Abstract
The utility model discloses a steel-plastic composite pipe which relates to composite pipes and comprises a plastic inner pipe and a stainless steel outer pipe arranged at the outer wall of the plastic inner pipe. A foaming layer is arranged between the plastic inner pipe and the stainless steel outer pipe, and a plastic layer is arranged at the outer surface of the stainless steel outer pipe. The composite pipe organically combines the stainless steel outer pipe with the plastic inner pipe which is good in corrosion resistance, not easy to rust, and environment protective and health, and scale is not easy to form on the plastic inner pipe, thereby having small fluid resistance and friction coefficient. The stainless steel outer pipe is firm in structure and has good press resistance capability. Besides, the foaming layer has heat preservation and thermal insulation effect, and the plastic layer improves the anti-corrosion, anti-static and flame-retardant capability and widens the application field.
Description
Technical field
The utility model relates to a kind of composite pipe, relates in particular to a kind of steel-plastic composite pipe.
Background technique
Plastic tube is the chemical building material that high-tech is composited, in recent years, advantages such as plastic tube is in light weight with it, good corrosion resistance, tensile strength is big, friction factor is little, fluid resistance is little, convenient transportation, installation are simple are in China's fast development, yet in extensive use, also expose shortcomings such as the plastic tube structure is insecure, anti-pressure ability difference simultaneously.Though at present steel tubular goods can overcome the existing above-mentioned shortcoming of plastic tube, shortcomings such as that steel tubing exists under special conditions of manufacture is perishable, easily get rusty, heat insulating ability difference, and after long-term the use, the easy incrustation of inner tube wall, fluid resistance is big.How both being combined, is those skilled in the art's urgent problems.
The model utility content
At the problem that above-mentioned prior art exists, the utility model purpose is to provide a kind of steel-plastic composite pipe, can effectively solve above-mentioned problems of the prior art.
The technical solution of the utility model is: a kind of steel-plastic composite pipe comprises plastic inner pipe and is installed in the stainless steel outer tube of plastic inner pipe outer wall that be provided with foaming layer between plastic inner pipe and the stainless steel outer tube, the outer tube outer surface of stainless steel is provided with plastic layer.
As preferably, described plastic layer is polyethylene layer, polypropylene layer, polyvinyl chloride layer or PVC layer.
The beneficial effects of the utility model are: modern design, structure are rationally, plastic inner pipe and stainless steel outer tube are combined, plastic inner pipe good corrosion resistance, non-corrosive, environmental protection sanitary, and be difficult for incrustation after long-term the use, fluid resistance is little, friction factor is little, and the stainless steel outer tube structure is firm, anti-pressure ability is strong.In addition, foaming layer has increased function of heat insulation, and anticorrosive, antistatic, anti-flame retardant property that plastic layer has improved has enlarged application area.
Description of drawings
Fig. 1 is the utility model embodiment's a cross-sectional structure schematic representation.
Embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
As shown in Figure 1, a kind of steel-plastic composite pipe comprises plastic inner pipe 1 and is installed in the stainless steel outer tube 3 of plastic inner pipe 1 outer wall that be provided with foaming layer 2 between plastic inner pipe 1 and the stainless steel outer tube 3, stainless steel outer tube 3 outer surfaces are provided with plastic layer 4.Described plastic layer 4 is polyethylene layer, polypropylene layer, polyvinyl chloride layer or PVC layer.
The utility model combines plastic inner pipe 1 and stainless steel outer tube 3, plastic inner pipe 1 good corrosion resistance, non-corrosive, environmental protection sanitary, and be difficult for incrustation after long-term the use, fluid resistance is little, friction factor is little, and stainless steel outer tube 3 sound constructions, anti-pressure ability are strong.In addition, foaming layer 2 is formed after injection machine injects foaming by the foam material that is filled between plastic inner pipe 1 and the stainless steel outer tube 3, has increased the utility model function of heat insulation, plastic layer 4 has improved anticorrosive, antistatic, anti-flame retardant property, has enlarged application area.
