FAQs
1What is the difference between PT1-P51 and PT1-P51-1?
PT1-P51 comes with laser engraved sequential TAG NO. on every tag segment for full traceability, ready for strict regulatory audits. PT1-P51-1 is the standard 5-stage version without pre-printed sequential numbering.
2What is the function of the blue "FLANGE BROKEN" slip?
The blue segment lets technicians mark defective or damaged flanges during inspection. It can be torn off and submitted to supervisors, adding fault tracking capability to your flange workflow records.
3How does the sequential numbering system work?
Every segment of one tag set shares the same unique TAG NO. When coloured slips are torn off for archiving, the main tag and filed slips can be matched easily for audit, so every flange joint can be tracked individually.
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-P51 sequential numbered flange tags best suited for?
It is recommended for large-scale shutdown, turnaround and commissioning projects with high-risk flanges, where full end-to-end traceability and regulatory audit compliance are mandatory.
