Due to the nature of the challenging operating environment, #floatinghoses are subject to damages caused by marine growth, sea water, weathering, impact from boat hulls and propellers. All parts of floating hoses get impacted: external rubber, internal lining and #flanges. If not addressed at an early stage, the damages may lead to a loss of buoyancy or to a catastrophic oil and fuel spillage putting marine life and the environment in danger. Replacement of floating hoses incurs high expenses and downtime. Repairing them with durable elastomeric materials eliminates the need for an expensive and time-consuming replacement. In the next couple of minutes, we will demonstrate how to install a new full-face rubber flange gasket using #Belzona2111 – a flexible, abrasion-resistant polyurethane elastomer. For more information about Belzona 2111, click here: https://www.belzona.com/en/products/2000/2111.aspx First, prepare the surface by removing the damaged parts of the existing gasket, marine growth and any loose parts utilizing handheld tools. Abrade the sound surface of the existing gasket. Use ¾” plywood sheets to create a former. Cut the mold at least 2” larger than the inner and outer diameter of the flange face. Use the cut-out wooden former to measure and create a gasket out of a rubber sheet. Abrade the surface of the rubber gasket to ensure an optimal product bond. Before the product application, abrasive blast the surface of the flange face to achieve a near white metal finish. For this repair, we used glass media to reach the desired result. Once the surface is fully prepared, prime it with Belzona 2911 conditioner. The surface of the rubber gasket needs to be conditioned as well. Use a short-bristled brush to work the material well into the roughened surface. Thoroughly mix the base and solidifier of Belzona 2111. Apply the mixed material to the flange face surface and the rubber gasket surface. Push the material well into the roughened profile to ensure an optimal bond with the surface. Immediately, place the wetted side of the rubber gasket onto the wetted side of the flange face. Place the wooden former over the rubber gasket and secure it in place using clamps. Allow the Belzona material to cure fully. Remove the clamps and the wooden mold. Remove the excess rubber material following the contour of the inner and outer diameters of the flange face. Cut out the rubber covering the stud holes. The installation of a new gasket with Belzona 2111 is now complete!
