Quotation for pressure vessel manufacturing
Thread Content
For the quotation on pressure vessel manufacturing, is it appropriate to calculate it in this way? Class I carbon steel: material cost * 2; Class II carbon steel: material cost * 2.2; Class III carbon steel: material cost * 3
The container type, purpose, and so on also need to be considered
Carbon steel x2.5, stainless steel and other expensive materials around x1.7
Factors such as the proportion of forgings and pipes in the equipment, as well as the complexity of the equipment (the difficulty of manufacturing it), all influence the cost of the equipment; it is not advisable to rely solely on such calculations
It is best to develop software for calculating costs in the chemical industry: 1. Design costs, 2. Material costs, 3. Processing costs, 4. Inspection costs, 5. Transportation and packaging costs, 6. Profit
