Description

一种复合不锈钢管
技术领域
本发明涉及一种复合不锈钢管，属于不锈钢制品技术领域。
背景技术
不锈钢钢管是一种中空的长条圆形钢材，主要广泛用于石油、化工、医疗、食品、轻工、机械仪表等工业输送管道以及机械结构部件等。另外，在折弯、抗扭强度相同时，重量较轻，所以也广泛用于制造机械零件和工程结构。也常用作生产各种常规武器、枪管、炮弹等。
现有的不锈钢钢管，内壁容易被腐蚀，维修工作量大。
发明内容
本发明的目的是克服现有技术的不足之处，提供一种复合不锈钢管。
本发明的复合不锈钢管，包括中空不锈钢内管和套在中空不锈钢内管上的铝合金外管，所述的中空不锈钢内管的内壁设有防腐蚀涂层，所述的铝合金外管的外壁设有耐磨涂层。
所述的中空不锈钢内管和铝合金外管的横截面形状相同，均为圆形、正方形或者不规则圆形。
本发明的复合不锈钢管，具有如下技术效果：1）防腐蚀涂层使得不锈钢内壁防腐蚀；2）铝合金外管使得管总重量减少、焊接性提高；3）耐磨涂层起到耐磨的作用。
附图说明
图1为本发明的复合不锈钢管的截面图。
其中，1为中空不锈钢内管，2为铝合金外管，3为防腐蚀涂层，4为耐磨涂层。
具体实施方式
如图1所示，本发明的复合不锈钢管，包括中空不锈钢内管1和套在中空不锈钢内管1上的铝合金外管2，所述的中空不锈钢内管1的内壁设有防腐蚀涂层3，所述的铝合金外管2的外壁设有耐磨涂层4。所述的中空不锈钢内管1和铝合金外管2的横截面形状相同，均为圆形、正方形或者不规则圆形。
上面结合附图对本发明的实施方式作了详细的说明，但是本发明不限于上述实施方式，在所属技术领域普通技术人员所具备的知识范围内，还可以在不脱离本发明宗旨的前提下做出各种变化。

Claims (2)

1.一种复合不锈钢管，其特征在于，包括中空不锈钢内管和套在中空不锈钢内管上的铝合金外管，所述的中空不锈钢内管的内壁设有防腐蚀涂层，所述的铝合金外管的外壁设有耐磨涂层。
2.根据权利要求1所述的复合不锈钢管，其特征在于，所述的中空不锈钢内管和铝合金外管的横截面形状相同，均为圆形、正方形或者不规则圆形。
