由整块金属制成的,表面上没有接缝的钢管,称为无缝钢管。根据生产方法,无缝管分热轧管、冷轧管、冷拔管、挤压管、顶管等。按照断面形状,无缝钢管分圆形和异形两种,异形管有方形、椭圆形、三角形、六角形、瓜子形、星形、 带翅管多种复杂形状。最大直径达650mm,最小直径为 0.3mm。根据用途不同, 有厚壁管和薄壁管。无缝钢管主要用做石油地质钻探管、石油化工用的裂化管、锅 炉管、轴承管以及汽车、拖拉机、航空用高精度结构钢管。
无缝钢管(Seamless Steel Tube)是一种存在中空截面、周边不接缝的长条钢材.钢管具备中空截面,大批用作输送流体的管道,如输送石油、自然气、煤气、水及某些固体物...
