Polyurethane anti-corrosion hard insulation pipe

Prefabricated buried insulation and anti-corrosion pipelines refer to composite pipes that are coated with anti-corrosion, insulation, and compression layers on the outer wall of steel pipes. It has the characteristics of low heat loss, strong compressive performance, and good anti-corrosion and waterproof performance. Especially suitable for areas with high groundwater levels. Compared with traditional trench laying pipelines, it has a series of advantages such as good insulation performance, anti-corrosion, good insulation performance, long service life, easy construction and installation, small footprint, and low engineering cost. It has been widely used in centralized heating, oil transportation, chemical industry, refrigeration, and water supply projects in high-altitude areas.

Polyurethane direct buried insulation pipe is a type of prefabricated insulation pipe with good insulation performance, safety and reliability, and low engineering cost.

Directly buried insulation pipes not only have the technical and practical performance of traditional trench and overhead pipeline laying, but also have significant social and economic benefits, and are also powerful measures for heating energy conservation.

High temperature prefabricated buried insulation pipes have excellent anti-corrosion effects due to the tight bonding of the polyurethane insulation layer to the outer skin of the steel pipe, which isolates the entry of air and water. All of its foam holes are closed, and its water absorption is very low. The high-density polyethylene shell and fiberglass shell both have outstanding anti-corrosion, insulation, and mechanical functions. Therefore, the outer skin of the homework steel pipe is difficult to be corroded by external air and water. As long as the water quality inside the pipeline is treated well, according to foreign materials, 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. Polyurethane composite materials have the characteristics of precise foaming, good mobility, sufficient toughness, and high strength. The tolerance of physical properties can meet various production process requirements of customers, and are suitable for various specifications and models of polyurethane prefabricated buried insulation pipes. On polyurethane buried insulation pipes, the density is evenly distributed and the construction is still in compliance with low temperature conditions. The special type can withstand low temperatures of minus 200 ℃ for a long time. Precautions for polyurethane prefabricated directly buried thermal insulation pipe: in the production process of polyurethane prefabricated directly buried thermal insulation pipe, the polyurethane combination polyether and isocyanate must be accurately weighed in strict accordance with the ratio required by the product copy sheet, and the materials must be fully stirred evenly, otherwise the function of polyurethane foam will be affected. When storing, it is necessary to seal it tightly to prevent the escape of foaming agent and the entry of water vapor. It should be placed in a dark, dry, cool, and well ventilated place, avoiding heat sources and being cautious of exposure to sunlight.

One of the great benefits of polyurethane insulation pipes is their energy-saving aspect. Indeed, this influential effect is very good. When using such materials, it is difficult for heat to be directly dissipated from the inside. Therefore, this typical effect is very satisfying for people to use them better, and the influence of this mode is still very good.

Polyurethane 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.
