At 11:52 AM on June 4, 2025, exciting news came from the site of the Henan Puyang Purun Thermal Power Project: "#2 boiler pressure raised to 14.16 MPa!", "Pressure stable for 20 minutes with no drop; all system equipment shows no deformation, normal expansion, valves tightly closed, pressure unchanged; metal walls and welds of pressure-bearing components show no deformation or leakage!", "Boiler hydrostatic test successful at first attempt!" Jubilation filled the project site. This achievement not only signifies the smooth attainment of a crucial milestone node for the project but also fully demonstrates CWPC's exceptional strength and superior quality in boiler manufacturing, once again earning high praise from the project owner.

To ensure the hydrostatic test succeeded at the first attempt, the company's on-site technical service personnel actively cooperated with the owner, Installation Company and other relevant units. They organized multiple in-depth discussions to meticulously analyze existing problems and challenges, and vigorously promoted on-site installation work until all conditions met the requirements for the hydrostatic test. The boiler design pressure is 11.33 MPa, with the overpressure test pressure at 14.16 MPa. During the test, all parties strictly followed the plan, precisely controlled the test results, perfectly met the specification requirements, and received unanimous recognition from all sides.

The first-time success of this hydrostatic test not only lays a solid foundation for subsequent work such as boiler chemical cleaning, steam blowing, and steam turbine roll-off commissioning but also highlights CWPC's outstanding manufacturing processes and quality control capabilities. Leveraging advanced technology, stringent quality standards, and a professional service team, CWPC ensures the high quality and performance of its boiler products, winning the owner's high recognition and solidifying the foundation for future cooperation between the two parties. CWPC will continue to uphold the "customer-centric" philosophy, providing the owner with higher-quality products and services, facilitating smooth project progress, and jointly creating a brighter future.
