FAQ

Q: How does re-testing improve safety?
A: By verifying stress relaxation, it ensures that residual stresses remain within safe limits.

Q: Can it be used on live pipelines?
A: Yes, it is designed for in-service testing without disrupting operations.

Q: What is the minimal distance between test points?
A: The indenter spacing depends on material; typically about 1 mm to avoid interference.

Q: How long does a single test take?
A: Due to high loading speed up to 30 mm/min, each test can be completed in seconds.

Q: Is data analysis software included?
A: Yes, the system includes data processing and analysis software.
