Abstract
The utility model discloses a glass fiber reinforced plastic oil pipe wound at a small angle, and relates to an oil pipe for an oil field. The glass fiber reinforced plastic oil pipe wound at the small angle is composed of glass fiber reinforced plastic pipes. The glass fiber reinforced plastic oil pipe is composed of an inner layer glass fiber reinforced plastic pipe, heat insulating foam and an outer layer glass fiber reinforced plastic pipe in an attached mode from inside to outside in sequence, wherein glass fibers are spirally wound to be pipe-shaped so as to form the inner layer glass fiber reinforced plastic pipe and the outer layer glass fiber reinforced plastic pipe, and circular-ring-shaped stainless steel tube connectors are arranged at two ends of the glass fiber reinforced plastic oil pipe. According to the glass fiber reinforced plastic oil pipe wound at the small angle, due to the fact that the axial stress of the glass fiber reinforced plastic oil pipe is increased, the glass fiber reinforced plastic oil pipe is durable in use, the number of layers of hoop winding is reduced, raw materials are saved, safety is improved, environmental pollution is reduced, the service life is prolonged, and the glass fiber reinforced plastic oil pipe wound at the small angle is reasonable in design, low in cost, light in weight, easy to install, and applicable to wide popularization and use.
Description
Technical field
The utility model relates to a kind of oil field oil pipe, relates in particular to the glass fiber reinforced plastic oil pipe that a kind of low-angle twines.
Background technology
In the process of recovering the oil in the oil field, glass fiber reinforced plastic is good with its antiseptic property, long service life and being widely applied to during flow string makes.The oil pipe environment for use is underground about a km, oil pipe will bear the circumferential pressure and the axial stress of bearing from aspects such as deadweight, sucker rod draft and hydraulic pressure of high pressure, the winding number of plies that increases high-pressure glass steel oil pipe can increase axial compression, but owing to increase the winding number of plies high-pressure glass fibre reinforced plastic pipe cost is increased, and circumference stress causes unnecessary waste again, make it popularize use and be restricted that transportation and installation are also inconvenient.Application number is: 200320100124.4 patent makes it durable in use by the glass fiber spiral being twined to increase the axial stress of glass oil pipe, saves material, addresses the above problem.But this patent is not paid attention to the insulation problem of oil pipeline, because oil pipeline mostly is glass reinforced plastic pipe greatly, oil in the glass reinforced plastic pipe can cool off very soon, oil cooling is attached in the tube wall after but, effective oil transportation caliber is diminished, and flow diminishes, and oil transportation speed has slowed down, must be spaced a distance and just build heating station and heat, the waste resource; And because inside and outside environmental corrosion steel pipe, the easy corrosion fracture in the junction of steel pipe has increased maintenance cost, and serious also can cause environment pollution.
Summary of the invention
The utility model is intended at the deficiency that exists in the background technology, and the glass fiber reinforced plastic oil pipe that a kind of low-angle that provides twines.
The glass fiber reinforced plastic oil pipe that low-angle of the present utility model twines, be to be constituted by glass reinforced plastic pipe, oil pipe is fitted by inner layer glass steel pipe, heat barrier foam and glass outer steel pipe successively from the inside to the outside and is formed, inner layer glass steel pipe and glass outer steel pipe all are to be wound in tubulose by the glass fiber spiral to form, and the two ends of oil pipe are provided with circular stainless steel joint for pipeline.
As further improvement of the utility model, heat barrier foam is a kind of in polyethylene, polypropylene foam, polyvinyl chloride foam, polyurethane foam, the phenol formaldehyde foam.
As further improvement of the utility model, all be provided with screw thread on the inside and outside circle side face of stainless steel joint for pipeline.
As further improvement of the utility model, the glass fiber hand of spiral and inner layer glass steel pipe and glass outer steel shaft to axial angle a be 5 °～10 °.
The glass fiber reinforced plastic oil pipe that the utility model low-angle twines, be wound up as tubulose by the glass fiber spiral and make glass reinforced plastic pipe, the axial angle of its hand of spiral and glass reinforced plastic pipe is at 5 °～10 °, increased the axial stress of glass fiber reinforced plastic oil pipe, make it more durable in use, reduce hoop simultaneously and twine the number of plies, save raw material; Inside and outside layer glass steel pipe therebetween is established heat barrier foam, heat insulation and preservation effect is good, and the distance between the heating station can zoom out, and reduces cost, and oil is difficult for cooling in the pipe, and inside pipe wall is non-cohesive to be condensed, and flow is big, and oil transportation is fast; The oil pipe two ends are provided with stainless steel joint for pipeline, adopt thread connecting mode thoroughly to solve the etching problem of pipeline and pipeline junction, reduce environment pollution when safety improves, and lengthen application life; The utility model is reasonable in design, cost is low, in light weight, easy installation, be fit to promote the use of.
Description of drawings
Fig. 1 is the structural representation of the glass fiber reinforced plastic oil pipe of low-angle winding of the present utility model.
The specific embodiment
Glass fiber reinforced plastic oil pipe below in conjunction with 1 pair of the utility model low-angle of accompanying drawing twines is described further.
The glass fiber reinforced plastic oil pipe that low-angle of the present utility model twines, be to be constituted by glass reinforced plastic pipe, oil pipe is fitted by inner layer glass steel pipe 1, heat barrier foam 2 and glass outer steel pipe 3 successively from the inside to the outside and is formed, inner layer glass steel pipe 1 and glass outer steel pipe 3 all are to be wound in tubulose by glass fiber 4 spirals to form, and the two ends of oil pipe are provided with circular stainless steel joint for pipeline 5.Heat barrier foam 2 adopts polyethylene, polypropylene foam, polyvinyl chloride foam, polyurethane foam, phenol formaldehyde foam or derivatives thereof, and heat insulation and preservation effect is good.All be provided with screw thread on the inside and outside circle side face of stainless steel joint for pipeline 5, reduce the convenient installation of burn into.The axial angle a of glass fiber 4 hands of spiral and inner layer glass steel pipe 1 and glass outer steel pipe 3 is at 5 °～10 °.
