UPVC Flange
Detachable Connection for Equipment Access
This fitting provides detachable connections between pipes and equipment or valves. Flange connections allow easy installation, inspection, and replacement of piping. You do not need solvent cement for this connection. Bolts provide the sealing force. This makes maintenance much simpler. You can disconnect and reconnect without damaging the pipe ends. We offer both slip-on and threaded-neck types. Slip-on flanges work well for lower pressure systems. Threaded-neck flanges handle higher pressures. You will use these at chemical plant equipment interfaces, pump inlet and outlet connections, and filter connections. Any location needing frequent disassembly benefits from this fitting.
