Abstract
The utility model relates to a composite pipe which is composed of a two-layer structure, wherein, the inner layer is a metal layer inner bag, and the outer layer is an insulating layer, wherein, the inner layer is preferred to the stainless metal layer inner bag, and the outer layer is preferred to the plastic insulating layer. The utility model can be suitable for sanitary water-supply conveying pipelines, etc. used in industries such as building, medical treatment, pharmacy, food processing, etc., and the utility model is especially suitable for occasions which need thermal insulation. The utility model has the advantages of good thermal insulating performance, no scale deposit, no pollution, convenient installation, good sealability, long service life, low cost, beautiful appearance, etc.
Description
The utility model relates to a kind of composite pipe, refers to a kind of pipeline that is composited by several different materials especially.
As everyone knows, the galvanized pipe that adopts usually now has many disadvantages.At first be very easily get rusty, easy scaling, can cause secondary pollution to drinkable water, the eater is caused adverse influence, simultaneously its outer surface also easily get rusty, stained etc., aesthetic property is very poor, can not be fit to modern house and otherwise needs.Also have shortcomings such as transportation inconvenience, heat insulation property difference in addition.If use all steel pipe, though can solve the part defective of galvanized pipe, still have difficulty and cost height be installed, reach shortcomings such as heat insulation property difference.
The purpose of this utility model is to provide a kind of composite pipe, has that wholesomeness is good, insulation and characteristics such as easy for installation.
The purpose of this utility model realizes by following structure: the (see figure 1) that this composite pipe is made up of two-layer structure: internal layer is a metal layer inner bag 1, and skin is a thermal insulation layer 2.
Composite pipe of the present utility model can engage easily with commercially available copper joint, convenient and swift and good airproof performance.
Embodiment, Fig. 1 are the utility model structural representations.
The preferred stainless metal layer inner bag 1 of the internal layer of composite pipe of the present utility model.
The thermal insulation layer 2 of outer preferred plastics, these plastics be elasticity good toughness, plastics that intensity is high most preferably, as the PVC plastics etc.
Composite pipe of the present utility model is because the preferred stainless inner bag of its internal layer, so have the plurality of advantages of all steel pipe, and, long service life good, pollution-free etc. as scaling not, wholesomeness.Because its skin is a plastic layer, so possessed the not available characteristic of many all steel pipes again,, cost good, easy for installation as heat insulation property hangs down and reaches characteristics such as attractive in appearance again.The conveyance conduits such as health water supply that use in the industries such as composite pipe of the present utility model can be applicable to build, medical treatment, pharmacy and food processing are especially applicable to the occasion that needs insulation.
The major advantage of the utility model composite pipe be heat insulation property good, not scaling, pollution-free, easy for installation and good airproof performance, long service life, cost is low and advantage such as attractive in appearance.
Claims (3)
1. composite pipe, it is characterized in that being made up of two-layer structure: internal layer is the metal layer inner bag, and skin is a thermal insulation layer.
2. composite pipe as claimed in claim 1 is characterized in that internal layer is stainless metal layer inner bag.
3. composite pipe as claimed in claim 1 is characterized in that skin is the thermal insulation layer of plastics.
