Overview

Prefabricated insulation pipe made of polyurethane foam plastic in Xinghua City Steel pipe and polyethylene outer protective pipe of insulation pipe used for central heating, cooling and hot oil transmission and distribution are closely combined with polyurethane foam insulation materials. The diameter range is 90～ 1240. The full name of the insulation pipe is high-density polyethylene polyurethane rigid foam foam insulation pipe. Its function is to protect the temperature of the fluid inside the work pipe, prevent heat transfer with the outside world, and cause the loss of fluid temperature.

Introduction of polyurethane foam prefabricated insulation pipe in Xinghua City

1,Low thermal conductivity was used,Hard polyurethane with good thermal insulation performance as insulation material,Has excellent thermal insulation properties.
2,After normal operation130Transportation of water at ℃40When kilometers away,Cooling is only for1Around ℃.
3,Has strong waterproof and corrosion-resistant capabilities,No need to attach a pipe trench,Can be directly buried underground or in water,Construction is simple and fast.

4,It also has good corrosion resistance and impact resistance under low temperature conditions,It can be directly buried in the frozen soil layer.
5,Prefabricated insulation pipes are made of corrosion-resistant materials（HDPEHigh density polyethylene outer sleeve,Not affected by biological and chemical corrosion.
6,Can be provided according to user needsDN20~DN1200Pipes of various diameters and insulation thicknesses, as well as matching fittings (elbows),three-way,reducer,Fixed sections, etc

7,To ensure the trinity of prefabricated buried insulation pipes,Shot blasting treatment on the outer surface of the steel pipe before foaming,Electric corona treatment on the inner surface of plastic pipes,The rust removal grade has reachedGB/T 8923-1998ChineseSa2.5The regulations,The surface tension inside the shell tube reaches50dyne/Centimeters.
8,The outer protective tube of polyethylene is made of high-density polyethylene material,Made with various additives such as antioxidants,And the technical requirements for the outer protective tube of the directly buried raw material pipe,Improved the overall quality of the outer protective tube. The specific technical indicators are shown in the table below.
Insulation materials are used for various types of cold water,air conditioning,Circular cold oil pipeline,Insulation for pipes of irregular shapes and any form. Prevent condensation: Polyethylene foam pipe material is a closed cell structure,It relies on gas insulation inside the closed cell instead of polyethylene material to achieve insulation. It has excellent resistance to water vapor infiltration. Built in vapor barrier formed,It is both an insulation layer and a vapor barrier layer,No additional vapor barrier is required. The wet resistance factor ц value is much higher than other insulation materials. It can effectively prevent condensation from occurring.

Composition of insulation pipe:
（1）Working steel pipe: Welded steel pipes are used according to the technical requirements of the conveying medium,seamless steel pipe,Double sided submerged arc spiral welded steel pipe. （2）Insulation layer: Made of hard material. （3）Protective shell: Made of high-density polyethylene or fiberglass. （4）Leakage alarm line: When manufacturing high-temperature prefabricated buried insulation pipes,In the insulation layer near the steel pipe,Buried with alarm lines,Once there is a leak in a certain part of the pipeline,Through the transmission of alarm lines,Report the alarm and display the accurate location and degree of water leakage,In order to notify maintenance personnel to quickly handle the leaking pipe section,Ensure the safe operation of the heating network.
