An oil and gas production company’s test chamber, used to evaluate downhole drilling components, needed heaters that could withstand pressures up to 35,000 pounds psi and temperatures up to 500° F. The company was using 52 sets of band heaters that aligned with temperature requirements, but were breaking under the pressures in the chamber. The screw terminals on some of the heaters would break off even with little torque during testing, and some of the heaters did not fit securely in the chamber after thermal expansion. - Chromalox redesigned the company’s band heaters by eliminating barrel nut assembles and replacing them with ear fittings that would allow for new hardware including screws, springs, nuts and washers.
