More than DEG C, the average percentage of water loss of pipe network system is about 3%.Owing to fluid loss is big, heat is lost serious, an almost all of secondary net,
The hydraulic misadjustment problem of secondary network all various degrees, cannot science regulate again owing to pipe network is aging, therefore heating enterprise
For hankering being difficult to ensure that the heating quality of user.
In decades, central heating cause is the development construction in China city and the raising of living standards of the people is made that weight
Big contribution.The most large-area central heating network is aging, seriously corroded has become as the outstanding problem affecting central heating, sternly
Heavily threaten city for thermally safe and common people orthobiosis.
Implementing central heating network transformation has been the task of top priority carrying out city heat supply work.Can be significantly by pipe network improving
Reduce the evaporating, emitting, dripping or leaking of liquid or gas of pipe network, reduce energy resource consumption and save the energy, improve energy utilization rate；Heat supply can be made to look forward to by pipe network improving
Sparetime university's amount uses of the new technology, new technology, improves the science regulating power of heating enterprise, improves overall heat supply level；Pass through pipe network
Transformation can General Promotion heating system safety and heat supply supportability, improve constantly the use thermal mass of numerous residents, benefit
The common people.Implementing central heating network transformation is the act benefited the nation and the people, and early implements early to be benefited.
Implementing central heating network improvement project, emphasis removes waste and old heat supply pipeline exactly, lays the new pipeline of heat supply, and this needs
Put into huge fund.How to accomplish to utilize existing pipeline, maybe can lay less or thinner pipeline, only spend less
Investment, equally reaches the heating load needed？This is design and the construction problem often thought deeply of scientific worker.
