Quality Assurance Capability
Inspection and Test Equipment
NPA adheres to the concept of lean management, with the goal of improving and ensuring product quality, bridging the gap between appearance and internal quality, and achieving full process quality control.From chemical composition, mechanical properties, metallographic structure to macroscopic dimensions and non-destructive testing, NPA ensures a dual inspection of online and laboratory testing, with a complete set of advanced testing equipment and an overall standard inspection process, making quality control more professional.
Testing and Research Institute
The company has established a testing laboratory in accordance with ASTM A608 standard, HG/T2601 standard, HG/T3673 standard, and Sinopec Corporation (2012) No. 69 document to meet the needs of product quality testing and research and development experiments. Accreditation of the laboratory shall be carried out in accordance with the GB/T27025 standard (equivalent to the ISO/IEC 17025 Accreditation Criteria for Testing and Calibration Laboratories). Strive to make the testing laboratory the legal testing laboratory for this furnace tube product.
NPA quality control system is strictly in accordance with ISO9001. All production and process inspection can be traced to ensure the effective quality production process and provide reliable quality assurance.
NPA will be equipped with high temperature creep testing machine and scanning electron microscope (SEM), and will become the first manufacturer in China to meet all test requirements for petrochemical high alloy furnace tube.
