Abstract
The utility model discloses a stainless steel composite steel pipe which is characterized in that the inner layer is a stainless steel pipe, the outer layer is a carbon steel pipe, and the utility model is formed by cold drawing or expansion drawing after the outer layer is sheathed on the inner layer. The utility model can replace the stainless steel pipe, makes up for the use limitation of the carbon steel pipe and the nonmetal pipe, and has the advantages of corrosion resistance, high temperature resistance and pressure resistance.
Description
The utility model discloses a kind of compound steel pipe, is a kind of stainless steel composite pipe specifically.
Employed pipeline in the industries such as chemical industry, oil, light industry, printing and dyeing, medicine need have anti-corrosion property.Present Common Straight Carbon Steel and the nonmetallic pipe that uses, though both economical, anti-corrosion property is poor, maintenance load is big.Desirable anti-rotten pipeline is a Stainless Steel Tube, but the investment cost costliness.
The purpose of this utility model is to provide a kind of saving construction investment, has not only withstand corrosion, high temperature resistant but also stainless steel composite pipe that can pressure-bearing.
To achieve these goals, the utility model adopts following technological scheme: a kind of stainless steel composite pipe is characterized in that being made up of interior pipe and outer tube.
The utility model good effect is that composite steel tube can replace Stainless Steel Tube, not only withstand corrosion, high temperature resistant but can pressure-bearing, remedied the use narrow limitation of carbon steel tubing and nonmetallic pipe.The price of composite steel tube only is about 1/2nd of a Stainless Steel Tube, reduces the stainless steel consumption, and the cost of reducing investment outlay improves social economic benefit.
Below in conjunction with accompanying drawing the utility model is elaborated.
Fig. 1 is a kind of preferred embodiment structural representation of the utility model;
Fig. 2 is Fig. 1 embodiment's an axial sectional view;
Fig. 3 is the structural representation of the another kind of embodiment's tube opening of the utility model;
Fig. 4 is the structural representation of another embodiment's tube opening of the utility model.
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the utility model is outer with the thin-wall stainless steel 2 of seamless carbon steel tube 1 with internal layer, and through special cleaning, suit is after drawbench cold-drawn or expansion are pulled out compound.Composite pipe shaping again, machining form.Carbon steel can be used A as requested
3Type or 10
#, 20
#Deng grade of steel.Stainless Steel Tube comprises various different models.Pipe turned up 3 in the utility model pipe end was processed into, or the flat mouth 4 of inner and outer pipes, or interior rostrum is convenient to take over welding for outer tube 5.The utility model is applicable to all Stainless Steel Tube pipelines of industry such as chemical industry, oil, light industry, printing and dyeing, medicine.
Claims (2)
