Abstract

The utility model discloses a composite structure of plastic and copper pipes, particularly a new plastic and copper composite pipe, which overcomes the defects that a plastic pipe has poor strength and easy breakage and a full copper pipe has high cost, high use expenditure, etc. The utility model mainly comprises an inner layer and an outer layer. The outer layer is a plastic outer layer and the inner layer is a copper inner layer. The plastic outer layer and the copper inner layer are adhered by hot melt adhesive. The strength of the composite pipe of the utility model is stronger than the plastic pipe with corrosion resistance and pressure resistance. The outer layer is the plastic and thus the utility model has the functions of alkalinity and acidity resistance and corrosion resistance.

Description

New shape copper composite pipe

The utility model relates to the composite structure of a kind of plastics and copper pipe, is a kind of new shape copper composite pipe.

At present, all kinds of water supply, heat supply, chemical system all be unable to do without tubing.And presently used pipeline all exists following deficiency: in the pipe material that for example uses in water supply network, easy scaling in the galvanized pipe pipe when using tap water, often has iron rust to occur, and causes the secondary pollution of water, and its installation labor intensity is big; Plastic tube intensity is undesirable; Copper pipe is the cost height again, and aluminium-plastic composite pipe is also uneconomical.

The purpose of this utility model is to provide at above-mentioned situation that a kind of cost is low, intensity is high, and is unlikely to cause the new shape copper composite pipe of the secondary pollution of water in use.

The copper composite pipe of moulding of the present utility model is tubular structure, and it includes inside and outside two-layer, and its skin is a plastic outer layer, and its internal layer is the copper internal layer, and is bonding by hot melt adhesive between plastic outer layer and the copper internal layer.

This copper composite pipe of moulding has following advantage: when water supply network uses, can not cause the secondary pollution of water, outer tube layer is plastics, and internal layer is a copper, and intensity is greater than plastic tube, and corrosion resistant, withstand voltage, and outer layer plastic has anti-acid resistant alkali, anticorrosive effect; The pipe network spreadable life is prolonged, and it has assembled the advantage separately of plastic tube and copper pipe, and it and novel pipe fitting accessory are used, and be easy for installation; On gas ductwork, use, because double-deck compound air feed that makes is safer; Use in heating network (low pressure hot-water heating heating range), owing to the physical features of copper, its decay resistance is better than galvanized pipe in the pipe network, and its skin has the plastics composite bed can play thermal effect again, reduces the loss in transmission and distribution network, i.e. health, energy-conservation again.

Below in conjunction with accompanying drawing technology contents of the present utility model and structure characteristic thereof are further described:

Accompanying drawing is the utility model structural representation.

Element numeral among the figure, 1, be plastic outer layer; 2, be the copper internal layer.

Referring to accompanying drawing, the copper composite pipe of moulding of the present utility model is tubular structure, and it includes inside and outside two-layer, and its skin is a plastic outer layer 1, and its internal layer is a copper internal layer 2, and is bonding by hot melt adhesive between plastic outer layer 1 and the copper internal layer 2.

The copper composite pipe of moulding of the present utility model, owing to be the pipe material that adopts above-mentioned technical pattern to be combined into, overcome easily defectives such as fracture and full copper pipe cost height, cost of use height of plastic tube intensity difference are arranged, its performance is better than other pipe material, and healthy all useful to environment and people is ideal green pipe material.

Claims

A kind of new shape copper composite pipe is tubular structure, and it is characterized in that: it includes inside and outside two-layer, and its skin is plastic outer layer (1), and its internal layer is copper internal layer (2), and is bonding by hot melt adhesive between plastic outer layer (1) and the copper internal layer (2).
