Features
Thermal stress of pipe line is to be absorbed due to its sufficient allowable axial movement on elongation and contraction.
With union type end connection, it allows fast diassembly by losening the union nut only.
With simplified design,it requires minim space in the piping sys-tems, and there is no need of expansion U-bend.
Earthquake resistant design; Allowable axial movement-Elongation contraction.
Internal stop design prevents the expension portion from being removed.
