Finite Element Analysis of Casing Threaded Connectors


Designing threaded connectors for steel casing pipes is a highly challenging problem, requiring designers to optimize multiple parameters such as taper angle, pitch, load and stab flank angles and thread heights. The casings are subject to extreme internal and environmental pressures, and if the threaded connections fail, the cost can run into millions of dollars and cause severe environmental damage. GB Tubulars uses simulation and physical testing to verify the design of their casings. Through benchmarks tests, they verified that simulation accurately correlated with physical testing results, enabling them to save time and money by increasing simulation use.
