Polyurethane insulation pipe

The manufacturer of seamless polyurethane insulation pipes in Zhengzhou, Henan provides a quotation. Seamless insulation pipes have good insulation performance and significantly reduce energy costs. Pipe insulation compound is used to prepare pipe insulation polyurethane foam. The product consists of two components: black and white. The white material component is composed of various additives such as polyols, catalysts, foaming agents, etc., combined in a stoichiometric ratio. The black material component is poly (toluene) and poly (isocyanates). Directly applicable for on-site foaming, can be mechanically poured or manually applied

　　Polyurethane jacket insulation pipeDefinition and Development Prospects

Polyurethane insulation, also known as "jacket pipe", is composed of high-density polyethylene outer protective layer, polyurethane rigid foam plastic pipe and steel pipe. The insulation layer is made of rigid polyurethane foam with a density of 60kg/m3 to 80kg/m3, which can fully fill the gap between the steel pipe and the casing, and has a certain bonding strength, so that the steel pipe, the casing and the insulation layer form a solid whole. The polyurethane directly buried insulation pipe foam has good mechanical properties and thermal insulation properties. Generally, it can withstand 120 ℃. By modification or combination with other insulation materials, it can withstand 180 ℃. Polyurethane jacket tube has become a relatively mature technology in some developed countries abroad. In the past decade, China's heating engineering technicians have been promoting the development of domestic pipeline laying technology to a higher level by digesting and absorbing this technology. The practical achievements over the past decade have fully demonstrated that the laying method of polyurethane insulated buried pipes has many advantages compared to traditional trench and overhead laying. The directly buried thermal insulation pipe is composed of steel pipe conveying medium, high-density polyethylene outer sleeve, and rigid polyurethane foam insulation layer between the steel pipe and the outer sleeve. This is precisely why polyurethane insulated buried pipes are used in heating projects in China.
