Package of Stainless Steel Threaded Fittings
We marked all Stainless Steel Threaded Fittings with Grade, Lot No, Size, Standard and Pressure. The workers sleeved 3 inch NPT Threaded Cap SS 316 into plastic bag individually, put all of them into cartons and wooden cases, then bundled package with nylon rope.
Clear labels are tagged on the outside of the package for easy identification of the quantity and product. Great care is taken during operation and transportation.
Inspection of Threaded Cap
Visual the surface of threaded cap body. Such as dents, die marks, porosity, undercuts.
Check the marking. Such as size, material code, grade, thickness, heat no.
Measure dimensions. Such as outside diameter, wall thickness, height from end to end.
Test the chemical composition of stainless steel threaded caps.
Test the thread by go/no gauge
