The prefabricated buried insulation pipe produced by our company has excellent overall performance. The working steel pipe adopts the process of shot blasting and rust removal on the outer surface and corona treatment on the inner surface of the outer protective pipe, further improving the three in one performance of the insulation pipe. 1. The service life can reach 30-50 years, and correct installation and use can greatly reduce the cost of pipeline maintenance. 2. The polyethylene outer protective pipe is made of high-density polyethylene material, which can ensure that the pipe is not damaged by external factors during transportation, installation, and use. 3. The thermal insulation performance is good. The thermal insulation effect is 4 to 9 times higher than that of other thermal insulation pipes, and the heat loss is only 25% of that of traditional pipes. Long term operation can save a lot of energy and significantly reduce the energy cost. The thermal insulation layer is made of rigid polyurethane foam with a density of more than 60 kg/m3, which has good mechanical performance and thermal insulation performance. Generally, it can withstand 120 ℃. By modification or combination with other thermal insulation materials, it can withstand 180 ℃. 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, the outer protective pipe and the insulation layer form a solid whole. This product is widely used in urban centralized heating and cooling projects, energy-saving, easy to install, and has good economic and social benefits.
Our company uses high-performance polyether polyols and multiple methyl polyisocyanates as the main raw materials, which are foamed through chemical reactions under the action of catalysts, foaming agents, surfactants, etc. Its application scope is also becoming more and more extensive, and it is widely used in various pipelines such as heating, cooling, oil and gas transportation due to its simple construction, energy saving and anti-corrosion.
Polyurethane products have excellent characteristics such as light capacity, high strength, thermal insulation, sound insulation, flame retardancy, cold resistance, corrosion resistance, non absorption of water, and easy and fast construction. They have become materials for thermal insulation, waterproofing, sealing, etc. in industrial doors such as construction, transportation, petroleum, chemical, power, refrigeration, etc.
Polyurethane rigid foam pipe) polyurethane tile) (polyurethane pipe): used for insulation and cold insulation of various indoor and outdoor pipelines, central air-conditioning pipelines, chemical, pharmaceutical and other industrial pipelines.
Directly buried prefabricated insulation pipe (pipe in pipe)
The direct buried insulation pipe is composed of a steel pipe for conveying the medium, a high-density polyethylene outer sleeve, a polyurethane rigid foam insulation layer filled between the steel pipe and the outer sleeve, which is tightly bonded.
Directly buried prefabricated insulation pipes have outstanding advantages over traditional insulation pipes: (1) good insulation performance, with heat loss only 25% of traditional pipes, and long-term operation can save a lot of energy, significantly reducing energy costs.
(2) It has strong waterproof and corrosion-resistant capabilities, does not require a pipe trench, can be directly buried underground or in water, and is easy and fast to construct.
(3) It has good corrosion and impact resistance under low temperature conditions and can be directly buried in frozen soil layers.
(4) The service life can reach 30-50 years, and correct installation and use can greatly reduce the cost of pipeline maintenance.
(5) An alarm system can be set up to automatically monitor pipeline leakage faults, accurately indicate the fault location, and automatically sound an alarm. The service life of high-temperature prefabricated buried insulation pipes can reach more than 50 years, which is 3-4 times longer than traditional trench laying and overhead laying. Compared with trench or overhead laying, it has the advantages of saving energy, occupying less land, convenient construction, and beautifying the environment, and has made significant progress in recent years. Not only in the north, but also in high water level areas in the south, it is being widely promoted. It can be seen that polyurethane insulation pipes have strong insulation performance and can ensure that the temperature of the transported material inside is not affected by external changes. They have good cold resistance in winter. The sound insulation performance of polyurethane buried insulation pipes is very good, avoiding the disturbance of liquid flowing through the pipeline during transportation. At the same time, polyurethane direct buried insulation pipes can achieve anti-corrosion and non absorbent properties. Polyurethane insulation pipes allow for unrestricted installation positions and can be used in various locations. The construction of polyurethane buried insulation pipes is simple, fast, efficient, and reduces capital costs. Polyurethane direct buried insulation pipes are used for low heat loss and can save energy.

Polyurethane insulation pipes are used for insulation and cooling engineering of various indoor and outdoor pipelines, central heating pipelines, central air conditioning pipelines, chemical, pharmaceutical and other industrial pipelines. Overview: Polyurethane foam insulation pipe has been rapidly developed as an excellent insulation material since the birth of polyurethane synthetic materials in the 1930s. Its application scope is also becoming more and more extensive. Due to its simple construction, energy saving and anti-corrosion, it is widely used in various pipelines such as heating, cooling, oil transportation, and steam transportation. Widely used in various pipelines for heating, cooling, oil transportation, steam transportation, etc.
