Pressure vessel quotation
Thread Content
What coefficients are generally used by various manufacturers to quote prices for the various components of pressure vessels? Why can there be such large differences in prices for equipment from the same batch?
The quote is determined based on factors such as the difficulty level of the container, the unit price of materials, auxiliary materials, transportation costs, testing fees, labor costs, taxes, machine usage time, and profit. Since the cost of materials is transparent, the manufacturing costs vary depending on the version; the differences lie in transportation costs and profit amounts. For conventional pressure vessels, if the manufacturing units chosen have similar capabilities, the prices will not differ much. However, when comparing large state-owned enterprises with private enterprises, the cost difference is quite significant
It is more appropriate to determine the price by taking into account factors such as the difficulty level of the container, the unit cost of materials, auxiliary materials, transportation costs, testing fees, labor costs, taxes, machine usage time, and profit
It is still common to quote based on experience, such as by converting the price per ton
The costs of materials, production, etc. are relatively transparent; what remains is the profit, which depends on whether you have the capability to earn it. A low bid doesn’t necessarily mean winning.
The situation varies from factory to factory; even when it comes to bidding, some bidders are from outside the area while others are local, and that affects the transportation costs. The technical levels of different factories vary, but the price of conventional container materials is fixed, as are the processing costs; if there’s a significant difference, it’s considered fraud
““The quote is determined by taking into account factors such as the difficulty level of the container, the unit price of materials, auxiliary materials, transportation costs, testing fees, labor costs, taxes, machine usage time, and profit.” To be precise, this can actually only be considered as an estimation of cost! Because by the time you’ve finished calculating all of this, you think you’ve included everything that should be included, but it often doesn’t reflect market conditions. In fact, in this industry these days, bids are usually won on the basis of the lowest price; so it’s not about how much you want to earn, but rather about determining the minimum amount you need to earn in order to take on a project! Among those factors determining the price, there are two key ones: 1. Shipping costs: It’s somewhat better for regular containers, as the costs are more or less the same in that case ； It’s mainly equipment with a diameter of over 3 meters; often, the shipping cost alone can differ by hundreds of thousands. 2. Profit: It is the lowest amount you can afford after deducting expenses; of course, more would be better. The other elements are basically transparent; it’s similar across the whole country! Personal opinion, for reference only!
Quotation budget: raw material costs + consumables (welding rods, welding wire, oxygen, acetylene, etc.) + costs related to technical requirements (design, supervision, inspection, etc.) + labor costs + external processing fees + taxes + profit
Generally quoted per ton, 13,000/t
Thank you all for your help, which has expanded my knowledge. But I wonder what it would be if all the material costs were taken into account. Exactly what multiplier should be used? Should it be 2, 2.5, or 3? How do ordinary pressure vessel manufacturers quote prices? I hope to get everyone's help. It’s best to give an example. Please send it to my QQ email: 673984071. Thank you!
