Dimensional check and visual inspection
- Dimensional and visual inspection of the expansion joints and welding seams in accordance with DIN EN ISO 17637
Non-destructive test (NDT)
- Dye penetration test (DP) in accordance with DIN EN ISO 3452-1
- X-ray in accordance with DIN EN 1435
Leak test according to DIN EN 1593
- Leakage test of the expansion joints
vacuum test according DIN EN 13185
- Leakage test of expansion joints and hoses with helium at vacuum down to < 1x10E-8 mbar*l/s
Pressure test according DIN EN 13184
