Expansion Joints

Gaskets, Belts and Expansion Joints for Gas Turbine Electric Power Plants

The first gas turbine electric power generation plant was built in Oklahoma City in 1949. It was the Belle Isle plant, which was owned and operated by Oklahoma Gas & Electric (OG&E) and 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 proved the concept, and hundreds of gas turbine power plants were built in the U.S. in the ‘60s, ‘70s, and ‘80s.

L. A. King Company, founded in 1956 in Oklahoma City, made gaskets, belts, and fabric expansion joints for Belle Isle, and for most of the GE turbine plants built in North America. In fact, L. A. King consulted on design specifications and many GE drawings specify L. A. King as the preferred supplier.

L. A. King never sold directly to GE, rather to manufacturers of auxiliary systems for gas turbine OEMs and power producers. Our customers were, and remain, some of the largest and most respected fabricators in the industry. Today, we continue to supply insulating and sound-deadening materials, gaskets, belts and expansion joints to OEMs building auxiliary equipment for power plants. We’ve earned our reputation for quality, on-time delivery, and fair prices. We work each day to live up to it.

Metallic Bellows Expansion Joints

Our designs accommodate a wide range of movements and service conditions. We offer round, rectangular, radius, single and double metered, single- and multi-ply, and camera corners. Corrosion resistant stainless steel, or any other alloy required. Need help with a design? Our engineers are here to help. Design and installation of internal flow liners, external covers, and operating hardware such as control and limit rods, hinges and gimbals are all available.

Fabric Expansion Joints 

L. A. King manufactures fabric expansion joints used in an array of industries such as power generation, refining, petrochemical, steel, pulp and paper, and cement. Expansion joints are utilized to connect systems/equipment such as an inlet plenum, exhaust plenum, stacks, silencers, diffusers, filter houses, diverters, dampers, evaporators, and coolers.

We have extensive experience with belts used in GE gas turbine power plants (Frame 5, Frame 6, Frame 7, Frame 9, and E-, F-, H- and J- class), both Inlet (cold side) and exhaust (hot side). We’ve been making B1100s and B1300s for decades.
