1. Reduce project cost. According to the estimation of relevant departments, the double pipe heating pipeline can generally reduce the project cost by about 25% (using glass fiber reinforced plastic as the protective layer) and 10% (using high-density polyethylene as the protective layer). 2. Low heat loss and energy saving. The thermal conductivity of prefabricated directly buried insulation pipe is λ=0.013-0.03kcal/m? hoC， It is much lower than other commonly used pipeline insulation materials in the past, and the insulation effect is improved by 4~9 times. Moreover, its water absorption is very low, about 0.2kg/m2. The reason of low water absorption is that the closed cell rate of polyurethane foam is up to 92%

Polyurethane rigid foam thermal insulation material for construction industry is an important branch of polyurethane industry, which is characterized by multiple uses of one material, as well as thermal insulation, waterproof and other functions. This kind of product has a history of 40 years since it was applied in the European construction industry in the 1960s, and polyurethane has also been used as a thermal insulation and waterproof material in the construction industry through legislation. In recent years, with the development of China's building market, polyurethane rigid foam insulation products have been widely used in the field of building insulation and waterproofing, and have become one of the insulation products in the main market. The inner layer of insulation material is wrapped on the inner steel pipe with microporous calcium silicate staggered joints, and the gaps are filled with high temperature insulation and high elasticity protection

Performance advantages: The directly buried thermal insulation pipeline has the characteristics of heat preservation, waterproof, anti-corrosion, thermal insulation, sound insulation, flame retardant, cold resistance, anti-corrosion, light capacity, high strength, simple and fast construction, and is not afraid of plant root thorns. It has become an indispensable material for thermal insulation, waterproof plugging, sealing and other industrial sectors such as construction, transportation, petroleum, chemical, power, refrigeration, etc. The directly buried thermal insulation pipe is used for thermal insulation, cold insulation, oil pipeline, steam transmission and other pipeline projects of indoor and outdoor pipelines, central heating pipelines, central air-conditioning pipelines, chemical, pharmaceutical and other industrial pipelines.

Polyurethane directly buried insulation pipes are also called prefabricated insulation pipes, which are divided into two types: plastic sheathed steel insulation pipes (high-density polyethylene directly buried insulation pipes) and steel sheathed steel insulation pipes (high-temperature steam insulation pipes). Plastic sheathed steel insulation pipe is made of high-density polyethylene outer pipe, polyurethane foam insulation layer and inner working steel pipe, or the insulation layer is changed into aerogel insulation felt and polyurethane high-pressure foam composite scheme. The steel sheathed steel insulation pipe is composed of external protective steel pipe plus steel pipe anti-corrosion, polyurethane foam insulation layer and internal working steel pipe, or aerogel insulation felt plus polyurethane high-pressure foaming composite scheme. High temperature prefabricated directly buried insulation pipe not only has traditional trench

Compared with the traditional steel pipe insulation method, the prefabricated directly buried thermal insulation steel pipe has very prominent advantages: 1. The prefabricated directly buried thermal insulation steel pipe does not need to build huge trenches, only need to bury the thermal insulation pipe underground, so it greatly reduces the project land occupation, is conducive to environmental protection, reduces the amount of earthwork excavation by more than 50%, and reduces the amount of civil masonry and concrete by 90%. At the same time, insulation pipe construction and on-site trenching are carried out in parallel, and the construction period can be shortened by more than 50% with only on-site joints. 2. Good thermal insulation performance, heat loss is only 25% of that of traditional pipes, long-term operation can save a lot of energy and significantly reduce energy costs. 3. With strong

The classification methods of polyurethane insulation pipes are very complex. Generally, there are several ways according to people's habits. 1. According to the temperature of its transmission medium, it can be divided into: normal temperature polyurethane directly buried insulation pipes, high-temperature polyurethane directly buried insulation pipes, and cryogenic polyurethane directly buried insulation pipes; 2. According to the difference of the outer protective layer, it can be divided into: FRP outer protective layer polyurethane directly buried insulation pipe, high-density polyethylene outer protective layer polyurethane directly buried insulation pipe, steel outer protective layer polyurethane directly buried insulation pipe and other outer protective layer directly buried insulation pipe; 3. There are many kinds of transportation media: polyurethane prefabricated insulation pipes for water supply, high-temperature polyurethane insulation pipes, and steam transportation

The heat loss of polyurethane insulation pipe is only 25% of that of traditional pipes. Long term operation can save a lot of energy and significantly reduce energy costs. Anticorrosive and thermal insulation steel pipes have strong waterproof and corrosion resistance. They can be directly buried in the ground or water without the need for pipe trenches. The construction is simple and rapid. The insulated steel pipe also has good corrosion resistance and impact resistance under low temperature conditions, and can be directly buried in the underground frozen soil. The service life of anti-corrosion and thermal insulation steel pipe can reach 30-50 years. Correct installation and use can reduce the maintenance cost of pipe network. Anticorrosion and thermal insulation steel pipe can be equipped with an alarm system to automatically detect the leakage fault of the pipe network, accurately indicate the fault location and automatically alarm
