ASME B36.10M · W = (OD − WT) × WT × 0.0246615
如何阅读规格表
- NPS(公称尺寸)以英寸表示,DN 是对应的公称直径。同一 NPS 的外径固定,与 SCH 无关。
- SCH(SCH10、SCH40、SCH80 …)决定壁厚。STD、XS 和 XXS 是较早的壁厚等级:NPS 10 及以下 STD 等于 SCH40,NPS 12 及以上为 9.53 mm。
- 重量为平口钢管理论重量,按 ASME B36.10M 公式计算:W = (OD − WT) × WT × 0.0246615 kg/m。部分印刷表的数值舍入可能相差 ±0.01 kg/m。
每捆重量
米重 × 单支长度 × 支数。以 61 支 NPS 1½ SCH40(48.3×3.68 mm)、长 6 米的一捆为例:4.05 kg/m × 6 m × 61 = 1482 kg,与该捆标牌上的重量一致。
锅炉管与其他标准
锅炉管和换热器管(ASTM A179、A192、GB/T 3087)以及 EN 或 GOST 钢管按外径×壁厚订货,而非 NPS 和 SCH。请在计算器中输入外径和壁厚。
