Abstract
The utility model relates to a water supply pipe, which is composed of an inner layer stainless steel pipe (1) and a plastic surface layer (2) which is joined and poured on the surface of the outer diameter of the inner layer stainless steel pipe (1). The utility model is characterized in smooth inner wall, large water flow velocity, no rustiness, no water damage generation, convenient treatment of tapping and connecting, good tightness, corrosion resistance, alkali and acid resistance, long service life, etc. The utility model is adapted to the green environmental protection index of food and water, and is mainly used in water supply pipes particularly drinking water pipelines for residents.
Description
The utility model relates to a kind of water pipe.
The water pipe of prior art has two classes: the first kind is a metal, normally seamless galvanized iron conduit, and its deficiency is that iron pipe easily gets rusty, easy-to-rust, working life is short, and the water-soluble water hygiene that influences of iron rust; Second class is a plastic water pipe, though non-corrosive is easily aging, bad mechanical strength, thereby working life is also short, partly plastic is harmful, so narrow limitation is arranged in its application of plastic water pipe: be used to carry mordant liquid as industrial, or for agricultural water, or interim transporting water etc.
Stainless steel is owing to be characterized in non-corrosive, smooth surface, and corrosion-resistant, long service life, but price height are generally used for daily goods and chemical production equipment etc.If adopt pure Stainless Steel Tube to make water pipe, though can overcome the deficiency of above two kinds of water pipes, satisfy the thickness that tapping connects but will make, its cost people are difficult to accept on the one hand, have also wasted a large amount of stainless steel materials on the other hand.
The purpose of this utility model is to overcome short, the deficiency such as unhygienic that supplies water in the working life of the above galvanized iron conduit and plastic tube, designs a kind of stainless steel waterpipe of lamination layer structure.
The purpose of this utility model is achieved in that and adopts Stainless Steel Tube as inner tube, annotates a plastic surface layer in its external diameter surface rank and constitutes.
The utility model, described plastic surface layer can be made by modified plastics.
The utility model has following characteristics:
1, internal layer is a stainless steel lining, inner wall smooth, and water velocity is fast, improves supply water height and water output; Non-corrosive, the unboiled water stain does not adapt to environmental protection drinking water index.
2, skin is the heavy wall plastic layer, is convenient to tapping and connects good seal performance; Corrosion protection, acid resistant alkali, long service life.
The utility model is described in further detail in conjunction with the accompanying drawings for following embodiment:
Fig. 1 is the utility model embodiment's structure principle chart, i.e. sectional elevation.
Among the figure, 1 is inner layer stainless steel tube, and 2 is plastic surface layer.
The production of this composite stainless steel water pipe, at first select for use suitable stainless pipe 1 as inner tube, on specialized apparatus and mould, adopt rank to annotate drawing craft and make a plastic layer 2 on its outer surface then, plastic layer 2 can select for use modified plastics as main raw material.The described suitable stainless pipe of this example is meant the stainless pipe according to the determined various diameters of different usage requirements, various wall thickness.
The utility model is mainly used in water supply line, particularly resident's drinking water pipeline.
Claims (2)
1, a kind of composite stainless steel water pipe is characterized by: the plastic surface layer of being annotated on its external diameter surface by inner layer stainless steel tube (1) and rank (2) constitutes.
2, composite stainless steel water pipe according to claim 1 is characterized by: described plastic surface layer (2) is the modified plastics layer.
