Advanced technologies are fully employed in the construction of Guangdong Petrochemical projects to create a “zero-leakage factory”!

Thread Content

Guangdong Petrochemical Company strictly implements the requirements set by CNPC Group, adopting torque-controlled tightening technology throughout the production preparation phase of its integrated refining and chemical processing projects, in order to create \"leakage-free devices\" and a \"leakage-free factory\". At present, the company has organized various production departments to form torque-controlled fastening task forces; professional third-party supervision agencies have arrived at the plant, and the installations related to sulfur recovery that are in the flange installation phase have begun operations on a full scale. 90% of leaks in petroleum refining and chemical plants occur at the flange sealing surfaces. The constant torque tightening technique involves calculating the bolt torque value under a cold pre-tightening condition, and then using hydraulic torque wrenches or hydraulic tensioning fittings to tighten the flanges in a uniform and precise manner. Compared with traditional manual tightening, it offers advantages such as improved reliability of static sealing, elimination of the need for thermal tightening processes, and better protection for workers. This approach can **reduce the risk of leaks in refining and chemical processing units, eliminate VOC emissions from flanges, and lay the foundation for long-term operation of these units. Furthermore, Guangdong Petrochemical carries out insulation work immediately after completing the pressure testing of all valves and flanges, which significantly reduces the construction time and will provide technical support for the timely commissioning of the entire project. The overall progress of the Guangdong Petrochemical Integration project has reached 70%
