A third-party report is only as credible as the metrology traceability behind it. We anchor our data to the national value-traceability chain.
Dongying Industrial Product Inspection & Metrology Verification Center
A comprehensive testing institution formed in 2021 by integrating the city's former quality-inspection, metrology, and fiber-inspection institutes. It hosts two national centers — the National Petroleum Equipment Product Quality Inspection Center and the National Petroleum Refining Product Quality Inspection Center — plus three provincial centers for petroleum equipment, petrochemicals, and non-ferrous metals.
It shares LEISA's home base — Dongying, China's largest oilfield-equipment manufacturing hub — and its specialty is exactly ours: testing oil tubing, casing, line pipe, drill pipe, and non-metallic composite flexible pipe and fiberglass pipe. Through its 124+ public metrology standards, every LEISA measurement traces back to national references.
