Plastic-coated Drum

The heating temperature of the storage tank should be determined based on the organic chemical properties of the steel and its bending stiffness. The higher the carbon content of the steel and the more other aluminum alloy elements, the greater the bending stiffness during operation, and the higher the required heating temperature. Welding sequence for electric welding. For materials and welding standards with the same welding characteristics, if the welding sequence differs, the tendency for thermal cracking also varies. This is due to other welding stresses caused by different electric welding sequences. To significantly reduce welding stresses, an effective welding sequence needs to be established.
