BANDLOCK CLOSURES

GD Engineering is a world leader in the manufacture of quick opening closures. Our GD Bandlock™ 2 is the original and benchmark design for global high pressure applications with over 20,000 units in operation worldwide.

GD Bandlock™ 2 Closures provide horizontal or vertical access to any pressure vessel in seconds. Compared with other quick-opening closures they can be operated safely at remarkable speed — any size of unit can be opened or closed in less than a minute, with no special tools required.

Computer-aided technology has played a large part in the design of Bandlock™ 2. The main pressure loaded sections have been designed to save weight by employing finite element analytical techniques and proof testing by strain gauges, while still adhering to primary pressure vessel code requirements.

The tried and tested locking band mechanism which gives the range its name is a duplex stainless steel conical thrust ring fitted between the door and hub, transmitting the pressure load uniformly around the full 360° circumference of the hub.
