Abstract
The utility model relates to a composite water tube, which comprises a plastic core tube and stainless steel externally lined on the outer part of the plastic core tube. The utility model is characterized in that a thermal barrier coating is arranged between the plastic core tube and the stainless steel, and the stainless steel is tightly coated and combined on the plastic core tube and is welded and grinded into a tube shape. The utility model has the advantages of simple manufacture technology, simple structure and low manufacture cost.
Description
The utility model relates to a kind of water pipe.
The stainless composite water pipe of existing plastic core pipe outer lining all is earlier Stainless Steel Tube to be enclosed within on the plastic core pipe, by drawing, sizing Stainless Steel Tube tightly is enclosed within on the plastic core pipe then.This kind composite water pipe be owing to will make Stainless Steel Tube in advance, but also will pass through operations such as drawing, sizing, so has manufacturing process complexity, shortcoming that manufacture cost is high.
Goal of the invention of the present utility model is to provide that a kind of manufacturing process is simple, simple in structure, the composite water pipe of low cost of manufacture.
The utility model is achieved in that and comprises plastic core pipe, the outer lining stainless steel outside plastic core pipe, and its specialization is to be provided with heat insulating coat between plastic core pipe and stainless steel, the tight inclusion of stainless steel on plastic core pipe and through welding, be polished into tubulose.The effect of heat insulating coat is when preventing to weld, and high temperature is to the influence of plastic core pipe.
Compared with the prior art the utility model owing to need not make Stainless Steel Tube in advance, and need not drawing during moulding, therefore, has that manufacturing process is simple, simple in structure, advantage of low manufacturing cost.
Fig. 1 is a structural representation of the present utility model.
Now in conjunction with the accompanying drawings and embodiments the utility model is described in further detail:
As shown in the figure, the utility model comprises plastic core pipe 1, the outer lining stainless steel 2 outside plastic core pipe 1, its specialization is to be provided with heat insulating coat 3 at plastic core pipe 1 and 2 of stainless steels, and stainless steel 2 tight inclusions are on plastic core pipe 1 and through welding, be polished into tubulose.
