Destructive Tests
| Test | Explanation |
|---|---|
| Impact Testing | Measures energy absorption at low temperatures. |
| Tensile Testing (Proof Load, UTS & % Elongation) | Assesses strength and elongation under tension. |
| Flattening/Reverse Flattening Test | Tests resistance to compression deformation. |
| Guided Bend/Reverse Bend Test | Checks weld ductility by bending pipes. |
| Flaring/Flange Test | Assesses pipe expansion and flange forming ability. |
Non-Destructive
| Test | Explanation |
|---|---|
| Chemical Testing | Analyzes chemical composition for material conformity. |
| Hardness Testing (Rockwell & Superficial Scale) | Measures hardness and resistance to wear. |
| Eddy Current Test | Detects surface and subsurface flaws using electromagnetic fields. |
| Liquid Penetration Test | Reveals surface defects using penetrant and UV light. |
| Visual & Dimensional Inspection | Inspects surface and dimensions for imperfections. |
| Pneumatic Test | Checks leak-tightness by applying air pressure. |
| Real-Time Radiography | Uses X-rays to detect internal defects, especially in welds. |
| Automatic Visual Inspection | Conducts automated surface inspections for defects. |
| Remote Visual Inspection | Uses cameras to inspect pipes in hard-to-reach areas. |
| Ferrite Test | Measures ferrite content in welded areas for quality. |
| Positive Material Identification (PMI) | Verifies material composition using XRF. |
| Hydro Testing | Applies water pressure to check for leaks and deformations. |
