The Lockbox piston accumulator design addresses issues of costly, time-consuming, and complicated offshore accumulator service by removing the issue of corroded large threads.
Lockbox piston accumulator design addresses issues of costly, time-consuming, and complicated offshore accumulator service. Traditional piston accumulators have a threaded retaining ring that holds the endcap into housing. Corrosion of the large thread fuses the ring and housing together, complicating disassembly and reassembly. The Lockbox design removes the issue of corroded large threads, allowing for simpler service of accumulators right on the rig. They can be disassembled, inspected, have seals replaced. Reassembly is quick using standard tools.
