Our Capabilities

Power

Turbine crossover bellows type expansion joints: From the early pioneering days of Westinghouse and General Electric, ADSCO’s type expansion joints have been supplied as original equipment and refurbishments to every size power plant running today.

Our Capabilities

Petroleum

FCCU: Fluid catalyst cracking units, are probably the most demanding application for any expansion joint in your plant. Significant pressures, extreme operating temperatures, chemical compatibility with the bellow’s wetted surfaces and erosion from the catalyst can make these quite a challenge.

Our Capabilities

Chemical

Chemical compatibility and temperature are key issues we find in dealing with chemical process applications. ADSCO can make metal bellows out of almost any weldable and bendable material. From relative common stainless steels to the Hastelloy’s and Inconel’s, we’ve made it.

Our Capabilities

District Heating & Cooling

Ask us anything! ADSCO is the abbreviation for American District Steam Company! We invented this application. As manufacturers of both bellows and slip type expansion joints, we can supply the best expansion joint for the applications. Steam, condensate, chilled water, air, gas etc you name it.
