Description

Continuous fiber reinforced thermoplastic composite high pressure pipeline
Technical field
The present invention relates to a kind of continuous fiber reinforced thermoplastic composite high pressure pipeline, be particularly useful for needing the thick fluid of hyperbaric heating transportation, belong to fluid-transporting tubing and technical field of polymer composite materials.
Background technique
According to the applicant understood, along with the continuous expansion construction in city and the continuous exploitation of oil and natural gas, also increasing to the demand of delivering pipe.Poor and the difficult carrying of traditional steel pipe corrosion resistance, cannot adapt to current needs; Oil carrier particularly, because oil stickiness is higher, when transportation need to every several kilometers build heating tank to pipeline heating, promote oil temperature, could improve oil flow, guarantee to transport smoothly oil, yet this can cause cost of transportation high undoubtedly.
Simultaneously, the main petroleum and natural gas of China is distributed in desert, marsh or mountain area more, physical environment is comparatively severe, while laying steel pipe, is subject to the impact of physical environment very serious, extremely easily occurs damaging phenomenon again because the reasons such as surface subsidence, landslide make conveyance conduit.
Through retrieval, find, there is at present multiple multiple tube, for example, the Chinese invention patent application of application number 2004800081319 publication number CN1764800A discloses a kind of fiber reinforced pipe, comprises the interior tubular liner that sets gradually from the inside to the outside, two-layer or three layers of reinforcing fiber layer, outer tubular sheath.Due to interior tubular liner and outer tubular sheath, by thermoplastic or elastomer, make, this reinforced pipe has flexibility, can realize coiling; Owing to being provided with reinforcing fiber layer, this reinforced pipe has shock resistance.Yet on the one hand, this reinforced pipe cannot be realized heating to the fluid in pipeline, is difficult to realize constant temperature transportation; On the other hand, this reinforced pipe adopts fiber to be directly wound around formation reinforcing fiber layer, complex production process, and high to equipment requirement, speed of production is slow, is unfavorable for enhancing productivity.
For another example, the Chinese invention patent application of application number 2008102295011 publication number CN101418886A discloses a kind of continuous fiber reinforced thermoplastic compound tube, comprise inside liner, outer surface layer and one deck enhancement layer at least, all take thermoplastic resin as matrix for these three layers, take continuous fiber as reinforcing material.This multiple tube can be improved the performances such as shock resistance, ageing-resistant, temperature tolerance, weatherability.Yet this multiple tube also cannot be realized heating to the fluid in pipeline, be difficult to realize constant temperature transportation.
Through further retrieval discovery, the disclosed self-heating high pressure resistant oil transmission pipeline of application number 2009202541904 notice of authorization CN201526737U Chinese utility model patent, the disclosed diesel engine SCR urea pipeline with heating function of application number 2011203198675 notice of authorization CN202220644U Chinese utility model patent, be equipped with carbon fiber heating layer, realization is heated, heating function.Yet claimant finds through practical studies, although these two kinds of pipelines can be realized heating by convection cells, the efficiency of heating surface is lower, and shock resistance a little less than.For the research of fiber reinforcement pipeline, find at present: when pipe interior is subject to compression swelling, enhancement layer fiber is tightened provides anti-pressure ability, but because Single Fiber contraction ratio is definite value, often outermost fibers has been tightened stressed and inner fiber still in relaxed state, make the whole unbalance stress of tubing enhancement layer, cannot reach high pressure usage requirement.
In addition, according to the knowledge of the applicant, the caliber maximum of similar multiple tube can only reach 150mm in the world at present, if be greater than this caliber, cannot guarantee pipeline strength.
