Non destructive testing
Control of superficial defects of the fixing elements once manufactured or in the state of supply. The controls are carried out according to the standard or specification established in each case, in order to reveal defects that may cause catastrophic failures in service.
The tests carried out by certified personnel (AEND).
- Visual inspection
- Ultrasounds
- Magnetic particles
- Penetrating Liquids
- Axial computed tomography
Destructive testing
These tests are carried out in accordance with international ISO and ASTM standards and on geometries and metrics of all kinds.
- Tensile tests on fixing elements: finished screw, with wedge, on machined specimen
- Load tests (preload capacity up to 3000kN and a maximum torque of 30000 Nm)
- Shock bending tests (charpy)
- Hardness and surface hardness tests
- Decarburization and carburization tests
- Breaking torque tests
- Head strength tests
