Description

A kind of reinforced thermoplastics multiple tube and preparation method thereof
Technical field
The present invention relates to reinforced thermoplastics multiple tube fields, specifically, the present invention relates to a kind of enhancing thermoplasticity Plastic composite pipe and preparation method thereof.
Background technique
With the sustainable development of urban economy and the Rapid Expansion of city gas cause, the construction of cities and towns natural gas and application Scale constantly expands, and the safe handling of natural gas increasingly attracts people's attention.However, with cities and towns Natural Gas Demand pressure Gradually rise, Natural Gas High-pressure Pipeline laid in city it is more and more common, as every year because of safety accident caused by natural gas, and It causes casualties and property loss accident occurs again and again, cause the influence of very severe to society and gas enterprise, in addition to Reinforce also correctly selecting good pipe gas erection of equipment implementation specification outside natural gas line daily operation management Gas works material selects reasonable mounting means, to guarantee the life of numerous residents and the safety of property.Country cities and towns at present Natural gas line generallys use polyethylene (PE) pipeline and steel pipe, and PE pipe bearing capacity is lower, is easily scratched destruction and steel Pipe is difficult the reasons such as anti-corrosion, installation inconvenience and both tubing is caused to inhibit city natural gas pipeline in varying degrees, especially It is construction and the operation and management level of cities and towns Natural Gas High-pressure Pipeline, and then limits flourishing for cities and towns natural gas cause.
Compound pipeline complex pipeline is enhancing with steel wire, wirerope, glass, nylon etc. generally using high-density polyethylene plastics as matrix Body, reinforcement are embedded in interior outer plastic layer by being bonded or welded.Compound pipeline complex pipeline has significant mutually benefit effect, makes pipeline Performance be substantially better than the pipeline of single variety.The production of compound pipeline complex pipeline and producer are set by selecting different reinforcing materials Meter and manufacture are suitable for the pipeline of varying environment.The performance of compound pipeline complex pipeline is very excellent, in submarine oil-transportation, gas transmission, coal, chemical industry Equal fields have broad application prospects.West Europe, the U.S., Germany, Britain, Japan, Russia
The states such as Ross just put into the production skill of a large amount of human and material resources and financial resources research compound pipeline complex pipeline since the seventies Art.Currently, having been realized in industrialized production, manufacture, installation and control about compound pipeline complex pipeline.The research of China's compound pipeline complex pipeline And application, it starts late, but develop comparatively fast, main compound pipeline complex pipeline to be applied in China market, mostly uses metal as increasing at present Strong material, based on steel skeleton reinforcing material, he further include: plastic-aluminum, steel modeling and lining plastic composited pipe.
It is very unique and significant that RTP tube (reinforced thermoplastics pipe) has the advantages that: bearing capacity is very high, very resistance to Corrosion, while also keeping supplying with flexibility as HDPE tubing, the reel that can continuously grow several kms.At present in petroleum, day Right gas exploitation conveying, the fields such as various high-pressure fluid conveyings have promoted and applied, and development prospect is very wide.
The application improves existing RTP tube molding structure, prevents by providing completely new polyolefine material as multiple tube tubing Rotten ability, connection type.
Summary of the invention
It is an object of the present invention to provide a kind of reinforced thermoplastics multiple tubes.
Another object of the present invention is the provision of the preparation method of above-mentioned reinforced thermoplastics multiple tube.
Further object of the present invention is to provide a kind of novel polyolefin multiple tube raw material.
To solve plastic tube and steel pipe respective drawback in use, various structure types are all being studied in the whole world Novel tube.For many years, the new issue in industry there are many reinforced thermoplastics pipe puts forward, but can be abundant in market It is application and few, because really to accomplish that advantage and disadvantage complementation needs to solve many technical problems, reinforced thermoplastics Pipe is a very promising project.Such as oil and gas exploitation conveying, chemical industry, ore pulp and silt convey, are special severe The pipe-line system of environment is required to reinforced thermoplastics (RTP) composite pipe.Since current PE pipe-line system is also only applied Can high pressure natural-gas transfer pipeline below, pressure, on natural gas high pressure conveyance conduit in the pipe network end below 1MPa It is utilized, research and successful case at home and abroad is fewer and fewer.Comprehensively consider cost, usability, practicability, intensity It is taken as a kind of relatively broad pipe applications always in burning line with many factors, steel pipes such as reliabilities.But steel pipe by Broad development is also limited to a certain extent in its own feature, and wherein Anticorrosion is project the most serious.Due to steel pipe Density it is big, single steel pipe cannot be too long, therefore the workload that connects is very big when installing, and cost is very high, and steel pipe table Face needs to carry out preservative treatment, weight and needs very much mechanical handing, weld bond and erosion resistant coating that instrument is needed to detect Deng Eng again, therefore can increase Add more economic costs, and environment is had some impact on.Currently, polyethylene and aramid fiber successfully replace steel pipe in multiple necks Domain is applied, but bearing capacity too lower limit its further develop.Carbon fiber, aramid fiber and superhigh molecular weight polyethylene Expensive, the processing cost height of alkene fiber；The anti-conjunction pipe of fiber glass duct and the manufacturing process of lining plastic composited pipe are more Plastic layer and reinforcing material are bonded together by hot melt adhesive layer, in the fabrication process due to this multiple tube, metal-plastic Between compound interface, needs to realize that surface-to-surface is bonded, be difficult to control in technique, be locally commonly present gap, often occur in operational process The case where interfacial detachment, seriously affects the service performance of pipeline.
Metallic framework is later as a kind of appearance of Novel composite pipe road, but it overcomes the inherent shortcoming of above-mentioned pipeline.Gold Belong to skeleton reinforced plastic pipe, using HDPE as substrate, be respectively adopted different form formed be uniformly distributed, with gap Skeleton structure.It is compound to can be effectively solved aluminum plastic composite pipe, five layers of steel-plastics composite pipe and lining plastic for the presence in these gaps Due to steel skeleton and plastics percent thermal shrinkage differ greatly interfacial detachment phenomenon occurs for pipe under certain temperature and pressure, meanwhile, again Improve the Corrosion Protection of tubing.Meanwhile the unique texture of metallic framework, make it have excellent comprehensive performance: creep resistant, Corrosion-resistant, ant-scaling, it is wear-resistant, anti-aging, from tracer, flow resistance is small, and heat resistance is good, health it is nontoxic, do not cause secondary Pollution.Current: metal framework reinforced plastic composite pipe mainly has: steel wire spot welding networking reinforced plastic pipe-SPE pipe, hole pattern Steel strip-plastic multiple tube-PSSCP pipe, steel wire winding reinforced plastic pipe-PSP pipe and newly-invented rope belt twine Around reinforced plastic pipe-s-RTP.It is the material that can be applied to Natural Gas High-pressure Pipeline and need to explore.
