en.Wedoany.com Reported - The hydrostatic test of Boiler No. 2 at the Tianmen Thermal Power Project of SPIC Integrated Smart Energy Branch was successfully completed on the first attempt. This marks another milestone for the project following the success of the first boiler's hydrostatic test. The test lasted 14 hours, with pressure rising to 18.375 MPa and holding for 20 minutes, during which no pressure drop occurred, confirming that the boiler's main installation quality fully meets standards.

The hydrostatic test is a critical step in verifying boiler installation quality. By applying a static water pressure higher than the working pressure to pressure-bearing components, it comprehensively validates equipment manufacturing and welding quality. During this test, tens of thousands of welds on all heating surface tube banks, headers, steam-water pipes, and valves of Boiler No. 2 showed no leakage under overpressure conditions, with no residual deformation in pressure-bearing components, and technical indicators exceeding code requirements. From equipment hoisting to welding operations, the Thermal Power Division of the Integrated Smart Energy Branch implemented full-element quality control and full-process welding quality management, achieving a 100% pass rate for all welds.

Currently, both boilers of the Tianmen Thermal Power Project have entered the insulation and auxiliary equipment installation phase, while work on the third boiler is progressing as planned. The Integrated Smart Energy Branch is advancing subsequent construction to ensure all three boilers are commissioned on schedule this year, providing thermal power support for Tianmen City.
