Читать книгу Fabrication of Metallic Pressure Vessels - Maan H. Jawad - Страница 24

Often decisions about cost of fabrication depend on the quantity of product being produced. Vessels will be more economical to produce if processes are optimized, but sometimes the cost of optimization is not warranted. For a single vessel, or even a small number of vessels, the cost of procuring forming equipment and optimal welding equipment and costs of developing tooling will likely exceed any profit on the job. Sometimes even setting up existing tooling for a vessel will not pay for itself, and it will be less expensive to fabricate the product using less efficient means but with essentially no initial setup cost.
