Victaulic Co of Kings Buildings, Dean Stanley Street, London, SW1. Telephone: Victoria 9796. Telegraphic Address: "Victaulic, Sowest, London".

The Victaulic pipe jointing system is designed for jointing steel, copper and stainless steel pipes. The system is primarily used to install fire protection systems (risers, sprinkler pipework etc.) and building services pipework - heating, chilled water, condenser, hot and cold water, potable water. The system is also widely used for industrial, petro-chemical, pharmaceutical, utilities, oilfield and mining applications.

  • The joint consists of two or more housings, a pressure responsive gasket, and nuts and bolts. The metal housing mechanically joins the two pipes together by locating into grooves, which are either cut or rolled into the pipe ends. This provides full end load restraint on the pipe joint while at the same time allowing some flexibility, which can be used to allow for thermal movement, misalignment, curved pipe runs etc., and eases installation of the pipework and fittings.
  • The gasket design is such that the system pressure helps seal the gasket onto the pipe, the greater the pressure the greater the sealing of the gasket. Similarly with vacuum systems, the gasket pressure will increase with negative pressure.
  • There are a variety of gasket materials to suit a wide range of fluids and media. The standard gasket for water services is grade "E", EPDM.
  • Groove ended fittings and valves are also available to provide a complete piping system. [1]

WWI The idea for the Victaulic joint was first conceived during the First World War by the Royal Engineers as a quick and easy method of jointing pipe.

The company that worked closely with the British War Department to develop piping systems for hydraulics was named the Victory Pipe Joint Co after the coupling it had engineered — known as the "victory joint" from early military uses.

1920 Private company.

1924 Moved its offices from 28, Victoria-street, London, S.W.I to larger premises in King's Building, Dean Stanley-street, Westminster, S.W.I.[2]

1925 the Victaulic Co – named by combining the words “victory” and “hydraulic” – was formed to market the concept of mechanical joining to the commercial piping industry. The company's headquarters were in Forks Township, outside Easton, Pennsylvania.

An early user of the system was the London Hydraulic Power Co, replacing old and installing new pipework with the Victaulic joint.

1928 Company made public.

1937 Listed Exhibitor - British Industries Fair. Victaulic joints of both bolted and toggle types, for shouldered or grooved steel pipes, also working model showing joints flexing under pressure. Johnson Couplings for plain end pipes, and Johnson Clamps for leaking cast iron joints or as keeper flanges - both used in anti air-raid precautions. (Stand Nos. D.601 and D.500) [3]

1937 Manufacturers of flexible pipe joints. "Victaulic" Flexible Pipe Joints and Couplings. [4]

1961 Pipe joint manufacturers, specialists in flexible "Victaulic" and "Viking". 600 employees. [5]
