Abstract

The utility model provides a pressurized composite tube which comprises an inner tube and is characterized in that the inner tube is a PVC tube or a stainless steel tube; the exterior of the PVC inner tube or stainless steel inner tube is compounded with a steel tube or a glass bundle radially wound. The composite pressurized tube has higher bearing capacity, better corrosion resisting performance, smaller flow resistance, proper weight and low manufacturing cost, can be used in water conservancy and water-power engineering construction, is conductive to reducing construction cost, prolonging the service life of pipes and reducing the operation cost, and can be widely applied to pipage construction of chemical industry, metallurgy and other industries.

Description

A kind of have a pressure composite pipe

Technical field

The utility model relates to a kind of composite pipe, and especially a kind of have a pressure composite pipe, belongs to piping design and manufacturing technology field.

Background technique

Pressure conduit not only will carry impact force from various media, striking force, frictional force etc. in discharge pressure medium process, tolerate the corrosion of various media, but also must have less flow resistance, to carry various pressure mediums unblockedly.Though but existing single steel pipe has higher capacity,, and make its application area limited because of poor corrosion resistance, flow resistance are big.In addition, though single Stainless Steel Tube has possessed higher capacity, decay resistance and less flow resistance preferably are because of its cost height, Heavy Weight can not use on a large scale.Have again, though single pvc pipe has decay resistance and less flow resistance preferably, and also in light weight, be widely used as the aqueduct in the building, because bearing capacity is limited, can not be applied in important engineering such as water conservancy, the hydroelectric project.Therefore, be necessary to develop new multiple tube, to satisfy water conservancy, construction of hydropower plant needs.

Summary of the invention

The purpose of this utility model is to overcome the deficiency of prior art, and a kind of pressure composite pipe that has is provided.

The utility model is finished by following technical proposal: a kind of have a pressure composite pipe, comprises interior pipe, and pipe is pvc pipe or Stainless Steel Tube in it is characterized in that, in PVC in pipe or the stainless steel outside the pipe, and the glass fiber bundle that is compounded with steel pipe or radially twines.

Tube section is circular in described, and is perhaps oval, perhaps polygonal.

The outer circle of steel tube section for adapting with it of pipe is perhaps oval in described being compounded in, perhaps polygonal.

The utility model compared with prior art has following advantage and effect: adopt such scheme, can make the pressure pipe that has after compound possess higher capacity, decay resistance and less flow resistance preferably, and weight is moderate, and cost is low, can be used in water conservancy, the construction of hydropower plant, help reducing engineering cost, prolong pipeline working life, reduce operating cost, also can be widely used in simultaneously in the line transportation engineering of other industries such as chemical industry, metallurgy, in fact be one desirable the pressure composite pipe to be arranged.

Embodiment

Below in conjunction with accompanying drawing the utility model is described further.Be not limited thereto but hold within the utility model.

The utility model provides has the composite pipe of pressure to comprise interior pipe, wherein in pipe be pvc pipe 1, in PVC, outside the pipe 1, be compounded with steel pipe 2, and pipe 1 and steel pipe 2 cross sections be circle in the PVC, as Fig. 1.

The utility model provides that to press the interior pipe of composite pipe be Stainless Steel Tube 3, outside the pipe 3, is compounded with steel pipe 2 in stainless steel, and their section be circle, as Fig. 2.

The interior pipe that the pressure composite pipe is arranged that the utility model provides is a pvc pipe 1, and pipe 1 outer radial twines glass fiber bundle 4 in PVC, and the cross section of pipe 1 is a circle in the PVC, as Fig. 3.

Claims

1. one kind has the pressure composite pipe, comprises interior pipe, in it is characterized in that pipe for pvc pipe or Stainless Steel Tube, in PVC in pipe or the stainless steel outside the pipe, the glass fiber bundle that is compounded with steel pipe or radially twines.

2. according to claim 1 have a pressure composite pipe, it is characterized in that described in tube section for circular, perhaps oval, perhaps polygonal.
