2019版的ASME IX中QW-402.30—A decrease of 10% or more in the specified width of the ligament between tube holes when the specified width of the ligaments less than the greater 10mm of three times the specified tube wall thickness.我有以下问题:1.The specified width of the ligament between tube holes是否理解为咱们常说的孔桥宽度?2.如果说孔桥宽度大于10mm或3倍壁厚中的较大者,那适用范围就是孔桥宽度大于等于10mm吗?希望各位同行前辈解释一下,谢谢啦
