(Setting of first supports at the location beyond 0.5m could cause pipeline to bend by internal pressure and AV Expansion joints do not work properlly.) A；Dimension of pipe line B；Temperature Caution ● PVC, C-PVC 20 − 100mm (3/4 inch − 4 inch) within 0.5m within 0.5m Expansion joint First support ・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 disassembly, loosening the union nut only. ・With simplified design, it requires minimum, systems space in the piping systems, and there is no need of expansion U-bend. ・Earthquake resistant design; Allowable axial movement-Elongation contraction. ・Internal stop design prevents the expansion portion from being removed.
