Jiusheng Offshore has established a closed-loop quality acceptance system covering the whole construction process and all working procedures. It covers key processes including process pressure testing of pipelines, thickness measurement of anti-corrosion coatings on steel structures, pipeline internal inspection, weld acceptance of large-bore boiler pipelines, installation of high-pressure valve systems, dimensional measurement of furnace structures, thermal insulation patrol inspection and position verification of heating surface tube panels.

     Multi-party witnessing, visual inspection, dimensional measurement and joint random appearance sampling are implemented for every construction step. Equipped with professional testing instruments and standardized acceptance procedures, the company carries out strict layer-by-layer quality control from raw materials to finished components, fully complying with construction quality standards for power engineering, and laying a solid quality foundation for the long-term safe and stable operation of projects.
