【山西衡泰尚(shang)盈貿易有(you)限責任公司】為您介(jie)紹DN125焊管：

購買厚(hou)壁(bi)焊(han)管(guan)需(xu)要注意(yi)哪些問題？首先要注意(yi)它的(de)厚(hou)度，管(guan)徑(jing)大(da)于(yu)0.0因為(wei)只有(you)這種壓力(li)大(da)，即使用力(li)拉也不會斷。要看它的(de)表面是(shi)否(fou)光滑。劣質(zhi)厚(hou)壁(bi)焊(han)管(guan)表面經(jing)常有(you)傷(shang)痕，有(you)的(de)有(you)細小裂紋，表面缺乏光澤。看到(dao)這樣(yang)的(de)焊(han)管(guan)，一定知道不是(shi)焊(han)管(guan)。
