Abstract

The utility model pertains to the technical field of pipes, and particularly relates to a metal compound pipe. The inner liner of the utility model is made of seamless steel pipe with a thin wall, while the outer wall thereof is made of a thermal insulation and shock elimination pipe. The compound pipe has good mechanical performance, high intensity, high pressure resistance, lower cost and light weight and can spare the effect of heat expand and coldness contract and can be used as the ideal pipeline of building water supply.

Description

Metal composite pipe

Technical field

The utility model belongs to the tubing technical field, is specifically related to a kind of metal composite pipe.

Technical background

But all there is following several deficiency in popular in the market tubing: 1. homogenous material pipeline, this kind pipeline requires too high to wall thickness, thereby causes cost of material too high.2. composite material conduit, this kind pipeline compound solid but can't be heat insulation with insulation and be affected by thermal expansion and contraction bigger.Along with the raising day by day of living standards of the people, people are also more and more higher to the requirement of quality of the life in daily life.Find that by market survey adopting other material conduit to substitute traditional Coating Steel Pipe is current domestic popular trend in industrial civil building water supply and residential project drinking water supply system,

Summary of the invention

The purpose of this utility model is to provide a kind of metal composite pipe little, in light weight, that intensity is high, cost is low that is affected by thermal expansion and contraction.

The metal composite pipe of the utility model design is made up of liner and the outer wall that is compound in the liner outside, and wherein, liner is the thin-wall seamless Stainless Steel Tube, and outer wall is that inner shafts is to the insulation shock-absorbing pipe that is evenly distributed with groove.Its structure as shown in Figure 1.The tube material of this structure can be protected the metal tube-surface not to be damaged and can reach the requirement of heat-insulation and heat-preservation.

In the utility model, adopt the insulation vibration damping material as the coupling core type composite pipe of outer wall, PE for example, its inner shafts is to be equally distributed groove, retention air in this groove.The thickness of outer wall is determined by the size of pipe diameter.General thickness is 1.5-3mm, and depth of groove is 0.5-2mm.The thickness of gapless stainless steel tube is also determined with the pipe diameter size, generally be can be 0.5-1mm.Liner and outer wall are closely compound.

The utility model metal compounded pipe is compared with pipeline commonly used in the market has the relatively more outstanding advantage in following two aspects:

1, adopt the thin-wall seamless Stainless Steel Tube as liner metal tube guaranteed that the mechanical property of steel pipe is good, intensity is high, characteristics that can be withstand voltage, and in light weight, cost is low.

2, after pipeline outer-layer (PE pipe) is subjected to the high strength material fixing the interior metal pipe still can stretch arbitrarily mobile, so be not affected by thermal expansion and contraction.

3, meet the environmental protection sanitary standard of country about pipeline.

Therefore, this pipeline can guarantee the water quality that supplies water for a long time, is that a kind of desirable building supply water, the good pipeline of household decoration.

Description of drawings

Fig. 1 is the utility model structural drawing.

Number in the figure: 1 is liner, and 2 is outer wall, and 3 is groove.

Embodiment

As the water supply line of building, its specification is 4 writing brushes, 6 writing brushes, 8 writing brushes etc., and thickness is 0.7mm.Its liner is a gapless stainless steel tube, and outer wall adopts polyethylene (PE), and thickness is 2mm, and its inner shafts is 1mm to depth of groove, promptly gets the required metal composite pipe that arrives.

Pipeline is embedded in the concrete, treat after the concrete hardening concrete to be broken, this moment pipeline outer-layer compound PE pipe rupture because of sticking together with concrete, but liner thin-wall seamless Stainless Steel Tube plays effect because of the lotus root core type design of outer PE pipe uniqueness, but still remains intact harmless.

Claims

1. a metal composite pipe is characterized in that being made up of liner and the outer wall that is compound in the liner outside, and wherein, liner is the thin-wall seamless Stainless Steel Tube, and outer wall is that inner shafts is to the insulation shock-absorbing pipe that is evenly distributed with groove.
