  • steel surface preparation

  • Generally, the building area temperature of the steel surface preparation should be considered before the tank design and construction. The temperature in the steel surface preparation building area is closely related to the evaporation loss, energy loss, storage tank materials and the selection of detection instruments, or has a direct impact on the storage cost of the storage liquid. For the same medium, the higher the air temperature and the longer the duration, the higher the material temperature in the steel surface preparation, the higher the corresponding pressure and the more volatile loss.
