The world’s largest oil-fired project under construction unit 4 boiler completes the hydraulic pressure test
At 14:57 pm of July 15, 2019, the hydraulic pressure test of unit 4 boiler in Saudi Yanbu phase III Project was completed successfully. And there was no leakage in the total of 39044 welding joints in the heating surface of the boiler.
The boiler hydra test for the primary steam system is super-heater system. During the period of test pressure, the system remained stable, and all the pressure components and valves on the heating surface of the boiler body had no leakage, the pressure components had no deformation, and the process quality and other technical indicators all met the requirements of ASME code.
The success of the unit 4 boiler super-heater hydraulic pressure test laid a solid foundation for the smooth operation of the following project works.
