Prefabricated polyurethane insulation pipe, high-density polyethylene outer protective pipe, supports customized drawings

Description :

　　The raw materials for yellow jacket insulation pipes mainly include seamless steel pipes and seamless steel pipes. The commonly used thermal insulation material of yellow jacket polyurethane thermal insulation steel pipe is rigid polyurethane foam plastic, and the applicable temperature is -185~120 ℃. This material has a soft texture. To improve its strength, a high-density polyethylene layer is added outside the insulation layer to form a composite structure to prevent groundwater from seeping into the insulation layer. The structure of the yellow jacket insulation pipe mainly includes a working steel pipe layer, a polyurethane insulation layer, and a high-density polyethylene protective layer. The outer layer is covered with black or yellow polyethylene plastic material prefabricated to a certain wall thickness. Black ones are called black jacket insulation pipes, while yellow ones are called yellow jacket insulation pipes. Its functions are twofold: firstly, to protect the polyurethane insulation layer from mechanical damage caused by hard objects; secondly, to prevent corrosion and waterproofing. High density polyethylene polyurethane foam insulation steel pipes shall comply with the SY/T114-2000 and SY/T115-2001 standards.

　　The sound insulation performance of polyurethane foam insulation pipe is very good, avoiding the noise of liquid flowing through the pipeline during transportation and disturbing the public. The polyurethane insulation pipe is composed of working steel pipe, rigid polyurethane foam plastic insulation layer and high-density polyethylene outer protective pipe. The polyethylene outer protective pipe is made of high-density polyethylene material, which can prevent the pipe from being damaged by external factors during transportation, installation and use. The insulation material is rigid polyurethane foam with a density of more than 60 kg/m3. The foam can fully fill the gap between the steel pipe and the outer protective pipe, and has a certain viscosity, so that the steel pipe, jacket and insulation layer form a solid whole. This product is widely used inUrban centralized heating and cooling engineeringThe energy-saving effect is significant, the construction and installation are convenient, and it has good economic and social benefits. Execution standard: Prefabricated directly buried insulation pipes made by heating insulation steel pipe manufacturers are popular for their good performance, convenient construction, and long service life (30-50 years). Their structure consists of three parts: outer protective layer, insulation layer, and anti leakage layer. The outer protective layer material is polyethylene sandwich pipe or fiberglass or other materials. There are three types of laying methods: direct burial, overhead, and trench laying.
