Quick disconnect system

08 October 2007

A system which maintains high levels of joint integrity, while allowing quick connection and disconnection of pipe work, is now available from Garlock. Designed for connecting conical flanges on pipe work from 18mm diameter to 410mm diameter, Garlock's Quick Disconnect System (QDS) allows fast and easy installation and removal of equipment from process or test applications.

Supplied with two conical flanges, a Helicoflex seal and an articulated collar, the QDS is available in four classifications - Class 150 for a non-magnetic lightweight coupling allowing tightening up to 150N/mm; Class 300 for low pressure applications; Class 500 for medium pressures; and Class 1,000 for high pressure and temperature applications, including steam.

The QDS clamping collar offers excellent mechanical efficiency. Each collar set has been designed to provide optimum distribution of tightening force by adapting the rollers to a corresponding flange diameter.

For applications where automatic coupling and disconnection are required (for example, in radioactive environments), Garlock has developed a QDS and Helicoflex seal suitable for remote handling. The inherent design of QDS makes it particularly suitable for remote handling applications, as no twisting torque is applied to the connections.

Garlock is able to provide detailed technical data to support selection regarding temperature relative to pressure limitations. Up to 400°C can be used with the QDS.
