What is the difference between polyurethane insulation pipe and prefabricated steel sleeve steel insulation pipe
Difference between polyurethane insulation pipe and prefabricated steel sleeve steel insulation pipe:
Polyurethane insulation pipe is made of polyethylene as the outer protective layer, which is called yellow jacket by the industry. Its structure is composed of three parts: outer protective layer, thermal insulation layer and anti leakage layer. The outer protective layer is made of polyethylene jacket pipe, glass fiber reinforced plastic or other materials.
The outer protective pipe of steel sheathed steel insulation pipe is steel pipe. Steel pipe for external protection: protect the insulation layer from groundwater erosion, support the working pipe and bear certain external load to ensure the normal operation of the working pipe.
Polyurethane insulation Guan Dingyi: polyurethane insulation pipe, full name: high-density polyethylene plastic external protective polyurethane foam prefabricated directly buried insulation pipe, from conveying medium, work pipe, polyurethane insulation layer, polyethylene plastic external protection tube, through the equipment in turn combined.
Polyurethane heat preservation pipe is used for heat preservation and cold preservation of various indoor and outdoor pipelines, hot spring water project, central heating pipeline, central air conditioning pipeline, chemical industry pipeline, etc!
Since polyurethane foam insulation pipe was born in 1930s, it has been developed rapidly as an excellent thermal insulation material, and its application scope is more and more extensive. Because of its simple construction, energy-saving and anti-corrosion effect, it is widely used in various kinds of heating, refrigeration, oil transportation, steam transmission and other pipelines.
Definition of prefabricated steel sheathed steel insulation pipe:
It is composed of working steel pipe, glass wool thermal insulation layer, aluminum foil reflective layer, stainless steel fastening belt, sliding guide bracket, air thermal insulation layer, external steel pipe and external anti-corrosion layer, which are successively combined outward through the equipment.
According to the calculation of relevant departments, the double-layer heating pipeline can generally reduce the project cost by about 25% (with FRP as the protective layer) and 10% (with HDPE as the protective layer).
