Application and development of the new thermal insulation pipe

更新日期:2013-06-07  浏览:1551

Polyurethane thermal insulation pipe is the transmission medium, which is composed by the working pipe, foam insulation, polyethylene plastic outer protective tube in the order from outside to inside.

Polyurethane thermal insulation pipe now available in market has obvious advantages compared with the general thermal insulation pipe, first of all, the lower the price of polyurethane pipe insulation, thereby reducing the project cost; secondly, low heat loss and save energy; Again, anti-corrosion, iron and steel materials insulation performance long life; Finally, small footprint, fast construction, favorable environmental protection, safety performance is much better than the average thermal insulation pipe.

People now know polyurethane thermal insulation pipe, which is advance a lot than traditional trench and overhead pipeline and the performance of which is more practical, bring convenience to people at the same time, also it has brought the obvious social benefit and economic benefit. At the same time it also provides a strong technical support for energy-saving measures and encouraged for the nation.

With the development of thermal insulation pipe,thermal expansion pipe  there are more and more new thermal insulation pipe, such as: high temperature of prefabricated directly buried insulating pipe, which is mainly composed of four parts. First, steel pipe: the use of welded steel pipe spiral submerged arc welded steel pipe, seamless steel pipe, double-sided according to the requirement of transmission medium technology. Second, the insulation layer: the use of rigid polyurethane foam. Third, the protection shell: high density polyethylene or glass steel. Fourth, the leakage alarm line: manufacturing high temperature of prefabricated directly buried insulating pipe, probing pipe the insulating layer near the pipe, buried with a warning line, once the pipeline leakage somewhere, conduction through the warning line, it can sound an alarm in the special detecting instrument and shows accurate position and the size of the leakage of water leakage in time.
