About L. A. King Co.

Belle Isle Power Plant

L. A. King Co. was founded in 1954 by Lawrence A. King, in Oklahoma City. We were a distributor of insulating and sound-deadening materials. Interestingly, the first gas turbine electric power generation plant in North America was built in Oklahoma City around this time. It was the Belle Isle Station plant, owned and operated by Oklahoma Gas & Electric (G&E). It utilized a 3.5MW GE turbine. At the time, gas turbines were being reliably used to propel airplanes, but the longer, continuous operating loads required for electricity generation had not been tested. Belle Isle Station proved the concept and hundreds of gas turbine power plants were built in the ‘60s, ‘70s and ‘80s. L. A. King Co. made gaskets and inlet and outlet ductexpansion joints (layered fabric and insulation) for the Belle Isle Station power plant. And we ended up suppling these items for most of the GE turbine plants built in North America. In fact, L. A. King consulted with GE on design specifications for flexible expansion joints(aka flex seals) used in GE turbine power plants. Many of these designs are still in use, detailed in GE specification documents with L. A. King listed as preferred supplier. L. A. King has rarely sold directly to GE. Our service and loyalty was and is to OEMs that manufacture auxiliary systems for gas turbine power plants...and to persons and companies that maintain and turn-around gas turbine power plants. For decades, until their demise, we were the #1 supplier of exhaust outlet duct belts to Braden Manufacturing, and of inlet duct expansion joints and flex seal belts and insulating pillows to J & G Steel. Our customers have been some of the most respected names in the industry. Today, we continue to supply insulating and sound-deadening materials, gaskets, belts and expansion joints/flex seals to OEMs building auxiliary equipment for power plants, and to power plant owners, operators and maintenance teams. We’ve earned a reputation for quality, on-time delivery, and fair prices. We work each day to live up to it.
