Production control
Before production, material grade, standard, pressure rating, dimensions, drawing requirements and certificate needs are reviewed. During production, dimensions, facing, drilling, marking and surface condition are checked.
This page explains the practical manufacturing and order control points that matter to European importers: standard confirmation, material traceability, inspection, marking, packing and shipping documents.
