Raw Materials Receiving Inspection

Kepl butt-welding fittings/socket weld fittings are made of materials which meet ASME/ASTM/IS/BS/DIN specifications. Raw materials inspection are carried out as follows:

1. Dimensional Inspection 2. Visual Inspection 3. Review of test reports as PO/Specn. 4. Specific requirements if any (NDT/IGCT etc.,)

In-Process Inspection

Kepl butt-welding fittings are manufactured with carefully selected materials of the finest metallurgical quality on well controlled jigs, tools or dies based on Kepl's various working standards.

The following are the major in-process inspection items.

Dimensional Inspection Shape Inspection Hardness Test Temperature Check(fittings only) Processing Conditions Check Raw Materials Identification (by marking) Heat treatment

o ASTM A234 WPB, WPL6: Stress relieved and/or normalized o ASTM A234 WP11, WP22, WP5, WP9, WP91: Normalized and tempered o High Yield up to WPHY80: Quenched and tempered o ASTM A403 WP304, 316, 321: Solution Annealed

Final Inspection

The final inspection of Kepl butt-welding fittings is performed as follows:

o Visual Inspection o Dimensional Inspection o Final Positive Material Identification (PMI) o NDT tests o Preparation of Inspection Certificates o After final inspection, each fitting is marked, by hard punching/electro etching (for SS ) with Kepl's trademark(KE),

nominal diameter (or outside diameter), wall thickness, Sepcn/grade and Batch no.
