Wing unions & swivel joints have been used in the oilfield services for almost a century.
Originally branded under the Weco® names, the wing unions & swivel joints have built a worldwide reputation with generation to generation of field operators.
The Weco® names have developed into generic terms for the products themselves, after so many years usage, rather than an individual brand or manufacturer.
The applied technologies of wing unions & swivel joints have proven their high level of efficiency in extremely severe flow conditions such as very high pressure & flowrates, high & low temperatures, multiphase flow, erosive and corrosive agents, vibration in pumping piping systems, etc.
Wing unions are also often referred to as hammer unions, hammer lug unions or Weco® dependent upon the customer or manufacturer.
Whatever name is used, they are the most common quick connection method for joining piping components together in a temporary system.
