Description
Technical field
The present invention relates to pipeline processing manufacturing technology fields, apply the control of fiberglass reinforced flexibility more particularly to a kind of ocean
Make method.
Background technique
Glass fibre continuously enhances the compound pipeline complex pipeline that thermoplastic composite tube is a kind of novel high-performance glass fiber reinforcement.?
In the inner tube of thermoplastic extrusion molding, then the enhancement layer being wound with the glass fibres prepreg tape such as PP/PE squeezes again
Thermoplastic is external protection out.Between ectonexine and fiberglass layer, be all same molecular structure, melting key between intermediate fiberglass layer
It closes, three layers of complete weldings one form a solid wall pipe, with light-weight, intensity is high, at low cost, corrosion-resistant, environmentally protective etc.
Advantage has been applied to land oil, gas and water gathering line, high pressure water injection pipeline, hot wash pipeline and offshore oil production standpipe etc..But
It is that glass fibre continuously enhances in thermoplastic composite tube manufacturing process that there are glass fibre prepreg tape welding fracture, bonding are uneven
Phenomena such as even, in turn result in each delamination of multiple tube, it is resistance to force down with tubing specification can not unify and other issues.
Summary of the invention
For this purpose, bonding uniform fiberglass reinforced flexible pipe an object of the present invention is to provide a kind of not easy to break
Manufacturing method.
The present invention provides a kind of ocean apply fiberglass reinforced flexibility pipe manufacturing method, fiberglass reinforced flexible pipe obtained by
Interior arrive includes inner tube, enhancement layer and external protection three-decker outside, comprising:
Step S1 quickly heats the surface of inner tube, its surface is made to generate molten condition；
Step S2, using two or two or more glass fibre prepreg tapes outside the inner tube of the molten condition lateral edge
Different angles carries out delamination helix winding, forms enhancement layer；
Step S3 coats external protection material on the outside of enhancement layer, completes the manufacture of fiberglass reinforced flexible pipe.
Further, in the step S1, the 1/2 of the wall thickness of inner tube is no more than to the thickness of inner tube melting.
Further, in the step S2, the winding direction of adjacent layer glass fiber prepreg tape is opposite；Or it is adjacent
The winding in the same direction of four-layer glass fiber prepreg tape two, another two reverse-windings.
Further, in winding, there are gaps between the edge of same glass fibre prepreg tape.
Further, after the glass fibre prepreg tape of every winding setting number of plies, it is heated by heating device, is glued
Knot solidification；Until reaching the number of plies of design, enhancement layer is formed.
Further, the number of plies set is 2~5 layer.
Further, the material of the inner tube and external protection be polyethylene, polypropylene, heat-proof polythene or nylon,
The medium or external environment conveyed as needed is selected.
Fiberglass reinforced flexibility pipe manufacturing method is applied in ocean of the invention, has fully considered glass fibre prepreg tape intolerant to height
The disadvantages of warm, easily broken, using transient heating inner tube surface melting, make its quickly with the glass fibre prepreg tape phase of spiral wound
Adhesive solidification, can also be every the glass fibre prepreg tape of 2~5 layers of spiral winding, and repetition is heating and curing to surface, effectively
Ground avoids glass fibre prepreg tape welding fracture, bonds non-uniform problem, improves product quality.Meanwhile it is of the invention
Winding direction of the compound glass fiber prepreg tape on the outside of inner tube is staggered, can effectively improve the intensity of enhancement layer, be not easy
Fracture.
Additional aspect and advantage of the invention will be set forth in part in the description, and will partially become from the following description
Obviously, or practice through the invention is recognized.

Specific embodiment
The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning to end
Same or similar label indicates same or similar element or element with the same or similar functions.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to is used to explain the present invention, and is not considered as limiting the invention.
The embodiment of the invention provides a kind of oceans to apply fiberglass reinforced flexibility pipe manufacturing method, as shown in Fig. 2, obtained
Fiberglass reinforced flexible pipe includes 3 three-decker of inner tube 1, enhancement layer 2 and external protection from inside to outside；As shown in Figure 1, ocean is answered
Include: with the step of fiberglass reinforced flexibility pipe manufacturing method
Step S1 quickly heats the surface of inner tube, its surface is made to generate molten condition.Preferably, to internal layer
The thickness of pipe melting is no more than the 1/2 of the wall thickness of inner tube, and the shape and size to ensure inner tube are unaffected.
Step S2, using two or two or more glass fibre prepreg tapes outside the inner tube of the molten condition lateral edge
Different angles carries out delamination helix winding, forms enhancement layer.Wherein, as shown in figure 3, adjacent layer glass fiber prepreg tape
The winding direction of 2-1 is opposite；Or as shown in figure 4, two windings in the same direction in adjacent four-layer glass fiber prepreg tape 2-1, separately
Two reverse-windings.For the winding angle of single glass fibre prepreg tape 2-1, multiple tube is that there is no balances for caking property pipeline
Angle problem, therefore winding angle does not limit, it can any angle winding；Each winding one is enclosed, between glass fibre prepreg tape 2-1 tape
Form small―gap suture 2-2；Every the glass fibre prepreg tape 2-1 of 2~5 layers of spiral winding, heating melting again, and pass through winding
Clamp force compresses bonding, until reaching the number of plies of design, forms enhancement layer.Wherein, there are gap can prevent winding machine monitoring
It is insufficient to wind stroke accuracy, same layer occurs and overlaps phenomenon, influence subsequent melt quality.
Step S3 coats external protection material on the outside of enhancement layer, completes the manufacture of fiberglass reinforced flexible pipe.The internal layer
The material of pipe and external protection is polyethylene, polypropylene, heat-proof polythene or nylon, the medium conveyed as needed or extraneous ring
Border is selected.
Fiberglass reinforced flexibility pipe manufacturing method is applied in ocean of the invention, has fully considered glass fibre prepreg tape intolerant to height
The disadvantages of warm, easily broken, using transient heating inner tube surface melting, make its quickly with the glass fibre prepreg tape phase of spiral wound
Adhesive solidification, can also be every the glass fibre prepreg tape of 2~5 layers of spiral winding, and repetition is heating and curing to surface, effectively
Ground avoids glass fibre prepreg tape welding fracture, bonds non-uniform problem, improves product quality.Meanwhile it is of the invention
Winding direction of the compound glass fiber prepreg tape on the outside of inner tube is staggered, can effectively improve the intensity of enhancement layer, be not easy
Fracture.
Although the embodiments of the present invention has been shown and described above, it is to be understood that above-described embodiment is example
Property, it is not considered as limiting the invention, those skilled in the art within the scope of the invention can be to above-mentioned
Embodiment is changed, modifies, replacement and variant.
