Abstract
The invention discloses a steel-in-steel directly buried steam heat insulating pipe and relates to the technical field of heat insulating pipes. The steel-in-steel directly buried steam heat insulating pipe comprises an inner steel pipe, an outer steel pipe and a heat insulating layer which is arranged between the inner steel pipe and the outer steel pipe in an injecting molding mode, wherein the top of the outer steel pipe is uniformly provided with heat insulating material filling holes and lifting rings, heat insulating material air bubble discharging holes are formed between the adjacent heat insulating material filling holes, and the heat insulating material filling holes and the heat insulating material air bubble discharging holes are sealed in a repair welding mode after injection molding is finished. By arranging the heat insulating material filling holes, a molten heat insulating material is filled in a gap between the inner steel pipe and the outer steel pipe; through the heat insulating material bubble discharging holes, air bubbles in the heat insulating material are discharged, so that the occurrence of pores in the heat insulating layer due to the existence of the air bubbles is avoided; and at the same time, by arranging the lifting rings, the large heat insulating pipe can be conveniently transported and mounted by using mechanical equipment.
Description
Technical field：
The present invention relates to insulating tube technical field, and in particular to a kind of steel sleeve steel direct buried steam pipeline.
Background technology：
At present, common direct buried steam pipeline is made up of working steel tube, foam heat-insulation layer and vinyon outer protection tube.This
Plant the thermal losses that direct buried steam pipeline can be substantially reduced in steam course of conveying, save energy, but external polyethylene plastics
The bearing of outer protection tube is limited, easily occurs metaboly after direct-burried, base insulating layer is extruded, so as to affect heat insulation effect and guarantor
The service life of warm pipe.For this case, our company develops a kind of steel sleeve steel direct buried steam pipeline, not only heat insulation effect
Significantly, and it is unlikely to deform, so as to ensure that base insulating layer gives full play to heat insulation effect.
The content of the invention：
The technical problem to be solved is to provide a kind of high insulating effect and the steel sleeve steel of long service life is straight
Bury steam insulation pipe.
The technical problem to be solved is realized using following technical scheme：
A kind of steel sleeve steel direct buried steam pipeline, including interior steel pipe, outer steel pipe and by injection molding manner be located at interior steel pipe with
Heat-insulation layer between outer steel pipe, the outer steel pipe top is uniformly provided with insulation material hand-hole and hoisting ring, adjacent insulation material
Insulation material air bubble discharge hole is provided between hand-hole, the insulation material hand-hole and insulation material air bubble discharge hole are in injection
After the completion of be closed by repair welding form.
The outer outer wall of steel pipe and interior steel pipe inner wall are equipped with anticorrosive coat.
The invention has the beneficial effects as follows：The present invention is injected the insulation material for melting by the setting of insulation material hand-hole
To in the space between interior steel pipe and outer steel pipe；And discharged in the bubble in insulation material by insulation material air bubble discharge hole,
Avoid making occur space inside heat-insulation layer because of the presence of bubble；Simultaneously by the setting of hoisting ring, it is easy to utilize plant equipment
Carry and large insulation pipe is installed, so as to the service life for saving manpower He greatly prolong insulating tube.

Specific embodiment：
In order that technological means, creation characteristic, reached purpose and effect that the present invention is realized are easy to understand, tie below
Conjunction is specifically illustrating, and the present invention is expanded on further.
As shown in Figure 1, 2, 3, a kind of steel sleeve steel direct buried steam pipeline, including interior steel pipe 1, outer steel pipe 2 and by injection
Mode is located at the heat-insulation layer 3 between interior steel pipe and outer steel pipe, and outer steel pipe top is uniformly provided with insulation material hand-hole 4 and hoisting ring
5, insulation material air bubble discharge hole 6, insulation material hand-hole and insulation material bubble are provided between adjacent insulation material hand-hole
Tap is closed after the completion of injection by repair welding form, and outer outer wall of steel pipe and interior steel pipe inner wall are equipped with anticorrosive coat 7.
The general principle and principal character and advantages of the present invention of the present invention has been shown and described above.The technology of the industry
Personnel it should be appreciated that the present invention is not restricted to the described embodiments, the simply explanation described in above-described embodiment and specification this
The principle of invention, without departing from the spirit and scope of the present invention, the present invention also has various changes and modifications, these changes
Change and improvement is both fallen within scope of the claimed invention.The claimed scope of the invention by appending claims and its
Equivalent thereof.
