The main types of tests and services
We carry out the full scope of standard mechanical tests, as well as corrosion tests and the strength calculations.
Static tests
- Static tensile test, compression test, bending test, flattening and torsion tests
- Shear strength test and cut test method
- Determining of the crack resistance characteristics such as K1C / CTOD / J1C, Young’s modulus, shear modulus, Poisson’s ratio
- Measurement of hardness and microhardness
Cyclic testing
- Multi-cycle fatigue test
- Low-cycle fatigue test with the stress control (the soft and hard loading)
- Determining of the cyclic crack resistance characteristics
Dynamic tests
- Determining of the impact strength characteristics
- Impact fracture of the corner welded joints
Welded joints macro section
- Hardness determination in the different weld zones
- Macroscopic analysis
Metallographic studies of the materials structure
- Macrostructure research
- Microstructure research
- Research of metal fractures
- Fractographic analysis of the damage surface
Corrosion Testing *
- Test for the sulphide and hydrogen cracking
- Determination of the corrosion and contact corrosion resistance (GOST 9.908)
- Test of the intercrystalline corrosion resistance (GOST 6032) and tests for the resistance to pitting corrosion (GOST 9.912-89)
- ASTM G39 Test
- Corrosion cracking test with the electrochemical method (OCT92-4395-86)
* – with the involvement of a third-party accredited structure
