On June 15, 2026, the first special training course on valve maintenance for mechanical operation and maintenance staff of PipeChina Eastern Crude Oil Storage & Transportation Co., Ltd., undertaken by Chengdu Chenggao Valve Co., Ltd. and Chengdu Chengfeng Valve Co., Ltd., came to a successful end. The 14-day training integrated theoretical lectures with practical operation drills throughout the whole course.

       Featuring both professionalism and practicality, the training curriculum covered structural principles of mainstream valves including gate valves, ball valves, plug valves and pressure relief valves, as well as core skills such as filling in and reviewing DEC valve data sheets, valve fault troubleshooting and emergency response. Adopting a combined model of theoretical explanation, on-site demonstration and hands-on practice, the training delivered immersive teaching with professional teaching aids to comprehensively consolidate the professional capabilities of all participants.

       The learning outcomes were assessed through a comprehensive evaluation combining written theoretical exams and multiple practical operation assessments. All participants studied diligently and practiced hard, successfully completing all assessment items and fully achieving the training objectives.

       This training not only helped improve the competence of mechanical operation and maintenance personnel of the partner enterprise, but also fully demonstrated our company’s comprehensive strength in valve R&D, manufacturing, maintenance and technical services. Going forward, Chenggao Valve will continue to leverage its technical advantages, deepen industrial exchanges and cooperation, and strive for joint progress and integrated development together with partners.
