一般结构用钢管，简称结构管。
本标准代替GB/T8162-2008《 结构用无缝钢管》。本标准与GB/T8162-2008相比，主要变化如下：
结构管，此标准适用于一般结构、机械结构用无缝钢管，流体 无缝钢管 标准适用于输送流体的一般无缝钢管。聊城迪越钢管有限公司供应结构无缝钢管。它与结构无缝钢管的主要区别是流体无缝钢管逐根 
进行液压试验或进行超声波、涡流、漏磁探伤。因此，在压力管道钢管的标准选用上，不宜采用流体无缝钢管。无缝钢管表示方法为外径，壁厚，厚壁无缝钢管主要用于机械加工，煤矿，液压钢，等多种用途。厚壁无缝钢管的材质分为10#、20#、35#、45# 16Mn、27SiMn、12Cr1MoV、10CrMo910、15CrMo、35CrMo等。 厚壁无缝钢管分类——热轧厚壁无缝钢管、冷轧厚壁无缝钢管、冷拔厚壁无缝钢管、挤压厚壁无缝钢管、顶管。 结构用不锈钢无缝钢管（GB/T14975-1994）是广泛用于化工、石油、轻纺、医疗、食品、机械等工业的耐腐蚀管道和结构件及零件的不锈钢制成的热轧（挤、扩）和冷拔（轧）无缝钢管。
