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.
