Abstract

本实用新型公开了一种在化工、制药等行业普遍使用的钢管,在通常使用的不锈钢管的外壁设置有起增加强度作用的无缝钢管层。使用这种结构的管子,能大大减少不锈钢材料的用量,并能保证达到应有的耐腐蚀性和使用强度,能降低造价约50%,大大降低了用户的生产成本。

Description

钢管
本实用新型涉及到在化工、制药等行业普遍使用的不锈钢材料制成的钢管。
在化工、制药等行业,出于耐腐蚀的需要(如耐酸、碱)而大量使用不锈钢管。在使用过程中,为了使不锈钢管具有一定的强度,该不锈钢管的管壁都较厚,即不锈钢材料用量较大,因而这类不锈钢管的造价较高,使用户的生产成本也很高。
本实用新型的目的在于提供一种造价能大大降低的钢管。
为实现上述目的,本实用新型采用的技术方案为:在不锈钢管的外壁设置有起增加强度作用的无缝钢管层。
上面所述的无缝钢管层为优质碳素钢管或钛合金钢管。
本实用新型的优点是:使用这种结构的管子,在保持原有不锈钢管子耐腐蚀性能的情况下,能大大减少不锈钢材料的用量,并能保证达到应有的使用强度,能降低造价约50%,大大降低了用户的生产成本。
下面结合附图和具体实施方式对本实用新型作进一步详细的描述。
图1是本实用新型钢管的立体示意图。
如图1所示,所述的钢管内层为不锈钢管1,在不锈钢管1的外壁设置有一层起增加强度作用的无缝钢管层2。所述的无缝钢管层2可以是优质碳素钢管或钛合金钢管,主要起到增加整个钢管使用强度的作用,即先将焊制的不锈钢管1塞入无缝钢管2中,然后将不锈钢管1胀紧在无缝钢管2中即可。

Claims (2)

1、钢管,该钢管为不锈钢管,其特征在于:在不锈钢管的外壁设置有起增加强度作用的无缝钢管层。
2、如权利要求1所述的钢管,其特征在于:所述的无缝钢管层为优质碳素钢管或钛合金钢管。
