Conduit system with expansion coupling

摘要: A conduit system composed of insulated jacketed units each having an exposed male end and opposite integral female with internal seal ring carrying groove slidably sealingly receiving the adjacent unit thereby forming expansion coupling between units. flexible insulation surrounds coupled ends a sleeve jackets is sealed to jackets. The cores are thus surrounded or sleeves free expand contract withot opening up leakage paths buckling installed regardless temperature variations normally encountered by system.
