What is the price of prefabricated polyurethane overhead insulation pipe?

This depends on what main material is used, what insulation method is used, and what outer tube is used. For example, the inner tube adopts 304 thin-walled stainless steel tube, the insulation layer adopts polyurethane foam, and the outer protection tube adopts pe tube. Take DN 16 as an example, the price is generally in 30 yuan/meter. It's just the price of materials, excluding installation fees and freight.
