Talk about unjustified fails. (Though he probably could have been more selective with his words)
I've worked for various companies that import billions and billions of dollars in materials for pipeline and petrochemical plants. My position requires me to be very familiar with documents common in many industries known as "AML" or "Approved MFG List". This document contains all the manufacturers, their specific plant locations, and what products they are approved to supply. It's extremely specific, for pipe it would list approved type/grade/diameter/wall thickness etc.
Now what's interesting is this, all the major pipeline companies have banned Chinese pipe. Too many instances of failures on hydrotest, too many material test reports with missing information, incorrect information, or that can clearly be traced back to measurements taken years before that batch was made etc.
We've had third party labs test materials sourced from China on various occasions and virtually every single time we have observed material properties that do not meet the applicable material standard, and also do not reflect the results obtained in China when they "did their testing...".
That's not to say all of China's MFG sector is crooked and will do anything to make an extra buck, but it's IMO very common to take shortcuts.
We simply issue a memo now which basically states if you see any material test reports that have a Chinese address, quarantine the materials and return them.
I have personally seen Chinese material fail under hydrotest, and on that occasion, we were only about 60% of the SMYS. (Explained in simple terms: we tested to 6000Kpa of pressure and the pipe failed, pipe that "should" be good for 10000Kpa based on the material type/grade specified.)
So why do people buy Chinese pipe? Because it's cheaper, and the distributors here also want to make some extra money :s
