Imported 304 stainless steel pipes are used in the inner layer to ensure that they are not rusted, scaled and polluted during operation.

_The middle high density polyurethane foaming insulation layer is made of imported high quality rigid polyurethane fully automatic high pressure equipment. The data has low thermal conductivity and good thermal insulation performance. In winter, the temperature difference between day and night is only about 1 ~2, when the 300-meter pipeline network operates normally at 75 C hot water. It has excellent thermal insulation.

High strength PVC/PE pipe is used in the outer shell maintenance layer. Anti-ultraviolet, anti-aging and durable, not affected by biological and chemical corrosion, avoiding the invasion of external water, air and bacteria, greatly preventing the destruction of external elements on the insulation pipe data. It not only guarantees the thermal insulation effect, but also prevents the chagrin of periodic maintenance of thermal insulation data. It can ensure that the service life of the whole pipe reaches more than 50 years.

The product integrates three kinds of high-quality data into one. The disposable device is in place, the laying is convenient, and the construction period of the device is shortened, thus saving the operation cost and the construction cost of the device.

1. Waterproof and anticorrosion performance is strong, can be directly buried in open or water, and traditional types of insulation pipes should be attached with trenches, so that the project is cumbersome, shorten the time and reduce the cost.

2. The service life of polyurethane insulation pipe is longer. After testing, the service life of polyurethane insulation pipe is as long as 30-50 years, which greatly reduces the cost of pipeline network replacement or repair.

3. Thermal insulation performance is becoming more prominent. Data show that the thermal loss of polyurethane insulation pipe is only 25% of the traditional insulation pipe material, which can save a lot of energy, but also significantly reduce the cost.

4. Good impact resistance can be directly buried in open permafrost.

5. It has good mechanical energy and adiabatic performance, and can withstand up to 100 C under normal conditions.

6, rigid polyurethane foam, fully filled the gap between the steel pipe and the casing, has a certain bonding strength, making the steel pipe, the outer tube machine storage layer three constitute a solid whole, not easy to leave.

7. An alarm system can be set up, which can accurately indicate the exact location of the fault and automatically alarm, greatly improving the efficiency of maintenance and ensuring the safe operation of the pipeline.
