The production of storage tanks is mainly divided into the following processes: 1. Material preparation: Select suitable raw materials according to requirements, and cut and cut them. 2. Forming: The raw materials are formed by a rolling machine, and appropriate forming methods (such as circular ring method, flanging method, etc.) should be selected based on the stress situation of the storage tank. 3. Welding: After completing the forming process, welding is carried out. The welding quality directly affects the service life and safety of the storage tank, so it should be strictly operated in accordance with the process requirements. 4. Inspection: Check whether the appearance, size, welds, and airtightness of the storage tank meet the requirements. 5. Surface treatment: Derusting, polishing, spraying and other treatments are carried out on the welding parts and surfaces to ensure a clean and beautiful appearance of the storage tank.
