ADSCO Manufacturing

From EverybodyWiki Bios & Wiki

ADSCO Manufacturing LLC[1] is an American manufacturer of metal bellows and slip-type expansion joints for the steam, petroleum, chemical and power production markets. Products include bellows, slip-type, rectangular, externally pressurized, toroidal, refractory lined and pressure balanced expansion joints, and custom expansion joints for extreme pressure, movement, temperatures, diameters and media. The company also offers custom expansion joints designed to withstand extreme pressure, movements and temperatures, with non-standard diameters and for use in a variety of applications.

ADSCO’s first predecessor, the Holly Steam Combination Company, is credited with introducing district heating[2] and slip-type expansion joints.

ADSCO was founded by Birdsill Holly[3], an inventor whose concept of distributing steam through underground pipes to heat structures in an immediate city area evolved into the system known as district heating. In 1877, he established the Holly Steam Combination Company.[4]

After buying out Holly’s patents on the system, the company began setting up franchises for heating plants in cities across the US, becoming the first steam producer to commercially distribute district heating from a central heating system.[5] The first system was installed in Lockport, NY, followed by similar systems in Auburn and Garden City, NY and Dayton, OH.

In 1881, Holly Steam reorganized and changed its name to American District Steam Company. This new company purchased patent rights from Holly Steam, along with any inventions that Holly had made over the past five years.

Some of these products are still in use by ADSCO today. Holly’s variator, which was designed to absorb pipeline expansion and contraction caused by steam surge, is the earliest forerunner of ADSCO slip-type expansion joints[6]. The bellows joint was developed for applications not suitable for expansion joints.

In 1955, the company changed its name to ADSCO Industries and began making acquisitions to round out its product line of expansion joints, heat exchangers and fabricated plates. Acquisitions included Farrar & Trefts, Inc., a manufacturer with expertise in the chemical, oil, gas and process industries; four companies that made and sold steel and industrial supplies; and the Alberger Heater Div. of Howard Iron Works, which manufactured heat exchangers and special machinery.

In 1955, ADSCO joined other companies to found the Expansion Joint Manufacturers Association (EJMA)[7], an organization setting standards in expansion joint quality and production.

In 1957, ADSCO and its Farrar & Trefts and Alberger Divisions became part of Yuba Mfg. In 1968, Yuba was acquired by Standard Prudential Corp. Standard sold ADSCO’s operations in 1972 to an investor group, which renamed the company ADSCO Mfg. Corp.

In 1987, Holly’s district heating system in Lockport, NY received a National Mechanical Engineering Heritage site designation[8] from the American Society of Mechanical Engineers (ASME)[9].

In 2020, ADSCO was acquired by a management group of investors and renamed ADSCO Manufacturing LLC.
