Key determinants of manufacturing cost for spherical storage tanks in Dalian

As an important storage equipment in the industrial field, the manufacturing cost of Dalian spherical storage tanks is influenced by various factors.

Material costs are the top priority. The choice of material for the main body of the tank is very important, and the price difference of steel with different materials is significant. For example, high-strength alloy steel has excellent performance, can withstand high pressure, and can make the tank wall relatively thin, saving material consumption, but it is expensive; Although ordinary carbon steel is affordable, in order to meet the strength requirements, the tank wall needs to be thicker, resulting in an increase in material weight and cost. At the same time, the quality and price of valve, flange and other accessory materials cannot be ignored. If the storage medium is corrosive, using special materials such as corrosion-resistant stainless steel will significantly increase the cost of accessories.

The manufacturing process cost has a significant impact. In terms of molding process, the segmented assembly method has high flexibility but requires a large amount of welding work, high technical requirements for welders, high consumption of welding materials, and high labor costs; Although the integral stamping method can ensure the quality of the sphere, it requires large stamping equipment, which incurs high costs for equipment procurement, maintenance, and operation, and is limited by the size specifications of the tank body. In terms of welding process, high-quality welding relies on equipment and technology. For example, automatic welding equipment requires a large investment, and non-destructive testing after welding also increases costs. The surface treatment process is equally critical. If the storage tank is used for special media or environments, such as food and drug storage or outdoor anti-corrosion, using high-quality anti-corrosion coatings or lining materials will increase the total cost due to the material cost and complex construction process.

Design and engineering management costs are indispensable. A professional design team conducts precise design based on factors such as storage medium properties, pressure, temperature, and volume. Complex design requirements will increase design costs. In engineering management, tasks such as progress control, quality supervision, and safety management require the investment of manpower and material resources. The salaries of management personnel, office expenses, and the purchase and use of quality testing equipment constitute the cost of engineering management. The protective measures taken to ensure construction safety will also increase expenses.

The transportation and installation costs should not be underestimated. The transportation of large spherical storage tanks in Dalian requires special tools, and transportation distance, road conditions, and possible renovation costs can all affect transportation costs. The lifting and debugging processes during the installation process require high technical and equipment requirements, and the costs of labor and equipment rental further increase the total cost. In short, the manufacturing cost of spherical storage tanks is the result of multiple factors such as materials, processes, design management, and transportation and installation.
