Abstract
The present invention relates to a kind of composite strengthening Winding pressure pipe.It, which has, is difficult the features such as burn into intensity is high, carrying is big, lightweight, it is ensured that oil, the long-term safety conveying of natural gas.The composite strengthening Winding pressure pipe is made up of inner liner, inner structural layer, enhancing winding layer, protective layer.Inner liner is that thermoplastic material or resin material solidification are formed; inner structural layer is entwined by polymer matrix composites; enhancing winding layer is entwined by bamboo chip with enhancing winding band cross-helicity; including at least more than 2 layers winding layers; and winding angle of two layers of change is often wound, protective layer is to be formed by resin-based materials and the coating of other water-proof and anti-corrosive materials.The present invention is corrosion-resistant, high pressure resistant, lightweight, is equally applicable to the pipeline fields such as sewage, electric power, heating power, communication.
Description
Technical field
The present invention relates to multiple tube field, more particularly to a kind of composite strengthening Winding pressure pipe.
Background technology
Pipeline is increasingly subject to extensive concern as oil, the main mode of movement of natural gas, its reliability and security,
Current oil, natural gas mainly carry out long distance delivery using steel pipe, and it is to influence the main factor of pipeline failure to corrode, existing
Although some nonmetal pipelines having avoid corrosive pipeline problem, but its bearing capacity is relatively low, are not suitable for oil, natural gas
Long distance delivery.Once pipeline is leaked, the wasting of resources, pollution environment are not only resulted in, blast, fire etc. is also resulted in
Accident occurs, and non-people's life and property bring danger, while the dimension repairing of pipeline is time-consuming, expensive.Thus, how effectively to drop
Low corrosive pipeline, is a current oil and gas industry major issue urgently to be resolved hurrily while ensureing its bearing capacity.Therefore, design
A kind of composite strengthening Winding pressure pipe, it is to avoid corrosive pipeline problem, while having higher bearing capacity again, it is ensured that stone
Oil, the safe transport of natural gas, simultaneously can be used for the industries such as sewage, electric power, combustion gas, communication.
The content of the invention
The purpose of the present invention is：In order to overcome pipeline in existing petroleum gas field easily to occur the failures such as burn into rupture
Problem, spy provides a kind of composite strengthening Winding pressure pipe, it is to avoid the etching problem of conventional steel pipe, while having higher pressure-bearing
Ability, it is ensured that oil, the long-term normal conveying of natural gas.
To achieve these goals, the present invention uses following technical scheme：A kind of composite strengthening Winding pressure pipe, is by interior
Lining, inner structural layer, enhancing winding layer, protective layer composition, it is characterised in that：Inner liner is thermoplastic material or resinous wood
Material solidification is formed, and inner structural layer is entwined by polymer matrix composites, and enhancing winding layer is intersected by bamboo chip with enhancing winding band
Spiral winding is formed, and protective layer is to be formed by resin-based materials and the coating of other water-proof and anti-corrosive materials.
As further technical scheme, resin base is used between inner liner, inner structural layer, enhancing winding layer, protective layer
Binding material is bonded.
As further technical scheme, the section of bamboo chip and enhancing winding band in enhancing winding layer is rectangle, and
Intersect spiral winding, and enhancing winding band other fibrous materials can be made up of steel band or glass fibre, organic fiber, strap etc.
Fibrous wrapping tape.
As further technical scheme, enhancing winding layer comprises at least more than 2 layers winding layers, often winds one layer, uses
Outside resin-based materials coating winding layer and bamboo chip and enhancing the winding gap between, often winds two layers, changes a winding angle
Degree.
The beneficial effects of the invention are as follows：(1) inner liner of composite strengthening Winding pressure pipe is in thermoplastic material, pipe
Fluid does not come in contact with metal, will not occur corrosion phenomenon；(2) enhancement layer is wound with composite winding using bamboo chip with enhancing
Into, the intensity and bearing capacity of multiple tube are improved, bamboo chip is renewable resource, and easily decomposition, environmental protection；(3) strengthen
Winding band be steel band or other fibrous wrapping tapes, with intensity it is high, it is lightweight the features such as, the weight for the whole multiple tube for being is very big
Mitigate；(4) composite strengthening Winding pressure pipe mainly uses winding process, and production efficiency is high, can largely be produced.
