The heat exchanger for the Three-Ring Overhaul Project of the Sixth Engineering Project Department was successfully hoisted and installed.

3 On October 18, with the joint efforts of the project team, the No. 6 Engineering Project Department successfully installed the 39 series heat exchanger for the Sanhuan overhaul project.

To ensure the success of the lifting operation, the project department started preparations three days in advance, making meticulous arrangements and deployments, from crane selection to the selection of lifting equipment. At 8 am, two cranes arrived, and the lifting operation officially began. The project department implemented closed management of the operating area, with guards and supervisors in place at all entrances and exits, and work permits and lifting slings and equipment ready. After four hours of debugging, the main crane's operating conditions were adjusted to the optimal state. With the roar of the crane engine, the old heat exchanger slowly rose under everyone's watchful eyes, landed safely, and two hours later, the new heat exchanger was successfully installed.

The successful replacement of the heat exchanger has been praised by Yunnan Phosphate Group Haikou Phosphate Co., Ltd., laying a solid foundation for the company to further deepen its cooperation with Yunnan Phosphate Group Haikou Phosphate Co., Ltd. [Sixth Engineering Project Department/Gao Zhiwen]
