FAQs
1What is the difference between PT1-P41 and PT1-P41-1 / PT1-P41-2?
PT1-P41 is double-sided printed with torque and retorque log table on the back. Every tag set has laser engraved unique sequential TAG NO. for full traceability, specifically built for high-risk flange projects and strict regulatory audits. PT1-P41-1 and PT1-P41-2 are single-sided versions without serial numbering.
2How does the sequential numbering system work?
Each segment of the whole tag set shares the same unique TAG NO. When technicians tear off coloured slips for archiving, the main tag and filed slips can be matched easily for audit, so every flange joint can be tracked individually.
3What data can be logged on the back side of PT1-P41 flange tag?
The reverse side has dedicated fields for torque, tension value, System No., Line No., PMD No., tightened / tested by and date, plus a torque interval table for future re-torque maintenance management.
4Can this tag withstand harsh offshore environments?
Yes. The PVC material is tear-proof, weather resistant, waterproof, oil and chemical resistant, suitable for offshore platforms, refineries and other demanding industrial sites.
5What projects are PT1-P41 sequential numbered flange tags best suited for?
It is recommended for large-scale shutdown, turnaround and commissioning projects with high-risk flanges, where full traceability and regulatory audit compliance are mandatory.
