[0002] Insulated pipe is the abbreviation of insulated pipe. Insulated pipe is used for the transportation of liquid, gas and other media. It is used in the insulation projects of pipelines in petroleum, chemical industry, central heating, central air conditioning, municipal engineering, etc. Insulated pipe has strong corrosion resistance and waterproof ability, and the overall cost is low. The outer protective layer is usually wrapped with anti-corrosion coating or plastic casing and other materials. The anti-corrosion coating needs to be sprayed, brushed and other processes to ensure that it fits tightly with the pipe surface.
