一、低中压锅炉用无缝钢管 低中压锅炉用无缝钢管是采用优质碳素结构钢制造的,具有综合力学性能好的特点。 1.主要用途 钢管主要用作制造各种结构的低中压锅炉过热蒸汽管、沸水管及机车锅炉用过热蒸汽管、大烟管、小烟管和拱砖管。 2.形状、尺寸、交货状态 钢管截面形状为圆形,分为热轧和冷拔(轧)无缝钢管两种。 低中压锅炉用过热蒸汽管、沸水管的外径尺寸范围为10～426mm,壁厚范围为1.5
First, the low and medium pressure boiler seamless steel pipe Low and medium pressure boiler seamless steel pipe is made of high quality carbon structural steel, with good mechanical properties. 1. The main purpose Pipe is mainly used for the manufacture of various structures of low and medium pressure boiler superheated steam pipe, boiling water pipes and superheated steam locomotive boiler pipe, smoke pipe, small pipe and arch pipe. 2. Shape, size, delivery status Steel pipe cross-section shape is round, divided into hot-rolled and cold drawn (rolled) seamless steel pipe two. Low and medium pressure boiler with superheated steam pipe, the outer diameter of the boiling water pipe size range of 10 ~ 426mm, the wall thickness of 1.5
