1. Prefabricated directly buried insulated steel pipes do not require the construction of huge trenches. The insulated pipes only need to be buried underground. Therefore, the project area is greatly reduced, which is conducive to environmental protection. It reduces the amount of earthwork excavation by about 50% and reduces the amount of civil engineering work. The construction and concrete content are 90%. At the same time, the construction of insulated pipes and on-site trenching are carried out in parallel, and only on-site joints are needed, which can shorten the construction period by more than 50%.
2. Good thermal insulation performance, heat loss is only 25% of traditional pipes, long-term operation can save a lot of energy and significantly reduce energy costs.

3. It has strong waterproof and corrosion resistance, no need for attached pipe trenches, and can be directly buried in the ground or water. The construction is simple and fast, and the overall cost is low.
4. It also has good corrosion resistance and impact resistance under low temperature conditions, and can be directly buried in underground frozen soil.
5. The service life can reach 30-50 years. Correct installation and use can make the maintenance cost of the pipe network extremely low.
6. An alarm system can be set up to automatically detect leakage faults in the pipe network, accurately indicate the fault location and automatically alarm.
