Method to connect control line to an externally testable port (19-Jan-2010)
When making pressure connections one of the preferred methods is to utilize metal to metal seals. Our customers usually require us to pressure test all connections. One of the popular metal to metal seal choices is the AutoClave Engineers Medium Pressure (AEMP) connection. As designed and manufactured by AutoClave (and others) the connetion is not easily tested. There is prior art for adding a secondary seal to test the metal to metal seal. Baker Hughes has developed its own variation which works well when this can be manufactured integral to the part. This is referred to as Externally Testable AEMP. Applications are arising which require connecting tubing to an AutoClave style connection. This connection will have to be tested. Our preferred method is the Externally Testable AEMP. Baker Hughes currently manufactures and installs "crossover" assemblies which facilitate the connection of control lines to AEMP connections. This introduces additional connections which must be tested. The crossover fittings also have a minimum length so they are not always suitable for every application. This invention shows how to connect tubing to a manufacured part which can later be connected to and tested with the Externally Testable AEMP.
