Abstract

The utility model relates to a heat preservation pipeline, including a pipe body, the wall of body is to interior pipe wall skin, heat preservation foaming layer, pipe wall intermediate level, fibre preimpregnation lacing and the pipe wall inlayer of being in proper order outside from, the heat preservation foaming layer is polyurethane foam layer or polystyrene foaming layer, the pipe wall is outer, pipe wall intermediate level and pipe wall inlayer are in PP material layer and the PE material layer any one. The utility model provides an among the prior art the pure conveyer pipe that moulds say the relatively poor problem of ring rigidity, bellied strengthening rib can make this pipeline avoid the easy vertical problem that contracts of returning of body in the work progress from the body simultaneously, increases the ground nature of grabbing of pipeline, more is favorable to the construction operation, it design scientific and reasonable, the ring rigidity is high, the heat insulating ability is good, material cost is cheap, manufactures the convenience, corrosion resistance is strong, transported substance expects safe and reliable.

Description

A kind of insulation conveyance conduit

Technical field

This utility model relates to conveyance conduit, specifically one insulation conveyance conduit.

Background technology

At present industrial undertaking produces the conveyance conduit of the fluids such as conveying Oil, Water, Gas, commonly used steel pipe and be wrapped in the structure of the heat-insulation layer outside steel pipe, protective layer.As CN103090156B discloses a kind of energy-conservation conveyance conduit of vacuum heat-insulating hot fluid, including interior fluid hose and outer steel pipe, described interior fluid hose is set in outer steel pipe, the two ends of outer steel pipe are sealed by head plate and make to be formed between described two pipes vacuum heat-insulating layer, and this vacuum heat-insulating layer connects with airtight valve.This invention uses triple heat insulation structures, to reduce the thermal energy radiation loss during steam, delivery and condensation knot, solves existing conveyance conduit list (double) journey heat loss amount relatively large, and heat loss rate is higher, the problem that heat utilization efficiency is relatively low.But, the conveyance conduit of this metal structure generally exists processing, and the prices of raw materials are higher, technique very complicated, production cost high and for carrying some liquid, it easily produce the shortcomings such as corrosion.For overcoming these defects, the technical staff in industry constantly studies the pipeline of plastic material, to alternative metals pipeline, reaches corrosion-resistant, processes simple, the purpose of low cost.But, the ring stiffness of existing plastic conveying and plastic pipeline is poor, runs into the higher liquid of some temperature or gas, body longitudinally retraction and the problem of dilatancy easily occurs, and during for long distance delivery, its heat-insulating property also relative mistake.

Utility model content

The purpose of this utility model is just to provide a kind of insulation conveyance conduit, to solve existing conveyance conduit or as metal material, has that cost of material is high, prepares very complicated, problem that corrosion resistance is poor；For plastic material, there is the problem that ring stiffness is poor, heat-insulating property is poor.

The purpose of this utility model is achieved in that a kind of insulation conveyance conduit, and including body, the wall of described body is followed successively by tube wall outer layer, thermal insulation foaming layer, tube wall intermediate layer, fiber prepreg belt and tube wall internal layer from outside to inside；Described thermal insulation foaming layer refers to polyurethane foaming layer or foamed polystyrene layer；Described tube wall outer layer, tube wall intermediate layer and tube wall internal layer are any one in PP material layer and PE material layer.

The thickness of described tube wall outer layer accounts for the 2-20% of the wall thickness of body, the thickness of described thermal insulation foaming layer accounts for the 10-80% of wall thickness of body, the thickness in tube wall intermediate layer accounts for the 3-30% of wall thickness of body, the thickness of fiber prepreg belt accounts for the 2-15% of wall thickness of body, the thickness of tube wall internal layer accounts for the 5-30% of wall thickness of body.

On the tube wall outer layer of described body, spiral winding has reinforcement；The hollow cylinder that described reinforcement is PE material or prepared by PP material.

This utility model is followed successively by tube wall outer layer, thermal insulation foaming layer, tube wall intermediate layer, fiber prepreg belt and the five-layer structure of tube wall internal layer from outside to inside by being designed as by the wall of described body, solve in prior art that pure plastic conveying and plastic pipe ring rigidity is poor, run into the higher liquid of some temperature or gas, body longitudinally retraction and the problem of dilatancy, and the problem of heat-insulating property also relative mistake easily occur.Meanwhile, this utility model is outside equipped with the reinforcement of projection at body, can further enhance the ring rigidity of pipeline, and make this pipeline can increase the adherence properties of pipeline in work progress, is more beneficial for the concrete operation of construction.This utility model design science is reasonable, and ring rigidity is high, good heat preservation performance, low raw-material cost, and it is convenient to manufacture, and adherence properties is preferable, the labor intensity of workmen when reducing installation, and corrosion resistance is strong, improves the reliability of conveying material.

Accompanying drawing explanation

Fig. 1 is schematic cross-section of the present utility model.

Fig. 2 is the schematic diagram that this utility model is wound around reinforcement.

Detailed description of the invention

As shown in Figure 1, the insulation conveyance conduit that this utility model provides, the longitdinal cross-section diagram of this body 1 is annular, the wall of its body 1 includes the tube wall outer layer 11 prepared by PE material the most respectively, the thermal insulation foaming layer 12 prepared by polyurethane foam material, the tube wall intermediate layer 13 prepared by PE material, the fiber prepreg belt 14 prepared by glass fibre and the tube wall internal layer 15 prepared by PE material.Preferably, in the preparation, the wall of body 1 can be prepared as the thickness of tube wall outer layer 11 accounts for the 15% of wall gross thickness of body, the thickness of thermal insulation foaming layer 12 accounts for the 40% of wall gross thickness of body, the thickness in tube wall intermediate layer 13 accounts for the 15% of wall gross thickness of body, the thickness of fiber prepreg belt 14 accounts for the 10% of wall gross thickness of body, the thickness of tube wall internal layer 15 account for body wall gross thickness 20%.Under being preferably provided with, ring stiffness and the heat-insulating property of this conveyance conduit are more preferable.

As shown in Figure 2, the reinforcement 2 of spiral winding on tube wall outer layer 11, the hollow cylinder that this reinforcement 2 is PE material or prepared by PP material, and tube wall outer layer 11 and reinforcement 2 melt and are integrated, such ring rigidity being designed to increase body further, the adherence properties of body can also be increased, the construction that more convenient pipeline connects.

Additionally, the tube wall outer layer 11 of insulation conveyance conduit of the present utility model, tube wall intermediate layer 13 and tube wall internal layer 15 can also be prepared from by PP material；Thermal insulation foaming layer 12 can also be prepared from by polystyrol foam material.

The foregoing is only preferred embodiment of the present utility model, be not limited to this utility model, for a person skilled in the art, this utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
