如下就是钢管直径DN、NB、OD三者的对照表，这个表格在平时的工作中应用率很高，如有需要可以联系我，给你传份更详细的对照表。 提供钢管直径DN、NB、OD的区别钢管公称外径表示方法对照表word文档在线阅读与免费下载，摘要:钢管直径DN、NB、OD的区别/钢管公称外径表示方法对照表钢管从业人员在平时的工作和学习中经常会遇到DN、NB、OD等不同的钢管直径的表示方法，非钢管专业人员很容易将这个三个直径混淆。 下面是我对这三个钢管直径的理解，与大家 …

Nominal Pipe Size (NPS) is a North American set of standard sizes for pipes used for high or low pressures and temperatures. Pipe size is specified with two non-dimensional numbers: a nominal pipe size (NPS) for diameter based on inches, and a schedule (Sched. or Sch.) for wall thickness.

Nominal Bore (NB) is the European designation equivalent to NPS is DN (diamètre nominal/nominal diameter/Durchmesser nach Norm), in which sizes are measured in millimeters. NB is also frequently used interchangeably with NPS.

2019年3月14日 · DN ——以公制 (mm)为基准，称为DN (metric unit)公制单位，DN即nominal diameter公称直径。 NB ——以英制 (inch)为基准，称为NB (inch unit)英寸单位，NB即nominal bore公称内径。 OD ——OD即outside diameter外径。 欧标 ——对应欧标内螺纹。 DN——以公制 (mm)为基准，称为DN (metric unit)公制单位，DN即nominal diameter公称内径。 NB——以英制 (inch)为基准，称为NB (inch unit)英寸单位，NB即nominal bore公称内径。 OD——OD …

2014年12月6日 · Wall thickness dimensions for standard steel, plastic and other pipe schedules for NPS and DN designation in metric British unit are shown in tables as per ASME/ANSI B36.10M and API 5L standard.

The nominal bore is loosely related to the i/d of the pipe, there are different wall thicknesses or schedules available for each size, the o/d stays constant for each NB, the heavier the schedule of pipe the smaller the bore. Here we have both imperial and metric units. Imperial
