Heating Surface System Hydrostatic Test

Heating Surface System Hydrostatic Test

     Conduct closed-loop pressure boosting and withstand tests on the complete boiler heating surface system. This serves as the core pressure-bearing acceptance procedure before unit commissioning, providing a one-time inspection of weld joint strength and overall tightness for water walls, headers, and main pipelines. Carry out staged pressure holding observations throughout the test, confirm zero leakage and deformation on tube walls, welds, and flanges, and verify that the pressure-bearing structure meets the standards for long-term high-temperature and high-pressure operating conditions.
