Very Large Diameter Bandlock 2 Closures from Celeros Flow Technology

Global demand for essential products like water, gas and oil is growing, which means that pipelines and processing plants such as pressure vessels are getting bigger. To ensure continuity of supply and minimise downtime, maintenance teams need to gain safe and rapid access to critical plants that require servicing or repair.

Celeros Flow Technology offers Bandlock2 Closures in very large diameters – up to 100 inches – to meet this requirement. Manufactured by Celeros FT brand GD Engineering, very large diameter Bandlock2 Closures offer the same proven quick-opening mechanism and sealing design as their standard diameter counterparts. Despite their larger scale, there is no compromise on functionality: full access is still achievable in less than a minute.

Carla Connolly, Sales Director at GD Engineering, says: “Our Bandlock2 design has been up-scaled and engineered to enable operators to incorporate proven technology on very large diameter applications whilst experiencing the same ease of access enjoyed on smaller diameter pressure vessels. The ability to specify larger sized, quick-opening closures gives customers the potential to realise significant project savings in engineering time and cost by reducing the number of pressure vessels and associated pipework required for any given application.”

Larger Bandlock2 Closures feature a unique, self-energising lip seal with integral anti-extrusion spring and offer full vacuum capability. Safe operation is assured due to a hand-operated pressure warning screw, which is integrated into the closure mechanism and prevents the door being unlocked until it is confirmed that the vessel’s internal pressure has been relieved. Additional secondary safety features, such as mechanical key interlocks, can be fitted and integrated with control valve operations. In addition, the locking band can be seen at all times, which satisfies design code requirements and means that the operator can actually see that the door is securely closed and locked.

Bandlock2 Closures can be designed to open either horizontally or vertically and are manufactured in full compliance with ASME VIII Div. 1 UG 35.
