Abstract
The utility model provides a composite stainless steel tube, which comprises a hollow stainless steel tube inner tube and an aluminum alloy outer tube which is sleeved on the hollow stainless steel tube inner tube, wherein an anti-corrosion coating is arranged on the inner wall of the hollow stainless steel tube inner tube, and a wear-resistant coating is arranged on the outer wall of the aluminum alloy outer tube. The composite stainless steel tube has the beneficial effects that 1 the anti-corrosion coating prevents a stainless steel inner wall from being corroded; the aluminum alloy outer tube reduces total weight of the composite stainless steel tube and improves welding performance; and 3 the wear-resistant coating plays the wear-resistance role.
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 the industrial transportation pipe lines such as oil, chemical industry, medical treatment, food, light industry, machinery instrument and machine structural parts etc.In addition, when bending, twisting strength are identical, weight is lighter, so be also widely used in manufacturing machine part and engineering structure.Also be commonly used for and produce various conventional weapons, 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 is to overcome the deficiencies in the prior art part, and a kind of composite stainless steel pipe is provided.
Composite stainless steel pipe of the present utility model, comprises hollow stainless steel inner tube and is enclosed within the aluminum alloy outer tube in hollow stainless steel inner tube, the inwall of described hollow stainless steel inner tube is provided with corrosion resistant coating, and the outer wall of described aluminum alloy outer tube is provided with wear resistant coating.
Described hollow stainless steel inner tube is identical with the shape of cross section of aluminum alloy outer tube, is circle, square or irregular cycle.
Composite stainless steel pipe of the present utility model, has following technique effect: 1) corrosion resistant coating makes stainless steel inner wall anti-corrosive; 2) aluminum alloy outer tube makes to manage gross weight minimizing, weldability improves; 3) wear resistant coating plays wear-resisting effect.
Accompanying drawing explanation
Fig. 1 is the sectional view of composite stainless steel pipe of the present utility model.
Wherein, 1 is hollow stainless steel inner tube, and 2 is aluminum alloy outer tube, and 3 is corrosion resistant coating, and 4 is wear resistant coating.
