Abstract:
A secondary tubing containment system (10) is provided for a discharge tube (18) of a chemical metering pump (14) in a chemical addition system (12). One end of the discharge tube (18) is engaged in a fitting (20) on the metering pump (14), and the other end of the discharge tube (18) is engaged in a fitting (22). The containment system (10) includes a pair of coupling nuts (30, 32), a connector in the form of a Tee (34), two cylindrical tubes (36, 38), a pair of unions (40, 42), and a drain tube (44). The inside and outside diameters of the tubes (36, 38) are sized to allow the tube (38) to be slid or telescoped into the tube (36) to allow the length of the containment system (10) to be adjusted. The union (40) is configured to sealingly engage the tube (38) along the length of the tube (38) to accommodate the adjustment. This allows the containment system (10) to accommodate different lengths of discharge tube (18), as dictated by the particular chemical addition system (12) to which the containment system (10) is being assembled.
