Official statistics show that the annual supply of steam in Hefei reached 3.6 million tons and generated 630 million tons of electricity. The main steam pipe network was 493 kilometers in length with 378 residential and commercial services and 179 residential areas with an area of over 115,000 heating units 24.5 million square meters. It is predicted that this winter another 10% more than last year's increase in the number of users. Therefore, to prevent all types of hidden dangers of heat pipe network risk, so that millions of households can be assured.

In the past, the detection department mainly used GPS positioning, non-destructive testing and other technical means, and with the help of manpower to the entire city tube The net begins with a carpet-type review and inspection, which may not have to be so tiring later. It is understood that the project plans to set pressure and temperature monitoring points 214, hot water and steam pipe soil Temperature sensor monitoring point 211.

Among them, the pressure and temperature equipment is mainly used to monitor the pressure and temperature in the steam pipe. The pressure sensor monitoring equipment is installed on the pipe in the water tank, and the safety level of the pipe is analyzed according to the data of two adjacent pressure monitoring equipment.

Temperature monitoring equipment can also monitor the hydrophobic tank hydrophobic temperature, according to the temperature curve to determine the total hydrophobic and hydrophobic frequency, in order to determine the amount of water within the pipeline. Next to the pipelines, soil temperature sensors can be buried to conduct analysis based on real-time data, and if the temperature exceeds a certain limit, there is a certain safety risk on the pipeline.

Through the establishment of the heat pipe network safety operation monitoring system, the steam pipe network can finally achieve real-time monitoring of the operating pressure of the steam pipe network, real-time monitoring of the pressure, flow and temperature of the hot water pipe network. The monitoring data can be sent to Hefei City Lifeline Safety Operation Monitoring Center, and share to Hefei Thermal Power Group.
