Abstract
The utility model relates to a liquid transmission pipeline, in particular to a polyurethane rigid foam PP-R heat preservation anticorrosion pipeline which comprises a pipeline outer layer, a pipeline inner layer and a middle layer. The pipeline outer layer wraps the pipeline inner layer, and the pipeline inner layer wraps the middle layer. The pipeline outer layer is an outer protective layer made of high-density polyethylene, the pipeline inner layer is made of PP-R tubular products, and the middle layer is made of polyurethane rigid foam. The polyurethane rigid foam PP-R heat preservation anticorrosion pipeline is good in heat preservation performance, capable of bearing pressure, remarkable in anticorrosion performance and easy and convenient to construct, the pipeline can be connected directly in a hot-melt mode, and the service life can reach fifty years.
Description
technical field:
The utility model relates to a kind of liquid conducting pipes, is specifically related to a kind of hard polyurethane foam PP-R insulation antiseptic pipeline.
background technique:
At present, liquid conducting pipes is often polyethylene pipe or steel pipe, be embedded in underground rear thermal insulation property poor, and the resistance to high temperature of polyvinyl piping materials is poor should not be used for heating network, in prior art, insulation antiseptic pipeline is made up of steel pipe medium transport pipe mostly, a kind of urethane foam insulation pipe as disclosed in utility model patent CN203404562U, comprise steel pipe, anticorrosive coat, urethane foam thermal insulation layer, low temperature resistant cracking resistance high-density polyethylene external protective pipe, reserved welding section, the excircle parcel anticorrosive coat of steel pipe, the excircle parcel urethane foam thermal insulation layer of anticorrosive coat, the excircle of urethane foam thermal insulation layer wraps up low temperature resistant cracking resistance high-density polyethylene external protective pipe, there is respectively reserved welding section at the two ends of steel pipe.The easy corrosion of steel pipe medium transport pipe that it is inner, antiseptic property is poor, and bad mechanical strength, and weld bond between pipeline welds operates more complicatedly, a little less than join strength, causes working life short, and construction and installation are time-consuming, effort, and cost is high.
summary of the invention:
In order to overcome the deficiencies in the prior art, the utility model provides a kind of hard polyurethane foam PP-R insulation antiseptic pipeline, can in reaching heat insulation effect, play anticorrosion, pressure-bearing effect, and connect quick, easy.
For solving the problems of the technologies described above; the utility model is taked following technological scheme: a kind of hard polyurethane foam PP-R insulation antiseptic pipeline; comprise pipeline outer-layer, pipeline lining, mesosphere; pipeline outer-layer parcel pipeline lining; pipeline lining parcel mesosphere; pipeline outer-layer is high density polyethylene (HDPE) external protection, and pipeline lining is PP-R tubing, and mesosphere is hard polyurethane foam.
Described pipeline outer-layer is high density polyethylene (HDPE) external protection, and this layer is protecting jacket, blocks air, moisture and plays the moulding effect in mesosphere; Described pipeline lining is PP-R tubing, claim again three type polypropylene tube, adopt atactic copolymerized polypropene through being extruded as tubing, injection moulding becomes pipe fitting, has the features such as lightweight, corrosion-resistant, non-scaling, long service life, there are good shock resistance and long-term creep behaviour, also have good welding performance, tubing, pipe fitting can adopt hot melt to be connected with electric smelting, easy for installation, the intensity of its connection part is greater than the intensity of tubing itself, and it is mainly conveying liquid substance; Described mesosphere is hard polyurethane foam, mainly plays insulation effect, therefore, has just reached and has been incubated and corrosion-resistant object.
The beneficial effects of the utility model: not only excellent thermal insulation performance, can pressure-bearing, and also antiseptic property is obvious, easy construction, and when connection, directly hot melt connects, and can reach 50 years working life.
brief description of the drawings:
?fig. 1 is structural representation of the present utility model.
In figure: 1, pipeline outer-layer, 2, pipeline lining, 3, mesosphere.
embodiment:
Below in conjunction with accompanying drawing, the technical solution of the utility model is further described.
As shown in Figure 1; this embodiment is by the following technical solutions: a kind of hard polyurethane foam PP-R insulation antiseptic pipeline; comprise pipeline outer-layer 1, pipeline lining 2, mesosphere 3; pipeline outer-layer 1 wraps up pipeline lining 2; pipeline lining 2 wraps up mesosphere 3; pipeline outer-layer 1 is high density polyethylene (HDPE) external protection, and pipeline lining 2 is PP-R tubing, and mesosphere 3 is hard polyurethane foam.Described pipeline outer-layer 1 is high density polyethylene (HDPE) external protection, and this layer is protecting jacket, blocks air, moisture and plays the moulding effect in mesosphere; Described pipeline lining 2 is PP-R tubing, and it is mainly conveying liquid substance; Described mesosphere 3 is hard polyurethane foam, mainly plays insulation effect.This hard polyurethane foam PP-R insulation antiseptic pipeline is compared with hard polyurethane foam insulation antiseptic steel pipe, not only excellent thermal insulation performance, can pressure-bearing, and antiseptic property is obvious, easy construction, when connection, directly hot melt connects, and can reach 50 years working life, cost is low, is easy to large-scale promotion application.
