Carbon steel drum
All plates of the carbon steel drum of the flaker of our company are q345-b, and the plate thickness is determined according to the model and size of the flaker. Except for the two ends of the drum, there is no weld in the radial direction and only one weld in the axial direction. Ultrasonic flaw detection is adopted for the weld. Stress removal treatment is carried out after welding, and 0.1MPa pressure test is carried out to ensure that the weld has no leakage. The surface of the drum is treated with "U" spiral groove, which greatly reduces the thermal stress and deformation caused by the large temperature difference between the outer surface and the inner surface of the drum, and greatly improves the service life of the drum.
