Abstract
The utility model provides a pressure pipe whose cost is low and structure is simple and that meets all requirements of various materials to transport pipes. The utility model is composed of an inner pipe, a fibrous stratum, an incrassated layer, a pressure equalizing layer and an outer pipe that are arranged from the inside to the outside in turn. The utility model adopts biomimetic structure, thereby greatly improving the pressure resistance, meeting the requirements of oil gas transport and high pressure pipe pressure resistance and compared with other pipes, having unexampled excellent performance at the aspect of heat preservation, etc.
Description
(1) technical field
The utility model relates to the bionical pressure-resistant pipeline of a kind of plant xylem, specifically a kind of pressure-resistant pipeline that is used to transport highly pressurised liquid, gas.
(2) background technique
At present, the steel pipes that adopt in the conveying of petroleum gas owing to pipe quality is big, have brought inconvenience for the transportation construction more.On the other hand, the corrosion resistance of steel pipe is relatively poor, the cost height.Now existing PE, PVC, PP pipeline because pipeline self structure design problem resistance to pressure is low, simple in structure, have limited the scope of its use.As the patent No. is 200520085402.2 model utility, discloses a kind of pressure-resistant pipeline, by inner tube, external pipe and compound fiber reinforcement band between them.Though can bear certain high pressure, there is not relevant insulating structure, be unsuitable for the material that freezes easily at low temperatures in severe cold areas transport of water etc.
(3) summary of the invention
The utility model provides a kind of with low cost, simple in structure at the deficiencies in the prior art, is fit to most of liquid, gaseous substance under varying environment, especially comparatively under the rigorous environment, still can satisfy the pressure-resistant pipeline that pipeline transport requires.
A kind of pressure-resistant pipeline is arranged in order from the inside to the outside by interior pipe, layer of fibers, thickening layer, equalizing press layer and outer tube and constitutes.
Described layer of fibers constitutes for being twined by 3～5 layers of fibre compact, and every layer of fiber winding direction is identical, the winding direction difference of each layer fiber.
Described thickening layer is porose structure.
Described equalizing press layer is filled by hollow bead and is constituted, and hollow bead includes liquid or gas.
The objective of the invention is by plant xylem vessel is had good resistance to pressure, certain characteristics such as heat insulating ability are carried out bionics Study and its good characteristic are applied in the pressure-resistant pipeline, make the pressure-resistant pipeline of production possess performances such as similar withstand voltage, insulation.The good characteristic of flora conduit is realized by cell wall, conduit and three levels of xylem.Layer of fibers of the present utility model, thickening layer and equalizing press layer; carry out bionical research based on structure respectively to above-mentioned three levels; effectively use its structural feature, and added interior pipe and outer tube, in order to corrosion-damaged to body of transportation material and pipeline outside ring border in the protection pipeline.
The beneficial effects of the utility model are: owing to adopted above-mentioned biomimetic features, resistance to pressure is greatly improved, and has satisfied liquid, gaseous matters such as oil gas conveying, high pressure water in transit to the requirement of pipeline resistance to pressure and heat insulating ability.Compare with common steel tube, this bionical pressure-resistant pipeline anti-corrosion capacity is strong, long service life, and quality is lighter, and flexible rolling is convenient to construction.Compare with the common PE pipeline, when reaching identical compressive strength, economize in raw materials, reduce and produce the cost that uses, and wait aspect other, have the unrivaled good characteristic of other pipeline in insulation.
