Pitting corrosion, or pitting, is a form of extremely localized corrosion that leads to the creation of small holes in the metal. The driving power for pitting corrosion is the depassivation of a small area, which becomes anodic while an unknown but potentially vast area becomes cathodic, leading to very localized galvanic corrosion.
A mill test is a procedure used to evaluate the quality and traceability of steel products from the manufacturing process to the final end user. It is reported in the form of a certificate that summarizes a variety of data including steel concentrations, processing activities and chemical and physical examination results, thus allowing one to ...
Dec 26, 2008· It can be from the mill itself if they have the equipment or by an outside company who tests for the mill. 3. I can see where they might want a certificate showing what was used to make the PU coating or even a MSDS sheet from you the supplier but a MTR is just that, a MILL test report so sounds to me like they want it for the pipe. 4.
Recommended Practice and Procedure for the Use of Corrosion Coupons In practice, the corrosion coupon is one of the most useful tools for monitoring corrosion. Coupons provide accurate results at a reasonable cost, are easy to use and can provide general information that is both quantitative and visual on many types of corrosion.
