Heat number. An example of a heat number on a plate. A heat number is an identification coupon number that is stamped on a material plate after it is removed from the ladle and rolled at a steel mill. Industry quality standards require materials to be tested at the manufacturer and the results of these tests be submitted through a report, also called a Mill Sheet, Mill Certificate or Mill Test Certificate (MTC).
Welding effect on internal pipe cement lining. I have a question on the effect of welding heat on the internal cement lining of mild steel water pipes. Is it possible for the heat during welding of collars, flanges etc. to damage these cement linings? Currently involved in a project where we have a 15 inch ND MSCL pipe for a curved bridge crossing.
