通过对一大型90°弯头进行应力测试与爆破试验,得到了内压载荷下该厚壁弯头的外壁应力分布情况,确定了弯头的薄弱部位,并将试验结果与理论计算结果进行了比较。试验结果可为大型厚壁弯头的设计,制造及使用提供参考数据。
Through the stress test and blasting test on a large 90 ° elbow, the stress distribution on the outer wall of the thick elbow under internal pressure load is obtained, the weak part of the elbow is determined, and the experimental results and the theoretical calculation results Compare The test results can provide reference data for the design, manufacture and use of large thick-walled elbows.
