Description

High-strength composite pipe

Technical Field

The utility model relates to a pipe fitting technical field specifically indicates a high strength composite pipe.

Background

The sleeve on the outer part of the existing cable is generally an insulating tube, and the insulating tube made of polyvinyl chloride material is usually selected. The polyvinyl chloride pipe has self-extinguishing property and flame retardancy, and the flame retardant property of the polyvinyl chloride pipe can meet the use condition of an electrical casing.

However, the existing polyvinyl chloride pipe has poor toughness and ductility, is easy to break and crack, and is more easily damaged in a low-temperature environment. During engineering construction, the cable is easy to collapse and deform or even block after being trampled or rolled, and cannot be used through normal threading, so that hidden troubles are left for safe use of the cable.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve foretell various problems, provide a simple structure, the compound pipe of high strength that resistance to compression is stronger.

In order to solve the technical problem, the utility model provides a technical scheme does: the utility model provides a high strength composite pipe, from interior to exterior is equipped with fire-retardant insulating layer, adhesive linkage one, metal level, adhesive linkage two and fire-retardant insulation strengthening layer in proper order, fire-retardant insulating layer with pass through between the metal level adhesive linkage one bonds, the metal level with pass through between the fire-retardant insulation strengthening layer adhesive linkage two bond, fire-retardant insulation strengthening layer includes skin, inlayer and is used for connecting inlayer and outer a plurality of connecting piece, pass through between inlayer and the metal level adhesive linkage two bond.

As an improvement, the material of the flame-retardant insulating layer is polyvinyl chloride.

As an improvement, the materials of the first bonding layer and the second bonding layer are both resin or thermosetting adhesive.

As an improvement, the metal layer is made of steel.

As an improvement, the outer side of the metal layer is coated with an anticorrosive material.

As an improvement, the outer layer, the inner layer and the connecting piece are all made of rubber and are integrally formed.

Compared with the prior art, the utility model the advantage lie in: when the utility model is used, the cable is arranged inside the flame-retardant insulating layer in the composite pipe, and the flame-retardant insulating layer can play a flame-retardant role; the arrangement of the metal layer can ensure that the ring stress and the tensile strength of the utility model are larger, which is beneficial to protecting the flame-retardant insulating layer in the composite pipe from being damaged; the arrangement of the flame-retardant insulation strengthening layer comprising the outer layer, the inner layer and the connecting pieces for connecting the inner layer and the outer layer can ensure that the external elasticity of the utility model is larger, and the metal layer can not be deformed irreversibly due to the external larger pressure; the utility model discloses the current potential safety hazard that the cable conductor brought because of the epidermis is ageing or damaged electric leakage has been alleviated in holistic setting, or current cable sleeve, tramples or rolls the back and sink easily and warp even jam when the engineering construction, and unable normal threading is used, has left the problem of hidden danger for the safe handling of cable.
