Abstract
The utility model relates to an anti-high temperature epoxy organic silicone anti-corrosion layer thermal insulation pipe, comprising a steel pipe, a preformed welding sect, an anti-high temperature epoxy organic silicone anti-corrosion layer, a soft mineral wool insulating layer and a mental plastic sleeve. The anti-high temperature epoxy organic silicone anti-corrosion layer has excellent anti-heat performance and can resist 350 DEG C, the soft mineral wool insulating layer has fine waterproof and heat-insulating performance and can be applied to heat insulating pipe line for transmitting high temperature medium.
Description
The utility model relates to a kind of thermal insulation pipe of fire resistant epoxy organosilicon anticorrosive coat, can be used for carrying the hot insulated line of high temperature media.
Have the hot insulated line of carrying high temperature media now, its corrosion-inhibiting coating is easy under 250～300 ℃ of high temperature media effects to be produced decomposition, peel and steel pipe is corroded; The outer protective layer of existing soak pipeline adopts Steel Sleeve easily to produce the burn into perforation, makes the thermal insulation layer infiltration.
The purpose of this utility model is to avoid above-mentioned deficiency of the prior art and provides a kind of and be used for the soak pipeline, has the thermal insulation pipe of the fire resistant epoxy organosilicon anticorrosive coat of good resistance to high temperature, Corrosion Protection.
The purpose of this utility model can reach by following measure.
The thermal insulation pipe of fire resistant epoxy organosilicon anticorrosive coat of the present utility model, the reservation welding section 2 that comprises steel pipe 1, steel pipe 1 two ends, it is characterized in that having fire resistant epoxy organosilicon anticorrosive coat 3, soft rock wool heat-preservation layer 4, steel to mould sleeve pipe 5 in turn at the outer surface of steel pipe 1, fire resistant epoxy organosilicon anticorrosive coat 3 is made up of the solidfied material of 1 weight portion epoxy silicone resin, 0.3～1 weight portion iron oxide red, 0.3～1 weight portion French chalk, 0.3～1 weight portion mica flour, 0.3～2 weight portion polyurethane.
Be 12m, external diameter of pipe 377mm, wall thickness 8mm for the length of steel pipe 1 preferably, the every end of length of reserving welding section 2 respectively is 100mm, the thickness of fire resistant epoxy organosilicon anticorrosive coat 3 is 100 μ m, the length that steel is moulded sleeve pipe 5 is 11.8m, external diameter of pipe is 625mm, wall thickness 8mm, fire resistant epoxy organosilicon anticorrosive coat 3 is made up of the solidfied material of 1 weight portion epoxy silicone resin, 0.6 weight portion iron oxide red, 0.3 weight portion French chalk, 0.3 weight portion mica flour, 0.5 weight portion polyurethane.
The thermal insulation pipe manufacture process of fire resistant epoxy organosilicon anticorrosive coat is as follows:
With the outer surface derusting by sandblasting of steel pipe 1, spraying fire resistant epoxy organosilicon anticorrosive coat 3, put in the outside of steel pipe 1 that steel is moulded sleeve pipe 5, the annular space moulded between the sleeve pipe 5 at steel pipe 1 and steel adds soft rock wool heat-preservation layer 4.Steel is moulded sleeve pipe 5 and can be carried out dip-coating with the polypropylene plastics that the steel pipe inner and outer surface immerses hot melt and form.
The utility model compared with prior art has following advantage:
1, the thermal insulation pipe of fire resistant epoxy organosilicon anticorrosive coat, wherein fire resistant epoxy organosilicon anticorrosive coat 3 has good heatproof degree variation performance, resistance to heat, oxidation resistent susceptibility, can anti-350 ℃ of high temperature.
2, soft rock wool heat-preservation layer 4 has good resistance to high temperature, thermal insulation property, and easy construction can reduce cost.
3, steel is moulded sleeve pipe 5 and is had superior corrosion resistance energy, barrier propterty, makes the repaired mouth operation easy.
Below in conjunction with description of drawings.
Fig. 1 is the longitudinal sectional drawing of the thermal insulation pipe of fire resistant epoxy organosilicon anticorrosive coat;
Fig. 2 is its transverse cross-sectional view.
Among the figure: the 1-steel pipe; 2-reserves welding section; 3-fire resistant epoxy organosilicon anticorrosive coat; The soft rock wool heat-preservation layer of 4-; The 5-steel is moulded sleeve pipe.
