Polyurethane direct buried thermal insulation tube pushes new technology to save 100 degrees per ton

The company's three-in-one direct-buried insulation pipe produced by the imported high-pressure complete polyurethane foaming equipment has excellent overall performance, strictly performs the rust removal treatment of the outer surface of the steel pipe and the corona treatment process on the inner surface of the outer pipe, thereby further improving the bonding performance of the insulation pipe. The insulation layer material is a rigid polyurethane foam with a density of 60kg/m3 to 80kg/m3, which fully fills the gap between the steel pipe and the casing, and has a certain bonding strength, so that the steel pipe, the outer casing and the insulation layer are Form a solid whole. Polyurethane foam has good mechanical properties and thermal insulation properties. It can usually withstand temperatures of 120 ° C. It can be temperature-resistant to 180 ° C by modification or combination with other insulation materials. Directly buried prefabricated insulation pipes have outstanding advantages over traditional insulation pipes:

1. The heat preservation performance is good, and the heat loss is only 25% of the traditional pipe. The long-term operation can save a lot of energy and significantly reduce the energy cost.

2, has a strong waterproof and corrosion resistance, no need to attach pipe trenches, can be directly buried in the ground or water, construction is simple and rapid, the overall cost is low.

3. It also has good corrosion resistance and impact resistance under low temperature conditions, and can be directly buried in underground frozen soil.

4, the service life can reach 30-50 years, the correct installation and use can make the maintenance cost of the pipe network extremely low.

5. The alarm system can be set to automatically detect the leakage of the pipe network, accurately indicate the fault location and automatically alarm.

The polyurethane insulated steel pipe has a "two-step method" and is composed of a high-density polyethylene outer protective layer, a polyurethane rigid foam plastic pipe and a steel pipe. The insulation layer material is a rigid polyurethane foam with a density of 60kg/m3 to 80kg/m3, which fully fills the gap between the steel pipe and the casing, and has a certain bonding strength, so that the steel pipe, the outer casing and the insulation layer are Form a solid whole. Polyurethane insulation steel pipe foam has good mechanical properties and thermal insulation properties. Generally, it can withstand temperature of 120 ° C by modification or combination with other insulation materials to withstand temperature of 180 ° C.
