本文整理了美标Class系列 ANSI B16.5钛法兰(WN,SO,BL,LWN)带颈对焊法兰、带颈平焊法兰、盲板、长高颈法兰近似重量查询表。
- 规格：DN15~DN600，NPS1"~24" Class150#，Class300#，Class600#，Class900#，Class1500#，Class2500#
- 密度：钛材密度按4.51计算，若要计算其他材质法兰重量，根据钛法兰重量除以4.51再乘以相应材质密度则可得到近似重量
- 法兰标准：ANSI B16.5 ASME B16.5
WN钛法兰(带颈对焊法兰)近似重量表：密度4.51g/cm3，尺寸标准ANSI B16.5/ASME B16.5
