On-Site Assessment
Our team is deployed to your facility to conduct an in-depth inspection and use advanced diagnostics to pinpoint the root cause of failure.
Flexible Execution
We offer flexible solutions, including **In-Situ (On-Site)** repair to reduce costs, or **Ex-Situ (Workshop)** repair for complex fabrication work.
Precision Replacement
We procure or manufacture all replacement parts (tubes, baffles) to meet API/ASME standards, using state-of-the-art expansion tools.
QC & Guarantee
No unit is returned without passing rigorous QC checks, including hydrotesting and leak detection, ensuring it performs like new.
Final Quality Control (QC) & Performance Guarantee
| QC Inspection Aspect | Test Method | Purpose |
|---|---|---|
| Pressure Integrity | Hydrotesting (Tube & Shell) | Verifies structural integrity and confirms zero leakage under maximum design pressure. |
| Micro-Leak Detection | Helium Leak Test | Detects minute leaks often missed by standard pressure tests, critical for vacuum applications. |
| System Sealing | Pneumatic Test | Confirms the integrity of flange joints and final assembly seals before fluid introduction. |
