Description
Technical field
The utility model belongs to technical field of composite materials, and in particular to a kind of continuous fiber reinforced thermoplastic multiple tube.
Background technology
Oil and gas exploitation is well-known to the importance of country.Oil and gas exploitation industry is most in the past
Various steel pipes are used, most distinct issues are corrosion.With the development and the progress of technology of industry, passed in the urgent need to breaking through
The limitation in road under the overall leadership, seeks technology and the more preferable novel pipeline of economic performance.In recent years oil and gas industry is adopted more and more
Use nonmetal pipeline.In China, because oil-gas resource is many at desert, marsh, ocean and seabeach（From shallow sea to depth
Sea）In, corrosion-resistant anti-high pressure is again flexible flexible, and the reinforced thermoplastics pipe of very long continuous coil pipe can be made（RTP）Phase
Than the advantage that uniqueness is just provided with metallic conduit.
RTP compound pipeline complex pipeline production technologies are advanced, cost is low, function admirable, operating expenses is few and technology is easily supporting, is this
Deeply by the most attention of countries in the world, the country such as America and Europe, moral, method, English, day, Russia begins to research RTP early in the 70's and answered
The production technology of pipe is closed, the industrialized production stage is come at present.Current China has been in step for RTP PRODUCTION TRAITS
Section, Related product production technology needs upgrading badly.
A kind of glass fibers are disclosed in a kind of fiber glass thermoplastics pipe of Chinese patent 201220074379.7
Reinforced thermoplastics pipe is tieed up, is divided into internal layer, enhancement layer and protective layer, the protective layer material is fibre glass roving or glass
Cordage or the rope class treated through fiberglass surfacing, turn into enhancing band by plastic coating method and carry out being wound in pipe, due to heat
The viscosity of plastic resin is big, and rove and glass fiber rope and the rope class of glass processing are difficult fully to infiltrate therewith, so as to cause to do
Yarn is more, is extremely difficult to the theoretical strength of design, to reach that theoretical strength must add layer, necessarily causes the rigidity increase of RTP,
It is unfavorable for it into coiling song and transport, it is most important that the increase of its cost can be caused, is unfavorable for its popularization.
A kind of basalt fibre reinforced thermoplastics pipe of Chinese patent 201220580156.8, including internal lining pipe, winding
Fiber-reinforced layer and the outer jointing jacket being enclosed on outside fiber-reinforced layer outside internal lining pipe, although basalt fibre enhancing thermoplasticity is answered
Condensation material has been developed, and is all the product in the experimental stage mostly, and basalt fibre is scattered difficult, with thermoplastic resin knot
Poor with joint efforts, corresponding compatilizer, grafting agent exploitation is not in place, price and aspect of performance at all with fiberglass reinforced thermoplastic composite material
Material ratio, its application can only make related notion product, it is impossible to reach that volume production is even civilian.
Disclosed in a kind of continuous lod pipe of Chinese patent 201220738914.4, including body, and outside body
Portion is provided with external protection, if increasing between body and external protection provided with the wrapped dried layer continuous fiber on tube wall of spiral
Heat-flash is moulded
Property composite material prepreg layer.What this pipe country was used at present is all conventional method, in first extruded thermoplastic
Pipe, then winds enhancement layer on inner pipe, finally extrudes outer surface protective layer, the forming method of this method pipe belong to three into
Type method, manufacturing process is more, it is desirable to which machining accuracy is high.And at present, ripe European production line takes around the people of 2000-3000 ten thousand
Coin, domestic production line is also in development, it is contemplated that be also required to more than 10,000,000 RMB, this high cost investment, inefficient
Production hinders the application of RTP.
