AIR Springs Supply has released Pronal’s Pronair range of inflatable products designed to quickly seal external leaks on pipes and tanks. The sealing units can inflated to a maximum standard working pressure of 5 bar, depending on application.
They can be quickly installed on-site to provide immediate assistance in accidents or emergencies. The inflatable belts and pads are wrapped around the leaking pipe or secured over other leaking surfaces, then inflated to press their sealing surface against the leak.
They are compact to minimise storage space and allow installation in confined areas. They are suitable for applications which require compatibility with hydrocarbons. Pronair units have reinforcement strips along each edge, to which adjustable fastening straps are fixed. The sealing surface in contact with the pipe or tank is reinforced with a sheet of rubber. They are fitted with an inflation stem for compressed air well within standard industrial pressures of five to seven bar.
