All AMC rotary joints include an iridite/corrosion protection treatment. The flanges are unplated, polished and iridited. Other finishes and paint colors are available upon request. AMC also houses a complete refurbishment department for rotary joints, committed to restoring used rotary joints to ‘like new condition’. Our installation crew is always busy outfitting a new SNG vehicle full of waveguide assemblies and rotary joints. The quality control department is located in the center of operations at AMC, and includes several digital height gauges, calibrated surface plates, and a host of certified/calibrated inspection equipment. The engineering lab houses the electrical equipment including a Wiltron Network Analyzer, used to electrically check all components. Visit our site for info.
