ChangYuan Flex Co.’s double ball expansion joint is the pinnacle of flexible piping system technology. This new component has two spherical elements attached to a central spool to allow simultaneous axial, lateral and angular movements. Unlike traditional expansion joints, our double ball design is extremely flexible and can take on large multi-direction stresses within industrial piping networks. Its special configuration for the double ball expansion joint ensures good performance under high pressure and high temperature conditions and is therefore an indispensable solution for power plants,  plantas de processamento químico e refinarias de petróleo exigindo confiabilidade.

The superior stress distribution capabilities show the engineering prowess of ChangYuan double ball expansion joint. Utilising advanced computational fluid dynamics and finite element analysis our designers optimized the joint geometry to minimize localized stress concentrations. This results in double ball expansion joint which can accommodate more movements as well as being stronger and longer service life. Bounded load distribution among spherical elements permits a smoother operation with less wear even in extreme condition. In addition the double ball expansion joint is much smaller than traditional pipe loops and is therefore an ideal solution for installations with tight spatial constraints.

Materials choice matters greatly for the performance of ChangYuan’s double ball expansion joint. The spherical parts are made of good quality alloys like 316L stainless steel. The central spool material is selected based on application requirements – carbon steel for industrial standard or exotic alloys for chemical environments. Our graphene-infused PTFE composite sealing technology delivers unmatched leak prevention and durability. That particular attention to material science allows us to keep our double ball expansion joint functional even under harsh operational conditions.
