Storage tank fabrication is a complex project, and each step needs to be made accurately to ensure the integrity and usability of the final product. Today, we will list the approximate steps of storage tank fabrication.

Step 1: Design And Planning

Before the storage tank fabrication, detailed design and planning are required. Engineers will develop a detailed design plan based on factors such as the material and purpose of the tank, the characteristics of the storage medium and the storage conditions. This includes determining the structure, size, shape, material selection, etc. of the tank. The final product of the tank must not only meet customer needs, but also follow industry specifications.

Step 2: Material Preparation

After the design is completed, it is necessary to prepare the materials required for the manufacturing process. The main materials of the tank generally include carbon steel or stainless steel, pipes and various auxiliary materials. It is best to choose materials that are corrosion-resistant, high-temperature-resistant, high-pressure-resistant, cold-resistant and heat-resistant, so that they can be used for most storage media and meet the needs of most customers.

Step 3: Cutting And Forming

After the materials are prepared, the cutting and forming stage begins. According to the requirements of the design drawings, workers use tools such as cold cutting machines to cut carbon steel or stainless steel materials into various required shapes and sizes. After cutting, the materials are processed by bending, curling and other processes to form the tank body, bottom plate, top cover and other components.

Step 4: Welding Process

After cutting, welding is done. Welding is not only to connect the plates together, but also to ensure the sealing of the tank.

In the welding process, large enterprises usually use automated pipeline welding machines, and small enterprises mostly use manual welding. Manual welding requires welders to have superb skills and rich experience, and each weld point must be carefully polished and inspected. Automatic welding uses advanced welding robots to ensure that the weld is uniform, beautiful and non-destructive, while greatly improving efficiency and quality. The most common welding methods are argon arc welding, gas shielded welding and submerged arc welding. Each welding method has different applicable scenarios and can be selected according to needs.

Step 5: Inspection And Testing

After the tank is welded, it needs to undergo strict inspection before it can be considered completed. Generally, non-destructive testing, pressure testing, sealing testing, etc. are carried out. These detection methods can effectively detect defects such as tiny cracks, pores and scratches in the weld to ensure that the tank will not leak or explode in actual use.

Step 6: Coating And Anti-corrosion

Anti-corrosion treatment is required to ensure that the tank can be shipped. In order to extend the service life of the tank, a layer of anti-corrosion coating is usually sprayed on the surface of the tank to prevent the tank from corrosion and oxidation. Depending on the stored material, an inner lining of anti-corrosion materials may also be required to further enhance the corrosion resistance of the tank.

Through the above steps, a safe and reliable tank can be truly produced. From design to finished product, every link requires fine operation and strict control. In particular, the welding process is the most critical step in storage tank fabrication.
