欧洲法兰标准EN 1092-1关于计算的思考

Thinking about the Calculation for Europe Flange Standard en 1092-1

欧洲法兰标准,EN 1092-1,带颈对焊法兰,当对接厚度小于标准规定的最小厚度,某些设计人员根据条款5.6.1 NOTE 2,认为应该对其进行计算。经过研究、查证,发现此种现象,可以通过削边对接厚度来匹配,并查阅相关标准,给出了标准法兰不需要计算的依据。

Europe flange standard,EN 1092-1,weld-neck type,some engineer suppose shall be calculate for wall thickness less than minimum value given in standard according to clause note 2 of 5.6.1.After research and investigate,this situation could reduce the flange wall thickness to match.And give evidence without calculation as per reference standard.
