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
- Check the surface. Such as visual and touch to avoid dents, die
marks, porosity, undercuts.
- Ensure the marking is clear. The marking includes name size,
material grade, pressure, heat No.
- Confirm that the size is within tolerance according to the standard
chart
- 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.
