Questions regarding the anti-corrosion and insulation of process pipelines
Thread Content
I’m a beginner seeking advice from those with more experience: 1. Does anyone have information on the standards for calculating anti-corrosion and insulation requirements? I have some ideas about how to carry out these calculations, but they probably don’t meet the design specifications. For example, how is the area required for pipe anti-corrosion calculated? Should the pipes and fittings be calculated separately or as a whole based on their length? Where can I find this information? 2. Regarding the dimensions of the thermal insulation rock wool, the values given in the material specifications are D273/333, D219/280, and D168/228. What do these values mean? I couldn’t find any information about them even by searching on Baidu; it’s quite frustrating
For the algorithms related to heat preservation and corrosion prevention, you need to check the local pricing standards. Fittings are of course priced separately, with completely different costs. 273/333, D219/280, D168/228 indicate the tube shell, inner diameter/outer diameter.
D273/333, D219/280, and D168/228 refer to the dimensions of the thermal insulation rock wool; I’m not quite sure about this. Does rock wool also have inner and outer diameters?
Rock wool tube shells – you can search on Baidu to find out what tube shells are
D273/333, D219/280, and D168/228 are the dimensions of the insulation casing. The numbers listed earlier represent the outer diameter of the insulation tube: 273 (10”), 219 (8”), etc. Then, depending on the desired thickness of the insulation layer, select a tube shell that meets the requirements
