大口径方管是一种具有中空截面、周边没有接缝的长条钢材。钢管具有中空截面,大量用作输送流体的管道,如输送石油、天然气、煤气、水及某些固体物料的管道等。钢管与圆钢等实心钢材相比,在抗弯抗扭强度相同时,重量较轻,是一种经济截面钢材,广泛用于制造结构件和机械零件,如石油钻杆、汽车传动轴、自行车架以及建筑施工中用的钢脚手架等。用钢管制造环形零件,可提高材料利用率,简化制造工序,节约材料和加工工时,如滚动轴承套圈、千斤顶套等,目前已广泛用钢管来制造。

17.异型大口径方管是除了圆管以外的其他截面形状的大口径方管的总称。按钢管截面形状尺寸的不同又可分为等壁厚异型大口径方管(代号为D)、不等壁厚异型大口径方管(代号为BD)、变直径异型无缝  钢管(代号为BJ)。异型大口径方矩管广泛用于各种结构件、工具和机械零部件。和圆管相比,异型管一般都有较大的惯性矩和截面模数,有较大的抗弯抗扭能力,可以大大减轻结构重量,节约钢材。
