Piping Material Matching What is Piping Material matching? A check to know if all materials required to fabricate a piping iso/spool are available at Site. In the positive the iso/spool is called a « Yes » iso/spool. It enables you to assess the workfront. To do the material matching you must allocate the BOM of the iso/spool to the materials in the Piping Material Management System. This is done by feeding the BOM with the iso/spool reference in the Piping Materials Management system.  © 2   0  1   6
