Excessive steam and condensate leakage in sootblower feed tubes can lead to high operating and maintenance costs. We developed a solution to maintain constant concentric packing load to assure a tight seal at all times. A wave spring provides immediate response to dynamic conditions during the entire operating cycle, even compensating for packing wear.
Our live-loaded packing design provides concentric loading without requiring torque setting of gland nuts and springs. The corrosion-resistant, solid-ring graphite foil packing is offered for the live-loaded gland to provide superior service. It is a flexible, all-graphite ribbon foil packing containing corrosion inhibitors, with no resin binders or organic fillers. It features high-density, conical ring-style packing, preformed to dimensions and configuration with interlocking construction for maximum strength.
