LT Integrity: Certificates That Refuse to Be Spreadsheets

ltintegrity.com Observed source
Editorial interest 79/100 Selection signal · not a rating of the site

A Spanish-language platform that records and certifies industrial valve tests and fire-pump acceptance tests with QR/NFC traceability and web validation.

Landing page captured for the 2026-09-16 issue.

Field notes

LT Integrity separates two testing workflows: API 6D/API 598 valve certification and NFPA 20/NFPA 291 fire-pump acceptance. Its described controls include a required Backseat → Cuerpo → Sello sequence, pressure-by-class tables, weekly probe calibration for test-water chlorides, and real-time pressure graphs. Certificates receive QR/NFC-linked equipment identities, while corrected records create a new traceable entry rather than silently changing the original.
