Marking and Packing

• Marked with Grade, Lot No, Size, Standard and Pressure.
• Packed socket weld fittings into cartons and wooden cases.
• Tagged labers on the outside of the package for easy indentification.

Inspection   

1. Check the surface. Such as visual and touch to avoid dents, die marks, porosity, undercuts.
2. Ensure the marking is clear. The marking includes name size, material grade, pressure, heat No.
3. Confirm that the size is within tolerance according to the standard chart
4. Test the chemical composition of material stainless steel 304 

Features of Socket Weld Coupling

● 6000# Socket weld coupling is applied for 4” under pipe system

● High leakage integrity

● Great structural strength

● Lower fatigue resistance than butt weld fittings

● Can be used to flammable, toxic, high pressure and high temperature pipeline.

● Designed to provide good flow characteristics

● No need for alignment.
