- Critical joint consultation, Inspection & Monitoring – Supply of competence personnel, Technical support, and advice
- Controlled bolting works (MTW, HTW, HBT) – Hot bolting/Odd Bolting
- On-Site Machining – Cold cutting and bevel
- Flange resurface, repair – weld build up & replace
- Thorough inspection and supervision by competent personnel at 3 major stages (recommended for best result)
Stage 1: Preparation-material selection & purchasing, joint identification (line walk-visual inspection)
Stage 2: Installation – witness and inspection on site during job execution (Procedure & method of tightening-provide optimum torque & tensioning value)
Stage 3: Handover – final report and database record-traceability ensured & easily accessible
- Flange Management software (ATW – INTEGRITY PRO)-comprehensive database system
- Leak Testing (Hydrostatic, N2, Helium)
- Leak sealing (On-line using clamp / Pipe Freezing-temporary pipe isolation by creating freeze plug)
- Real-time condition-based monitoring (Live monitoring on critical joint)
- Bolt Load verification (UT Tools)
Typical elements (as per EI Guidelines) for Joint Integrity assurance are as follows:
- understanding of the operating environment
- continues with design
- selection of the flange components
- setting of assembly specifications
- establishment of best procedures
- appointment of competent personnel
- quality assurance traceability through complete documentation (using sophisticated and systematic software for database)
- finishes with meeting the goal of leak prevention
