Company History

In 1877 the American District Steam Company (ADSCO) designed and built the country's first district heating system in Lockport, New York. To compensate for thermal expansion of distribution piping conveying steam, Adsco engineers invented the first expansion joint.

Since 1877 Adsco has grown to become one of the leading suppliers of expansion joints with customers around the globe.
