缩小接箍外径对油管抗滑脱强度影响的试验分析
Tests and Analysis of Reduction of Coupling OD VS Tubing Anti- slippage Strength
-
摘要: 对Φ73mm×5.51mmNU N80油管采用了三种外径接箍进行有限元计算与滑脱强度试验,分析了接箍外径缩小后对连接强度的影响以及失效形式。Abstract: Calculation with FE method and slippage strength tests are conducted, using couplings with three ODs applied on the Φ73mm×5.51mm NU N80 tubing to analyze the relationship between reduction of coupling OD and the joining strength and the failure form as well.
