Structural characteristics of steel jacket steel insulation pipe
1. The rolling bracket fixed on the inner working steel pipe is used to rub against the inner wall of the outer casing, and the thermal insulation material moves along with the working steel pipe, so that there will be no mechanical wear and pulverization of the thermal insulation material.
2. The jacket steel pipe has high strength and good sealing performance, which can be effectively waterproof and impermeable.
3. The outer wall of the jacketed steel pipe adopts high-quality anti-corrosion treatment, so that the life of the anti-corrosion layer of the jacketed steel pipe is more than 20 years.
4. The insulation layer of the working steel pipe is made of high-quality insulation material, which has a good insulation effect.
5. There is a gap of about 10~20mm between the insulation layer of the working steel pipe and the outer steel pipe, which can play a role in further heat preservation. It is also the extremely smooth moisture drainage channel of the directly buried pipeline, so that the moisture drainage tube can really play the role of timely moisture drainage, and at the same time play the role of a signal tube; or pump it into a low vacuum, which can more effectively keep heat and reduce the temperature inside the outer casing. wall corrosion.
6. The rolling bracket of the working steel pipe is made of special low thermal conductivity material, and the friction coefficient with the steel is about 0.1, and the frictional resistance of the pipeline is small during operation.
7. The fixed bracket of the working steel pipe, the connection between the rolling bracket and the working steel pipe adopts a special design, which can effectively prevent the generation of pipeline thermal bridges.
8. The drainage of the directly buried pipeline adopts a fully sealed structure, and the drainage pipe is connected to the low point of the working steel pipe or the position required by the design, and there is no need to set up an inspection well.
9. The elbows, tees, bellows compensators, and valves of the working steel pipe are all arranged in the steel casing, and the entire working pipeline runs in a fully sealed environment, which is safe and reliable.
10. The use of internal fixation support technology can completely cancel the external fixation of concrete buttresses. Save costs and shorten the construction period.
Steel jacket steel insulation pipe insulation structure
External sliding type: the thermal insulation structure is composed of working steel pipe, glass wool thermal insulation layer, aluminum foil reflective layer, stainless steel fastening belt, sliding guide bracket, air insulation layer, outer protective steel pipe, and outer anti-corrosion layer.
Anti-corrosion layer: protect the outer steel pipe from corrosive substances to corrode the steel pipe and prolong the service life of the steel pipe.
External protective steel pipe: protect the insulation layer from groundwater erosion, support the working pipe and withstand certain external loads, and ensure the normal operation of the working pipe.
What are the uses of steel jacket steel insulation pipe
Mainly used for steam heating.
Steel-sheathed steel direct-buried thermal insulation pipe (steel-sheathed steel direct-buried laying technology) is a waterproof, leak-proof, impermeable, pressure-resistant and fully-enclosed buried technology. A major breakthrough in regional use. It is composed of a steel pipe for conveying medium, an anti-corrosion jacket steel pipe, and ultra-fine glass wool filled between the steel pipe and the jacket steel pipe.
