The leading technology in pigging systems gives you 360 degree cleaning coverage with no pipe or tube damage. This new system from Hydro Kleen combines industrial diamond coatings with bi-directional technology to de-coke and de-scale safely. The "Pinnacle" is especially effective in furnace/heater convection and radiant sections where long runs with 180 degree bends are not properly cleaned with steam air or long radius appendage type pigs.\r\n\r\nThe "Pinnacle" pigging system is the only system currently available that is capable of cleaning SQUARE-PLUG-MULE type headers with absolutely no alterations. Best of all, "Pinnacle" is completely chemical free and safe for the environment.
