The National Petroleum Pipe Quality Inspection and Testing Center was established in 2006 with the approval of the State Administration for Market Regulation (formerly the General Administration of Quality Supervision, Inspection and Quarantine) and the National Certification and Accreditation Administration. It has also obtained CMA qualification certification and can provide data and results with certification to the society. The Quality Inspection Center is also the operating entity of institutions such as the Petroleum Pipe Testing Laboratory, the Pressure Pipeline Component Manufacturing License Appraisal and Review Institution, the Type Testing Institution, the Petroleum Industry Thread Gauge Measurement Station, and the Key Laboratory of the State Administration for Market Regulation (Petroleum Pipe and Equipment Quality and Safety). In 2024, the center obtained laboratory accreditation from Saudi Aramco, becoming the first third-party laboratory in China to receive its accreditation for acid resistant plates/tubes and failure analysis.
The quality inspection center has 95 professional and technical personnel, with over 70% holding a master's degree or above and a deputy senior professional title. It has built a high-level technical team with complete specialties and a reasonable structure; The laboratory covers an area of over 20000 square meters and has 580 testing instruments and equipment per set, which can achieve full coverage from microstructure analysis to full-scale physical simulation experiments; CMA and CNAS have authorized inspection and testing capabilities covering 69 major categories of industrial general products in the petroleum pipeline and petroleum industry, with more than 760 testing standards and over 400 testing projects. They can provide technical services for product and material inspection, testing, and quality evaluation for the petroleum pipeline and equipment industry.
