Summary
Flexible coupling used to joint carbon steel and stainless steel pipes. Pipe diameter DN350 and above. Eliminates the need for bellows and flex connectors on mechanical piping systems.
-
-
Application
Installed on heating (LTHW), cooling (CHW,CON) mechanical systems, as well infrastructure water applications.
Provides limited linear and angular pipe movement at the pipe joint that can be used to compensate for thermal growth of piping systems, vibration attenuation, seismic, differential settlement and other applications requiring flexibility.
Can be used to create curved pipework.
Can be used in buried applications.
