What is a Steel Pipe MTC?

 

Quick Answer: A steel pipe MTC is a document that records material identification, chemical composition, mechanical properties, and applicable test results to demonstrate compliance with specified requirements.

 

MTC is used interchangeably with steel pipe mill test certificate, steel pipe material test certificate, and steel pipe material certificate in most B2B transactions — they refer to the same type of document, typically issued by the manufacturer or mill that produced the pipe.  

 

What a specific MTC must contain depends on the standard called out in the purchase order (such as an ASTM, API, or EN specification), the product type, and any additional requirements agreed between buyer and supplier. Not every steel pipe MTC will contain identical fields, and buyers shouldn't assume one standard's requirements apply to a pipe ordered under a different standard.
