Induction Bolt Heating / Stretching

Hand Carried Induction Power SupplyHeavy Hex Nut Heating With Induction Significantly Reduces Torque Required For Removal

Induction heating systems provided by Ajax TOCCO Magnethermic are ideal for heating heavy hex nuts commonly found in power generation, and petro chemical operations. Induction heating provides rapid, controlled, localized flameless heating to thermally expand heavy hex nuts that may be galled or corroded. Induction heating also quickly releases thread locking compounds. Although capable of temperatures exceeding 800C, only 200C or less is required for most heavy hex nut heating applications.

Industrial bolting and maintenance providers have reported being able to use standard pneumatic impact wrenches to remove heavy hex
nuts that previously required high torque hydraulic wrenches, thus increasing speed and reducing down time. Ajax TOCCO Magnethermic 5kW air cooled TOCCOtron AC induction heating power supplies can be hand carried to the job site. Compact hand held transformers allow operators to apply induction heating within confined areas. The 230/400/480V 1 or 3-phase input can be used at almost any job site.
