Comparative Analysis of Sealing Performance Between Tapered/tapered and Spherical/tapered Structures of Special Threaded Joint of Oil Casing
摘要
Abstract
Finite element models are established for two most common premium threaded connection seal structures,namely,taper/taper seal and sphere/taper seal.According to the evaluation standard,all possible operating conditions were applied to the connections.The seal performance of the two structures was evaluated quantitatively with the seal intensity index.Anti-gluing performance of the two structures under the makeup condition was compared too.Finally,the experimental verification was carried out.The results show that the seal performance and anti-gluing performance of the spherical/taper structure are better than those of the taper/taper structure when the shoulder,thread shape,steel grade are same.Although taper/taper and spherical/taper seal structures can meet the requirements of seal criteria and test standards,spherical/taper structures have more advantages.关键词
