Abstract

本实用新型涉及一种泵用高耐磨性复合钢管,主要用于将搅拌混凝土输送至较高处,其特征在于:所述泵用高耐磨性复合钢管由内外两层钢管复合而成,其中内层为内层管(1),外层为外层管(2),所述内层管(1)的材质为60Mn,所述外层管(2)的材质为20Mn2。这种泵用高耐磨性复合钢管的内层管为60Mn材质,其耐磨性好,使得复合钢管寿命相对比较长,外层管为20Mn2材质,它具有一定的强度和韧性,主要用于保护内层管,一方面可延长内层管使用寿命,另一方面可保护内层管产生爆裂。

Description

泵用高耐磨性复合钢管
技术领域
本实用新型涉及一种泵用高耐磨性复合钢管,主要用于将搅拌混凝土输送至较高处。
背景技术
在修建高层建筑时,需要通过泵用钢管将搅拌混凝土输送至较高处。然而以往的泵用钢管均为单层结构,在运送搅拌混凝土时会受到较大的摩擦力,长时间使用容易导致钢管爆裂,不仅设备损耗大,而且有一定危险性。 
发明内容
本实用新型的目的在于克服上述不足,提供一种耐磨性好,寿命较长,韧性和强度较高,并且不易爆裂的泵用高耐磨性复合钢管。
本实用新型的目的是这样实现的:
本实用新型泵用高耐磨性复合钢管由内外两层钢管复合而成,其中内层为内层管,外层为外层管,所述内层管的材质为60Mn,所述外层管的材质为20Mn2。
与现有技术相比,本实用新型的有益效果是:
这种泵用高耐磨性复合钢管的内层管为60Mn材质,其耐磨性好,使得复合钢管寿命相对比较长,外层管为20Mn2材质,它具有一定的强度和韧性,主要用于保护内层管,一方面可延长内层管使用寿命,另一方面可保护内层管产生爆裂。
附图说明
图1为本实用新型泵用高耐磨性复合钢管的剖面结构示意图。
其中:内层管1、外层管2。
具体实施方式  
参见图1,本实用新型涉及一种泵用高耐磨性复合钢管,该复合钢管由内外两层钢管复合而成,其中内层为内层管1,外层为外层管2,所述内层管1的材质为60Mn,其耐磨性好,使得复合钢管寿命相对比较长,所述外层管2的材质为20Mn2,它具有一定的强度和韧性,主要用于保护内层管,一方面可延长内层管使用寿命,另一方面可保护内层管产生爆裂。

Claims (2)
