Through the composition of prefabricated directly buried insulation pipe, the insulation pipe is composed of steel, fiberglass reinforced plastic sheath and fiberglass reinforced plastic shell, which is characterized by: the smooth insulation layer also contains high temperature resistant insulation layer and elastic sealing layer. This is a new and practical method to deal with the problems of heat preservation, sliding, smoothness and real pipe waterproof of the prefabricated directly buried heat preservation pipe used in urban central heating at 130 ℃ to 600 ℃.
In addition to China, the high-temperature prefabricated directly buried insulation pipe is equipped with a leakage alarm line. Once the pipe leaks, the alarm line after conduction can appear in the leakage of water in the insulation pipe of special detection instrument, the exact location and invasive standard of leakage. In order to inform the inspectors to deal with the leaking pipe quickly and ensure the safe operation of the heating pipe network. Hindus, who produce insulation pipes, set leakage alarms at the end of the pipes to fill the vacuum.
Ordinary prefabricated direct buried insulation pipe is mainly used for gas transmission pipeline, chemical pipeline insulation engineering, petroleum, chemical industry, central heating pipe network, central air conditioning ventilation pipe, municipal engineering, etc. Direct buried heat preservation pipe is a kind of pipe with good heat preservation performance, stable performance and low engineering cost. The prefabricated direct buried insulation pipe is used to deal with the heat loss of urban central heating under the high temperature of 130 ℃ to 600 ℃. The insulation of the prefabricated direct buried insulation pipe, the smooth slideway and the waterproof of the pipe body are the problems.
The direct buried heat preservation pipe not only has the advanced technology and applicable functions which are difficult to be compared with traditional cooking and excluding laying pipes, but also has significant social and economic benefits, and is also a powerful countermeasure for heating. The selection of directly buried heating pipeline prefabricated directly buried heat preservation pipe indicates that the development of heating pipeline technology in China is still at a new starting point. And in the use of prefabricated direct buried insulation pipe has come back, the development prospects will be more broad.
The above is the detailed introduction of Jinan insulation pipe to the development prospect of directly buried insulation pipe. For more information, please click https://www.sdhpgy.com
