Abstract:The assembly process of flareless pipe joints is very important for the
sealing performance of hydraulic pipeline system. Based on the theory of
contact mechanics, a theoretical model of the assembly process of pipe
joints is established to simulate the extrusion molding process of
flareless pipe joints. It is found that tightening torque is an
important factor affecting the sealing performance of pipe joints. By
comparing the changes of the contact stress between the sleeve and the
pipe joint under different … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
