Pipeline with reinforced winding of continuous fiber weaving

Technical Field

The utility model relates to the technical field of pipelines, in particular to pipeline of winding reinforcing is woven to continuous fibers.

Background

In the present year, the requirements of China on the safety, long-term stability and long-term stability of systems such as electric power, water supply and drainage, communication, traffic and the like are higher and higher. The traditional materials such as steel pipes, iron pipes and the like are easy to conduct electricity, are easy to corrode in a humid environment, have short service life, have high maintenance cost and the like, and are gradually replaced by pipelines made of novel materials. The common novel material pipeline is including drawing around FRP pipe way, PVC, PP, PE etc. draw around FRP pipe way and generally design the fibre felt layer at the internal and external surface, but the fibre felt layer can not the batching drum, must two or the multichip is constituteed, can lead to vertically having the seam of unevenness like this, and the stretch-proofing ability is weak, receives external factor pipeline and easily breaks, and plastic conduit rigidity is low, intensity is poor, easy damage. To this end we propose a continuous fiber braided twisted reinforced pipe to solve the above problems.

SUMMERY OF THE UTILITY MODEL

The utility model provides a pipeline of winding reinforcing is woven to continuous fibers, its purpose is low, intensity is poor in order to solve plastic conduit rigidity, easy damaged problem.

In order to achieve the above object, the utility model provides a pipeline of winding reinforcing is woven to continuous fibers, the pipeline includes core pipe, interior tie coat from inside to outside in proper order, weaves fibrous layer, winding fibrous layer and outer protective layer, the winding fibrous layer includes first hoop winding fibrous layer, axial winding fibrous layer and the second and encircles the fibrous layer, by weaving fibrous layer to all having soaked the resin between each layer of second hoop winding fibrous layer.

Preferably, the adhesive layer is a resin layer.

Preferably, the weaving angle of the weaving fiber layer is 90-120 degrees.

Preferably, the axially wound fiber layer is located between the first and second hoop wound fiber layers.

Preferably, the first hoop winding fiber layer is wound clockwise, the axial winding fiber layer is tightly wound along the axial direction of the core pipe, and the second hoop winding fiber layer is wound anticlockwise.

Preferably, the crossing angle of the first annular winding fiber layer and the second annular winding fiber layer is 90-120 degrees.

Preferably, the wall thickness of the pipeline is 3.0-5.5 mm.

The above technical scheme of the utility model has following beneficial effect:

the utility model discloses the core pipe surface is woven and is twined continuous fiber, has strengthened the thickness of core pipe, weaves the fibrous layer with certain angle along core pipe circumference from one end to the other end, has strengthened the hoop rigidity of core pipe, and the winding fibrous layer has contained hoop and axial winding fibrous layer, and wherein, axial winding fibrous layer is tightly locked by first hoop winding fibrous layer and second hoop winding fibrous layer, has strengthened the axial strength of core pipe.

The utility model discloses core pipe surface is even paints one deck resin, can strengthen the bonding strength of weaving layer and core pipe after the resin solidification, prevents that the fibrous layer from taking place the displacement, weaves fibrous layer and first hoop winding fibrous layer, first hoop winding fibrous layer and axial winding fibrous layer, axial winding fibrous layer and second and all has soaked the resin material between the fibrous layer, can make after the resin solidification fixed very firm between each layer.

The utility model discloses improve the rigidity and the intensity of pipeline effectively, prolonged the life of pipeline.
