  • The product name: Supply pipe insulation
  • Product number: F006
  • Detailed

product description:

I produced prefabricated buried pipe insulation, overall performance, strict implementation of standard CJ / T114-2000 standards, work steel pipe outer surface shot blasting process and an outer protective tube surface corona treatment process to further improve the insulation pipe Trinity properties.

product structure:

Structure of high-density polyethylene foam polyurethane prefabricated buried insulating pipe products: the steel work, polyurethane rigid foam insulation and low high-density polyethylene outer tube closely together.


1, the service life of up to 30 - 50 years, proper installation and use can make the pipe network maintenance costs low.2, polyethylene outer sheath tube made of high-density polyethylene material, it can ensure the pipes are not affected by external factors in the transportation, installation and use and cause damage.

3, good insulation properties, thermal insulation effect than other insulation increase 4-9 times and the heat loss is only 25% of the traditional pipe, long run can save a lot of energy, significantly reduce energy costs, insulation material density greater than 60 / m3 rigid polyurethane foams, having good mechanical properties and thermal insulation properties, usually can be temperature 120 ℃, by modification or in combination with other insulation materials can be temperature 180 ℃.

Foam sufficient to fill the gap between the pipe and the outer protective tube, and has a certain viscosity, the steel pipe, tube and the outer jacket insulation layer three form a solid whole. The products are widely used in urban central heating and refrigeration engineering, energy-saving effect is remarkable, easy construction and installation, with good economic and social benefits.

4, highly waterproof and corrosion resistance, without laying pipe trench can be directly buried in the ground or water, simple and rapid construction, and lower total cost, small footprint.5, at low temperatures also have good corrosion resistance and impact resistance, it can be directly buried permafrost.
