Description

Continuous fiber reinforced polyethylene pipe and pipeline system

Technical Field

The utility model relates to the technical field of pipeline production, and particularly discloses a continuous fiber reinforced polyethylene pipe and a pipeline system.

Background

At present, polyethylene pipelines have been widely used in such fields as water supply, gas, sewage disposal, communication cables, and the like. Along with the increasing complexity of the application environment of the polyethylene pipeline, the compressive strength requirement of people on the polyethylene pipeline is also higher. For this purpose, some techniques wind a fibrous layer on a polyethylene pipe to increase the strength of the polyethylene pipe, as shown in the patent application CN 202022553073.7. Pipelines often require multiple pipelines to be joined together as they are laid to form a pipeline system. However, the end surfaces of the two polyethylene pipelines are rough after the fiber layers are arranged, so that the butt joint end surfaces of the two polyethylene pipelines are not easy to seal; and, even after setting up the fibrous layer, the link strength of pipeline still can not satisfy the demand.

Disclosure of utility model

The present utility model has been made to solve the above problems, and provides a continuous fiber reinforced polyethylene pipe and a pipe system capable of securing the strength of the pipe connection end and making the connection between pipes tighter.

The aim of the utility model is achieved by the following technical scheme: the polyethylene-based composite material comprises a polyethylene-based pipe, polyethylene thickening layers respectively coated on the outer walls of two ends of the polyethylene-based pipe, continuous fiber layers wound on the outer walls of the polyethylene-based pipe and positioned between the two sections of the polyethylene thickening layers, and fiber thickening layers respectively wound on the outer sides of two ends of the continuous fiber layers.

The outer surface of the polyethylene thickening layer is flush with the outer surface of the fiber thickening layer.

The length of the polyethylene thickening layer is 50-100 mm.

The continuous fiber layer and the fiber thickening layer are both glass fibers or basalt fibers.

The pipeline system comprises a plurality of the continuous fiber reinforced polyethylene pipes which are sequentially connected end to end, and two adjacent continuous fiber reinforced polyethylene pipes are fixed through a flange structure.

Further, the flange structure comprises two flanges which are respectively arranged on the connecting ends of two adjacent continuous fiber reinforced polyethylene pipes, a screw rod which is connected with the two flanges, and a locking nut which is arranged on the screw rod.

As another preferable scheme, a sealing gasket is arranged between the butt joint end surfaces of two adjacent continuous fiber reinforced polyethylene pipes.

As another preferable scheme, the outer sides of the butt joint ends of two adjacent continuous fiber reinforced polyethylene pipes are sleeved with protective sleeves.

Compared with the prior art, the utility model has the following beneficial effects: the polyethylene thickening layer and the fiber thickening layer are arranged on the outer side of the connecting end of the polyethylene pipe, so that the strength of the connecting end of the polyethylene pipe can be improved; the polyethylene thickening layer not only ensures the strength of the connecting end of the connecting polyethylene pipe, but also ensures the flatness of the butt joint end surfaces of the polyethylene pipe, so that the sealing performance of the butt joint of two pipes is better.
