with the same brush" as there are some very good mills in China - unfortunately my contractors never pick them. $$$

We received valves with pressure test certs for the seats but the valves did not have the seat rings installed.
For best results we send an inspector from our country to the factory to witness the process and testing
RE: Ordered pipes not in compliance with technical specification
My only incident with Chinese manufacturing... I don't have a problem with China; generally their stuff is good. It was just funny that the data was all the same. The same material had passed through maybe a dozen other engineers, and not notice.

Thank you for the assistance - will give it a try.

Yes it took me about ten years as well to figure it out....
The OP meanwhile hasn't been seen since Friday... maybe he got fired for buying the wrong pipe?

Thank you Steve and Li

We still visited to witness regularly.
But then we had a rule that if we bought from someone twice we had to witness at least once.
It didn't where they were located.
One reason that many of the Chinese mills had/have issues with test reports is that there is no internal communications.
The chem lab and mech test labs had might as well be outside companies, and no one has any stake in the outcome.
