In the gas turbine power plant industry, bolted joints are critical on expensive rotating equipment. Thermal cycling and vibration result in settlement of flanges which can lead to gasket leaks. In worst case conditions, the power plant maintenance staff must schedule outages to tighten loose joints. Heico-Lock washers help avoid loosening problems. The washers are also available in Inconel and other alloys for high temperature areas. Heico-Lock washers are especially suited for gas and steam turbines, compressors, turbochargers, pumps, mixers, motors and gearboxes.
