Anticorrosion insulating thermal energy transfer pipe
Advantages:
Excellent insulation properties. It losts only 25% heat of traditional pipe and can save a lot of energy to reduce energy costs significantly in long distance transport..
Strong waterproof and corrosion resistance. It can be directly buried in the ground or water without attached trench so it makes the construction rapid and simple, integrated cost low.
Good corrosion resistance and impact resistance at low temperature. It can be directly buried in the frozen earth.
Long service life. Its working life can reach at least 50 years.The correct installation and use can make the cost of pipe maintenance low.
Alarm system. Alarm system automatically detects pipe leakage failure and accurately indicates fault location and automatically alarms.
Features
Under 350°C centrifugally glass-wool is an excellent heat insulting material because it is light in weight, steady in geometric configuration and its physical properties and geometric configuration can be completely recovered after drying rain. This characteristic brings about great convenience to the construction and reduces the construction cost because the pipe can be adapted to high groundwater level conditions. Anticorrosion coating of the steel pipe selected to use is silicone resin heat-resistant paint(rating of temperature≥400°C ) which effectively prevents the corrosion of steel and prolongs its service life.
Good characteristics such as high strength and better tightness of the steel sleeve successfully solve the problems of waterproof and anti-leak.
PE film or triple PE cold–tangled belt is selected to seal the ports of the pipes in the integral structure to prevent the entering of humidity before installation or water under construction.
Multilayer staggered joints wrap of centrifugally glass-wool heat insulating material can effectively reduces the loss of heat and at the same time control the temperature of the coat surface under 50°C.So it can protect the anticorrosive coating and prolong the lifetime of the pipe. Application of steam line in the high water level regions possesses great functions of steam resistance, moisture discharge and corrosion resistance. The centrifugally glass-wool we choose is from Owens Corning. It has moderate steam resistance which has been approved by many authorities
Special materials are taken to use in heat insulation methods of sliding support and internal fixation in the steam pipes which prevent the production of heat channel so as to guarantee the temperature control of the wrap anticorrosive coating.
Multilayer of aluminum-based heat-reflective layers can be wrapped on the heat insulating materials of the steam pipe which can effectively reduce the loss of heat and make the steam pipe more economic. Anticorrosion coating and cathodic protection can be both adopted to protect the outside steel and the anticorrosion life will be largely increased.
External protecting pipe of filament-wound glass-reinforced plastics has moderate rigidity and water impervious. It can be suited to various complicated soil environments because of its excellent anticorrosion property.
Draining system is enclosed totally with advantages of layout flexibility, rational construction and safety.
Moisture-discharging pipes on the steel sleevings can not only discharge the humidity immediately but also be used as the alarm signal pipes in daily operation.
Instrument used in heat compensation of steam pipe heat preservation is the excellent weave type compensator which is installed in the annular pipe in direct burial type with no need to set observation well, easily to operate and short in construction time.
