Abstract

The utility model belongs to the technical field of plastic composite tubes, and discloses a coiled type reinforce plastic composite tube. The technical scheme for forming the composite tube is as follows: an inner tube layer is made of plastic materials; a wear-resisting fiber layer formed by terylene industrial fiber, aramid fiber and glass fiber is wound or braided on an outer wall of the inner tube layer; a modified high-molecular polymer anticorrosion protective layer is coated on an outer surface of the fiber layer; and the inner tube layer, the fiber layer and the protective layer are combined to form an integral structure. The coiled type reinforced plastic composite tube has the advantages of small bending radius, strong wear-resisting and corrosion-resistance performance, and high loading capacity.

Description

But coiling reinforced plastic pipe
Technical field
The utility model belongs to the compound plastic pipe technical field, but relates in particular to a kind of coiling reinforced plastic pipe that is used in the fields such as oil, chemical industry, ocean.
Background technique
In recent years, along with the fast development of China's economy, every profession and trade rolls up the demand of the energy, and especially the dependence to petroleum resources is stronger, and existing oil and gas industry production gathers for delivery of sewage, notes and strong corrosive media (as contains hydrogen sulfide, CL -, CO 3Rock gas etc.) pipeline generally adopt steel pipe or Glass Steel Tube, wherein the defective of steel pipe is that weight is large, perishable, working life short, the defective of Glass Steel Tube is that creep resistance is poor, maintenance difficulty large, can't recycle after scrapping, and is easy to cause environmental pollution.
For the problem of present existence, multiple corrosion-resistant plastic composite pipe has appearred in the conveyance conduit technical field, and wherein internal layer, middle level and outer interlayer all are provided with sticker layer, the composite pipe that mutually is bonded into one; The bending pipes radius was excessive after this kind formed the composite pipe shaping of integrative-structure, gave in the storage, transportation, laying, installation process of tubing and had caused inconvenience.
The model utility content
But the purpose of this utility model just provides a kind of coiling reinforced plastic pipe that the bending pipes radius is little, bearing capacity is high after the moulding that has.
To achieve these goals, the technical solution adopted in the utility model is:
But a kind of coiling reinforced plastic pipe is characterized in that: include the plastic inner pipe layer, twine or be woven with 2-6 layers abrasion resistant fibrous layer at this inner tube layer outer wall, this fibrolaminar outer surface is coated with corrosion protective covering; Described inner tube layer, layer of fibers and the protective layer structure that is combined into one.
But the additional technical feature that consists of above-mentioned a kind of coiling reinforced plastic pipe comprises:
---described abrasion resistant fibrous layer is made of thinner terylene industrial fiber, aramid fibre or the glass fibre of diameter and diameter thicker steel wire mixed weaving or winding;
---consist of in each described abrasion resistant fibrous layer Heterogeneous Permutation between the thicker steel wire of terylene industrial fiber, aramid fibre or the glass fibre that described diameter is thinner and described diameter;
---the angle that consists of fiber that the institute of described abrasion resistant fibrous layer twines or weave and steel wire and composite pipe tubing shaft axis is 54 ° 47 ' or 67.79 '.
But coiling reinforced plastic pipe provided by the utility model is compared with prior art, have the following advantages: one, adopt non-bonded structure owing to consist of inner tube layer, layer of fibers and the corrosion protective covering of this composite pipe, so that the composite pipe bending radius after the moulding is less, easy to use, transportation and store; Its two because fiber-reinforced layer and tubing shaft axis become 54 ° 47 ' or 67.79 ' angle, be bidirectional crossed winding structure, can make the hoop of composite pipe and axial strength and bearing capacity improve 2-3 times.
Description of drawings
But Fig. 1 is the radial cross section structural representation of the coiling reinforced plastic pipe of the utility model confession;
Fig. 2 is the structural representation of the abrasion resistant fibrous layer of above-mentioned composite pipe;
Fig. 3 is the tube wall axial cross section structural representation of above-mentioned reinforced plastic pipe.
Embodiment
Below in conjunction with accompanying drawing but a kind of structure to the coiling reinforced plastic pipe provided by the utility model is described in further detail.
As shown in Figure 1, but be the radial section structural representation of a kind of coiling reinforced plastic pipe provided by the utility model.The structure that consists of this reinforced plastic pipe comprises the inner tube layer 1 of being made by macromolecule polymer material, twine or be woven with the abrasion resistant fibrous layer 2 that is made of terylene industrial fiber, aramid fibre, glass fibre at this inner tube layer outer wall, the outer surface of this abrasion resistant fibrous layer 2 is coated with modified high-molecular polymer corrosion protective covering 3; Above-mentioned inner tube layer 1, abrasion resistant fibrous layer 2 and protective layer 3 structure that is combined into one.
But consist of in the structure of above-mentioned coiling reinforced plastic pipe, shown in Fig. 2,3
---abrasion resistant fibrous layer utilizes three layers to be made of the thinner terylene industrial fiber of diameter, aramid fibre or glass fibre 4 and diameter thicker steel wire 5 mixed weavings or winding layer, and the thicker steel wire 51 of each interlayer diameter and 52 are Heterogeneous Permutation; The composite pipe that the abrasion resistant fibrous layer 2 that this mixed weaving or winding consist of forms has the characteristics of withstand voltage and wear-resisting long service life; Wherein, according to the requirement of composite pipe diameter and intensity, the number of plies that consists of terylene industrial fiber, aramid fibre or glass fibre 4 and the steel wire 5 of abrasion resistant fibrous layer can be set to four layers or six layers of structure.
---consist of terylene industrial fiber, aramid fibre, glass fibre and steel wire 4 that the institute of wearing layer 2 twines or weave, 5 and the included angle A of tubing shaft axis B be 54 ° 47 ' or 67.79 ', changed winding angle and be 54.73 ' the tradition selection.By changing winding angle, layer thickness can reduce about 15%, under this braiding or winding angle, has improved on the one hand the hoop tensile strength of tubing, make on the other hand hoop intensity and the axial tensile strength state that tends to balance, can effectively improve the bearing capacity of tubing.Change winding angle and be the major measure that changes fixed length Fw Frp Pipe hoop and the ratio of axial tensile strength.It is more favourable to the fixed length winding process to increase winding angle.Suitably increase winding angle, reduce the thickness of pipeline, still can not reduce the axial strength safety coefficient, like this can the decrease engineering cost.
Because the bending radius of the composite pipe of this structure diminishes, therefore installing, can significantly reducing Contraction in Site band area when laying, reduce the difficulty that construction is laid.
