1. The thermal insulation performance of polyurethane foam pipe is good, and the heat loss is only 25% of that of traditional pipes, which can save a lot of energy and significantly reduce energy costs during long-term operation.
2. The polyurethane foam pipe has strong waterproof and corrosion resistance, and can be directly buried in the ground or water without the need for a pipe trench, which is simple and rapid in construction and low in comprehensive cost.
3. The polyurethane foam tube also has good corrosion resistance and impact resistance under low temperature conditions, and can be directly buried in the underground frozen soil.
4. The service life of polyurethane foam pipe can reach 30-50 years, and the correct installation and use can make the maintenance cost of the pipe network very low.
5. The alarm system can be set up for the polyurethane foam pipe, which can automatically detect the leakage fault of the pipe network, accurately indicate the fault location and automatically alarm.

1.Low heat loss and energy saving. Because the directly buried pipe is insulated by polyurethane rigid foam, its thermal conductivity value is not greater than that in the state of 50, which is much lower than other commonly used insulation materials in the past, and the thermal insulation effect is increased by 4-9 times; The water absorption rate is very low, approximately; The closed cell rate of polyurethane foam is as high as about 88%; Coupled with the insulation layer and the high-density polyethylene protective shell with good waterproof performance outside, it changes the situation of "wearing wet cotton jackets" of traditional trench laying heating pipes, and greatly reduces the overall heat loss of heating pipes.
2.Anti-corrosion, good insulation performance and long service life. Because the polyurethane rigid foam insulation layer is tightly bonded to the outer skin of the steel pipe, the directly buried insulation pipe isolates the penetration of air and water, and can play a good anti-corrosion role.
High-density polyethylene enclosures have good corrosion protection, insulation and mechanical properties. The service life is 3-4 times higher than that of traditional trench laying and overhead laying. 3.
It occupies less land and is fast in construction, which is conducive to environmental protection. The directly buried heating pipeline does not need to build a huge trench, but only needs the insulation pipe to be buried in the ground, so it greatly reduces the land occupation of the project, reduces the amount of land excavation, and shortens the construction period. 4.
Once the leakage occurs somewhere in the pipeline, through the conduction of the alarm line, the accurate location of the water seepage and leakage of the insulation pipe can be displayed on the special detection instrument table, so as to facilitate the seepage detection personnel to quickly deal with the leaking pipe section and ensure the safe operation of the heating pipe network.

Jupeng [direct sales] polyurethane foam insulation pipe factory is better.
The full name of polyurethane insulation pipe is high-density polyethylene plastic outer protection polyurethane foam prefabricated directly buried insulation pipe, which is composed of working steel pipe, polyurethane insulation layer and polyethylene plastic outer protection pipe of the conveying medium, which is formed by the laughter liquid equipment in turn, which is a kind of industrial insulation pipe, which is composed of three layers of protective layer, insulation layer and anti-leakage layer.
Polyurethane insulation pipe has the characteristics of high cost performance, low heat loss, anti-corrosion, good insulation performance, long service life, convenient construction and operation, simple maintenance, and does not occupy space. Polyurethane insulation pipes are widely used in industrial shengzhou pure production, such as liquid and gas transportation pipe networks, chemical pipelines, thermal insulation projects, petroleum, central heating networks, air conditioning and ventilation pipes, municipal engineering, etc., which can prevent heat loss and pipeline rupture.
Application of PU products in the furniture industry:
In the furniture industry, imitation wood material is one of the main application directions of polyurethane rigid foam, imitation wood material is light in quality and density, strength is equivalent to wood, the use of this material to manufacture furniture, not only will not appear cracks after molding, but also reduce the cost of manufacturing.
China's furniture industry is still to expand domestic demand, stimulate urban consumption, with the tightening of China's real estate policy, the construction of affordable housing and low-rent housing will continue to accelerate, China's furniture industry will not be impacted, the public's demand for polyurethane will grow at a rate of 5 per year.
At present, the best insulation material for the exterior wall of domestic buildings is polyurethane foam. >>>More
