Induction Bolt Heating

After years of research and development, Xtreme Bolting Services, Inc., introduced the patent-pending Xtreme Bolting Machine (XBM) at the Power-Gen show in November 2006. The XBM has several advantages over the Induction Heating method that has been the industry standard for bolt removal during an outage. Our system is lightweight, economical to use, simple to operate, and robust in construction. Size and weight are just two small advantages of the system, but when one considers that a single, 85 lb machine can remove 6 bolts at a time, the money saved on reduced outage time quickly becomes the biggest advantage of all. The Xtreme Bolting Machine and the services from Xtreme Bolting Services offered in conjunction with TTI have continued to gain popularity since its introduction.
