SPX has launched its Bandlock 2 Quick Opening Closure to meet the specific needs of the oil and gas market. The Bandlock 2 Closure is specifically designed for global high pressure applications in the oil and gas and petrochemical industries. It gives quick and safe access to pipelines and pressure vessels including pig launchers and receivers, hydrocyclones, filters, strainers, separators, coalescers and metering skid systems. It can be used in horizontal, vertical, inclined or declined installations and requires no special tools to operate.
The Bandlock 2 Closure is manufactured to international standards and in full compliance with ASME VIII Div. 1 UG 35. The fail-safe door is held in place by a 360° duplex stainless steel locking band that is in compression and visible at all times, even in the locked position.The self-energizing fully moulded lip seal uses a stainless steel anti-extrusion spring and can be manufactured from a wide range of materials to meet highly demanding operating conditions. At zero pressure the seal is completely pressure-tight and has full vacuum capability.
The closure is designed so it is not possible to open the door with residual pressure inside the vessel. To ensure safe operation, a hand-operated pressure warning screw integrated into the closure mechanism prevents the door from being unlocked until it is confirmed that the vessel’s internal pressure has been relieved.
