What are most frequent destructive tests for fittings

What are most frequent destructive tests for fittings

1.Bending: fittings are bent until deformation appears on their side, face or root.

2.Charpy impact: named after Georges Charpy who developed it, this test measures toughness of a fitting by determining the amount of energy absorbed during its fracture from impacts.

3.Corrosion: fittings are exposed to corrosive fluids or materials until corrosion appears.

4.Metallographic: this test studies physical structure and components of metal samples, typically by microscopy. Samples are taken from actual fittings.

5.Tension: fittings are stretched until deformation appears; measures are taken for strength, yield, elongation.
