How to estimate the costs for chemical corrosion protection?
Thread Content
A plant-wide anti-corrosion plan is being prepared, covering equipment, pipelines, frames, and ladders. . . . . . The leader wants to know the approximate cost; how should it be estimated? This post was last edited by frankqe on 2008-3-4 11:48]
One kilogram of paint can provide corrosion protection for 3 square meters; do the math, and then add the labor cost.
The anti-corrosion treatment for equipment and pipelines is generally calculated based on surface area, while for steel structures such as frames and ladders, it is usually calculated based on weight； First, count the number of equipment units that require anti-corrosion treatment as well as the total length of pipes. Then, calculate the required amount for each piece of equipment based on its surface area, and do the same for pipes of different diameters. Create a spreadsheet that lists the device identifiers, pipe numbers, and the area that needs anti-corrosion treatment. Include information on the different materials to be used for anti-corrosion purposes. Following the standard construction requirements of applying two coats of primer and two coats of topcoat, using an average paint consumption of 200 g/m2, and adding in the costs related to labor (such as rust removal, painting, and auxiliary materials), it is possible to estimate the workload initially ； The steel structure method is similar to the one described above, except that it is calculated based on weight. There is a standard conversion relationship between weight and surface area, which can be referred to in the relevant specifications.
I’m also very curious to know if there’s any information available on the quotas for anti-corrosion measures
The quotas vary from province to province; it’s best to consult the local authorities for details.
A simple way is to find a professional anti-corrosion company, provide them with the details of what anti-corrosion measures are needed, have them prepare a budget, and then you can review it.
Reply to the post on floor 3: Thank you! !
To prepare an estimate for anti-corrosion measures across the entire plant, it is first necessary to know the general anti-corrosion approach. By estimating the area that needs anti-corrosion treatment on the equipment and large pipelines, as well as the weight of the steel structures, and then applying the unit cost for anti-corrosion measures, an approximate cost can be determined!
