Abstract
The utility model provides a kind of composite stainless steel pipe, be made up of steel pipe body (10) and link, described steel pipe body (10) forms by managing (1) in the hollow stainless steel of integration and being enclosed within the aluminum alloy outer tube (2) of managing on (1) in hollow stainless steel, in described hollow stainless steel, the inwall of pipe (1) is provided with corrosion resistant coating (3), and the outer wall of described aluminum alloy outer tube is provided with wear resistant coating (4).The utility model has following technique effect: 1) corrosion resistant coating makes stainless steel inner wall anti-corrosive; Wear resistant coating plays wear-resisting effect; 2) aluminum alloy outer tube makes pipe gross weight reduce, and during connection, card pressure is convenient; 3) each fastener for connection is convenient, can effectively connect different composite stainless steel pipes by card press tool card pressure connecting tube, in addition, steel pipe body is in itself and seal ring contacting point and be wave structure with the both sides of seal ring contacting point, better tightness after card pressure, stability is higher.
Description
Technical field
the utility model relates to a kind of composite stainless steel pipe, belongs to Stainless Steel Products technical field.
Background technique
Stainless-steel pipe is a kind of rectangular circular steel of hollow, is mainly widely used in industrial transportation pipe line and the machine structural parts etc. such as oil, chemical industry, medical treatment, food, light industry, machinery instrument.In addition, when bending, twisting strength are identical, lighter in weight, so be also widely used in manufacturing machine part and engineering structure.Also be commonly used for and produce various conventional weapon, gun barrel, shell etc.
Existing stainless-steel pipe, inwall is easily corroded, and maintenance load is large.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art part, provides a kind of composite stainless steel pipe.
Composite stainless steel pipe of the present utility model, be made up of steel pipe body (10) and link, described steel pipe body (10) forms by managing (1) in the hollow stainless steel of integration and being enclosed within the aluminum alloy outer tube (2) of managing on (1) in hollow stainless steel, in described hollow stainless steel, the inwall of pipe (1) is provided with corrosion resistant coating (3), the outer wall of described aluminum alloy outer tube is provided with wear resistant coating (4), described link is made up of bent connecting tube (5) and the seal ring (6) be located in bent connecting tube (5), described bent connecting tube (5) is enclosed within steel pipe body (10), described seal ring (6) is sealed between bent connecting tube (5) and steel pipe body (10), described steel pipe body (10) is in itself and seal ring (6) contacting point and be wave structure with the both sides of seal ring (6) contacting point.
In described hollow stainless steel, pipe (1) is identical with the shape of cross section of aluminum alloy outer tube (2).
Composite stainless steel pipe of the present utility model, has following technique effect:
1) corrosion resistant coating makes stainless steel inner wall anti-corrosive; Wear resistant coating plays wear-resisting effect.
2) aluminum alloy outer tube makes pipe gross weight reduce, and during connection, card pressure is convenient;
3) each fastener for connection is convenient, can effectively connect different composite stainless steel pipes by card press tool card pressure connecting tube, in addition, steel pipe body is in itself and seal ring contacting point and be wave structure with the both sides of seal ring contacting point, better tightness after card pressure, stability is higher.
accompanying drawing explanation
Fig. 1 is the sectional view of composite stainless steel pipe of the present utility model.
Fig. 2 is the plan view of composite stainless steel pipe of the present utility model.
Fig. 3 is the connection diagram of composite stainless steel pipe of the present utility model.
Wherein, 1 is pipe in hollow stainless steel, and 2 is aluminum alloy outer tube, and 3 is corrosion resistant coating, and 4 is wear resistant coating, and 5 is bent connecting tube, and 6 is seal ring, and 10 is steel pipe body.
Embodiment
As Fig. 1, 2, shown in 3, composite stainless steel pipe of the present utility model, be made up of steel pipe body (10) and link, described steel pipe body (10) forms by managing (1) in the hollow stainless steel of integration and being enclosed within the aluminum alloy outer tube (2) of managing on (1) in hollow stainless steel, in described hollow stainless steel, the inwall of pipe (1) is provided with corrosion resistant coating (3), the outer wall of described aluminum alloy outer tube is provided with wear resistant coating (4), described link is made up of bent connecting tube (5) and the seal ring (6) be located in bent connecting tube (5), described bent connecting tube (5) is enclosed within steel pipe body (10), described seal ring (6) is sealed between bent connecting tube (5) and steel pipe body (10), described steel pipe body (10) is in itself and seal ring (6) contacting point and be wave structure with the both sides of seal ring (6) contacting point.In described hollow stainless steel, pipe (1) is identical with the shape of cross section of aluminum alloy outer tube (2).
When connecting each composite stainless steel pipe, as long as received on another composite stainless steel pipe by the link cover of a composite stainless steel pipe, re-use card press tool, the annular groove of card press tool is aimed at seal ring (6) annular projection place, firmly card pressure can be fixed.
By reference to the accompanying drawings mode of execution of the present utility model is described in detail above, but the utility model is not limited to above-mentioned mode of execution, in the ken that art those of ordinary skill possesses, can also make a variety of changes under the prerequisite not departing from the utility model aim.
