Abstract

The utility model discloses a heat preservation pipeline which comprises an inner pipe, a heat preservation layer and an outer pipe. The heat preservation pipeline is characterized in that the inner pipe is wrapped by the heat preservation layer, the heat preservation layer is further wrapped by the outer pipe, and the outer pipe is a steel belt reinforcement corrugated pipe. According to the heat preservation pipeline, due to the fact that the outer surface of the heat preservation layer is wrapped by the steel belt reinforcement corrugated pipe, the good protection effect is achieved, the structural strength of the whole heat preservation pipeline is improved, the impact resistance is high, the internal heat preservation layer is not prone to damage, and the service life of the heat preservation pipeline is prolonged.

Description

A kind of insulation pipe
Technical field
The utility model relates to conveyance conduit, relates in particular to a kind of insulation pipe.
Background technique
Thermal insulation pipe is the abbreviation of insulated piping, and thermal insulation pipe is for the conveying of liquid, gas and other media, in the adiabatic heat-insulation engineering of the pipelines such as oil, chemical industry, space flight, military affairs, central heat supply, central air-conditioner, municipal administration.The outer insulating structure of existing thermal insulation pipe adopts the additional polyethylene protective layer of rigid foam conventionally, and the structural strength of this kind of insulating structure is poor, easily in the time being subject to external influence power, producing and breaks, thereby lose heat insulation effect.
Model utility content
The technical assignment of technical problem to be solved in the utility model and proposition is that prior art is improved, and a kind of insulation pipe is provided, and solves insulation pipe structure intensity difference traditional in current technology, easily breaks and loses the problem of heat insulation effect.
For solving above technical problem, the technical solution of the utility model is:
A kind of insulation pipe, comprises inner tube, thermal insulation layer and outer tube, it is characterized in that, described inner tube is wrapped up by thermal insulation layer, is also enclosed with outer tube in the outside of thermal insulation layer, and described outer tube adopts steel strip reinforced bellows.The utility model improves traditional insulation pipe structure; outside at thermal insulation layer is coated with steel strip reinforced bellows; the ring stiffness of steel strip reinforced bellows is strong, good airproof performance; the effectively inner thermal insulation layer of protection; avoid thermal insulation layer to be damaged; thereby effectively guarantee the thermal insulation property of insulation pipe, improved the working life of thermal insulation pipe.The structure of steel strip reinforced bellows is light-duty simultaneously, with respect to install the mode of steel pipe increase structural strength outward additional at thermal insulation layer for, the utility model can too much not increase the weight of insulation pipe in the time reaching the object that improves insulation pipe structural strength, can not cause difficulty to the transport of pipeline and assembling.
Further, described thermal insulation layer adopts polyester ammonia bubble jet to record into, and polyurethane foam is a kind of composite with insulation and water-proof function, and its thermal conductivity is low, only 0.022~0.033W/ (m* Κ), and high insulating effect, fabricating cost is low.
Further, described outer tube comprises internal layer, steel band and skin, internal layer and skin all adopt high density polyethylene (HDPE) to make, internal layer has smooth inner surface, section is U-shaped steel band and is bonded in by high-performance binding resin in the mode being wound around the outer surface of internal layer, and skin is coated on the outer surface of internal layer and steel band.Taking U-shaped steel band as main support structure, improve the ring stiffness of tubing, in the time being subject to external impact force, reply original shape superior performance, high density polyethylene (HDPE) corrosion resistance is good, improves working life.
Compared with prior art, the utility model advantage is:
Insulation pipe described in the utility model is coated on thermal insulation layer outer surface with steel strip reinforced bellows, play a good protection, improved the structural strength of whole insulation pipe, impact resistance power is strong, base insulating layer is difficult for being damaged, and has improved the working life of insulation pipe; Insulation pipe described in the utility model is simple in structure, is easy to manufacture, and construction cost is low, and construction simple and fast, is applicable to large-scale application.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of insulation pipe radial cross-section;
Fig. 3 is the structural representation of the outer tube of details A in Fig. 1.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment who obtains under creative work prerequisite, all belong to the scope of the utility model protection.
The disclosed a kind of insulation pipe of the utility model embodiment, the structural strength of reinforcement pipeline, prevents that thermal insulation layer from being destroyed, and improves the working life of insulation pipe.
As shown in Figure 1 to Figure 2, a kind of insulation pipe, comprises inner tube 1, thermal insulation layer 2 and outer tube 3, inner tube 1 is wrapped up by thermal insulation layer 2, and thermal insulation layer 2 adopts polyester ammonia foam, under the effect of the multiple auxiliary agents such as stabilizer, catalyzer, fire retardant, mix by special device, form through high pressure sprinkling irrigation foam-in-place.Outside at thermal insulation layer is also enclosed with outer tube 3, and outer tube 3 adopts steel strip reinforced bellows.
Outer tube 3 comprises internal layer 4, steel band 5 and outer 6, internal layer 4 and outer 6 all adopts high density polyethylene (HDPE) to make, internal layer 4 has smooth inner surface, section is U-shaped steel band 5 and is bonded in by high-performance binding resin in the mode being wound around the outer surface of internal layer 4, and outer 6 are coated on the outer surface of internal layer 4 and steel band 5.
Insulation pipe described in the utility model is protected inner thermal insulation layer with the steel strip reinforced bellows with high ring rigidity; improve the structural strength of insulation pipe; while being subject to external impact force, reply original shape performance good, make the insulation pipe can long-acting stable normal work.
Below be only preferred implementation of the present utility model, it should be pointed out that above-mentioned preferred implementation should not be considered as restriction of the present utility model, protection domain of the present utility model should be as the criterion with claim limited range.For those skilled in the art, not departing from spirit and scope of the present utility model, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
