热轧无缝钢管的技术指标及生产标准

信息来源:kitweet.com江西11选5 | 发布时间:2019年12月10日

  热轧无缝钢管的交货状态一般是热轧状态经过热处理后进行交货。热轧无缝钢管在经过质检后要经过工作人员的严格的手工挑选,在质检后要进行表面涂油,然后紧接着是多次的冷拔实验,热轧处理后要进行穿孔的实验,如果穿孔扩径过大就要进行矫直。在矫直后再由传送装置传送到探伤机进行探伤实验,最后贴上标签、进行规格编排后放置到到仓库当中。一般用无缝钢管是用10、20、30、35、45等优质碳结钢16Mn、5MnV等低合金结构钢或40Cr、30CrMnSi、45Mn2、40MnB等合结钢热轧或冷轧制成的。10、20等低碳钢制造的无缝管主要用于流体输送管道。45、40Cr等中碳钢制成的无缝管用来制造机械零件,如汽车、拖拉机的受力零件。一般用无缝钢管要保证强度和压扁试验。热轧钢管以热轧状态或热处理状态交货;冷轧以热处理状态交货。
