It depends on what your company or customer requires, as sated in specs or on the purchase order. I require an MTR for everything that will be used on a pressure vessel, although the code, my QC manual, or the AI do not require it. MTR's on only REQUIRED by code for certain product forms.
However, the reason I require them is to simply assure myself, and to verify that the material is traceable and does meet the applicable spec of the product ordered. If allowed, it is acceptable to take the suppliers word for the material supplied, but why risk it.
As for forged products that require certain stamping and marking requirements, in some cases that is good enough and no MTR's or C of C's are required. Again, it all depends on specs and code requirements.
I do usualy get MTRs, for the ongoing projects, but we have many business units so sometimes i do not get them.
I dont want to chase my tail for somthing that is not Required or asked for on the PO.
in this case i did recieve a C of C but like you i usualy get everything.
Just wanted another opinion on this.
Thx

Just a question - I work for a water district and do receiving inspection on a whole bunch of flanges
We inspect per the spec but the biggest problem I have is getting the TWO hardness tests that are specified -
companies that give an AVREAGE reading. When I get that B.S. I tell them that I"d llike to see their original
data and then they move their big toe around in a square pattern on the floor -
WHATS THE CODE REQUIRE FOR REPORTING?
if its required that the values be reported reject the lot.
if its not speak with the purchasing dept ask them to require actual values on the PO and state po will not be paid untill all documentaion is recieved, then if they are not provided reject them or accept them pending documentaion but dont pay untill its recieved.
But if its not required by code and not on the po i dont see how you can do anything besides call and ask every time.
Thats what id do, but im a pain in the arse to my purchaser (but my concerns are warented).

The question is; "Do you trust your supplier or the manufacturer?"
Have you ever heard of "China Flanges"?
Even if you have the CMTRs, there is no guarentee they are not "pencil whipped".

Let's not give pencil whippers a bad name. I think the word you are searching for is "counterfeit".
counterfeit [koun-ter-fit]
-adjective
1. made in imitation so as to be passed off fraudulently or deceptively as genuine; not genuine; forged: counterfeit dollar bills.
2. pretended; unreal: counterfeit grief.
-noun
3. an imitation intended to be passed off fraudulently or deceptively as genuine; forgery.
4. Archaic. a copy.
5. Archaic. a close likeness; portrait.
6. Obsolete. impostor; pretender.
I know about China steel and flanges, Dont wanna think about it though, we rarley get China anything. We do get a lot of tiwan , and india though....any better who knows.
Thats one good rason to get a hand held PMI.

"pencil whipped".
WHATS THAT?
Tito,
Is is true that all plate MTRs must reviewed.
So there is no case where a shop QC dept would not recieve a MTR for say SA 516 GR70. purchased by them.
I'm not quite sure if you asking a question or pointing out that plate needs to be inspected.
Either way, yes plate for for pressure boundaries do need MTR's. In my post above, I was simply stating that MTR's are not required for everything according to ASME sec VIII, just certain product forms, such as plate.
