What is thermal insulation steel pipe?

Heat preservation pipe is a steel pipe that is processed by heat preservation technology to ensure that the internal temperature and surface temperature of the working steel pipe meet or meet the requirements of use under the action of different working environments and external media.

Insulation pipes are widely used in liquid and gas transmission pipe networks, chemical pipeline insulation projects in petroleum, chemical, central heating and heating networks, central air-conditioning ventilation pipes, municipal engineering, etc.

Compared with the traditional steel pipe insulation method, the prefabricated direct-buried thermal insulation steel pipe has very prominent advantages:
1. The prefabricated direct-buried thermal insulation steel pipe does not need to build huge trenches, and only needs to bury the thermal insulation pipe underground, thus greatly reducing the land occupation of the project, which is conducive to environmental protection, reducing the amount of earthwork excavation by more than 50%, and reducing the amount of civil construction and masonry. 90% of construction and concrete. At the same time, the construction of the insulation pipe and the on-site trenching are carried out in parallel, and only on-site joints are required, which can shorten the construction period by more than 50%.
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. It has strong waterproof and corrosion resistance, no need for additional 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, and the 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.
