Product details

Prefabricated steam heat pipe is made of medium steel pipe and steel pipe and steel pipe, anti-corrosion coat coat between steel tube filled superfine glass wool, also can use graphite, silicon calcium clay pipe shell and filling polyurethane foam composite。 Steel casing set of steel (steel) embedding technology is a kind of waterproof, leakproof, impermeability, resistance to pressure and totally enclosed embedding technology, directly buried installation is technology in high underground water level using a major breakthrough。 Steel bushing steel steam heat preservation is the chief problem of the protection of the steel tube strict waterproof reliability, in addition to have good mechanical strength, casing because of the high strength steel welding connection, waterproof sealing performance reliability is very high, in addition, the high temperature resistant performance is also can't be matched by other external protecting tube。 In the area of high water level, in order to ensure that the underground water does not affect the normal operation of the pipe, the outer protective layer is used for the solid and closed steel pipe shell。

The structure of precast steam insulated pipe is divided into different sliding modes: internal sliding type and external sliding type.

1, sliding inside: thermal insulation structure by working steel tube, aluminum silicate, drag reduction, microporous calcium silicate, insulating layer, stainless steel fastening tape, aluminum foil reflector, polyurethane thermal insulation layer, coat steel pipe, external anticorrosive coating.

2, outside sliding type: thermal insulation structure by working steel tube, glass wool insulation layer, aluminum foil reflector, tighten belt, stainless steel sliding guide bracket, air thermal insulation layer, protecting steel tube, external anticorrosive coating。

Structure mechanism of precast steam insulated pipe:

1. Anticorrosive layer: protect the outer steel pipe to avoid corrosion of the steel pipe, and extend the life of steel pipe.

2. External protective steel pipe: protect the insulation layer from groundwater erosion, support the working tube and can withstand certain external loads to ensure the normal work of the work pipe.

3. Polyurethane foam layer: ensure the temperature of the medium and maintain the surface of the outer sheath to maintain normal temperature.

4. Barrier and reflector: ensure that the organic foam material does not enter the inorganic refractory high temperature layer; Reflect the heat in the high temperature layer.

5。 Inorganic hard insulation layer: high temperature resistance, ensure the interface temperature between the organic insulation layer and ensure that foam is not carbonized。

6. Drag reduction layer: ensure that the working steel tube expands and shrinks the free movement.

7。 Working steel pipe: ensure normal flow of conveying medium。

The precast steam insulated pipe is composed of internal working steel pipe, outer protective steel pipe and intermediate insulation layer。 Working steel pipe is sprayed with two coats of anti-rust paint。 The insulation layer is composed of high-temperature fiber felt, ultra-light porous calcium silicate insulating tiles and polyurethane foam plastics。 The coated steel pipe is coated with sand blasting and then wound with six layers of glass fiber and resin corrosion coating。

Characteristics of precast steam insulated pipe:

1. Waterproof and moisture-proof.

2, resistant to high temperature and high pressure, suitable medium temperature 350 ℃, pressure is 2。5 Mpa。

3. Low heat consumption and better insulation effect than any traditional heat preservation method.

5。 Long service life can reach 30 to 50 years。

Prefabricated steam thermal insulation pipe protection is the first problem of reliability of tight waterproof, in addition to have good mechanical strength, casing because of the high strength steel welding connection, waterproof sealing performance reliability is very high, in addition, the high temperature resistant performance is also can't be matched by other external protecting tube.
