Parker Hannifin Corporation”s high-pressure piston accumulators for oil and gas applications support working pressure ratings up to 30,000 PSI and capacities of 160-plus gallons. The accumulators meet the demands of deep, subsea oil and gas applications, including blowout prevention systems (BOPs), well-head control panels, “Christmas trees,” and other emerging drilling systems. The accumulators are available with certifications for ABS (American Bureau of Shipping), DNV (Det Norske Veritas – E-101 regulations), PED (European Pressure Equipment Directive “CE” Marking), ASME (American Society of Mechanical Engineers), CRN (Canadian Registration Number), and AS1210 (Australian Certification). In addition to high pressure-rated units for subsea applications, Parker offers piston accumulators rated to below -40 F. Accumulator capability includes 1.5- to 25-inch bore sizes with capacities up to 200 gallons. All are custom designed to fit a specific application utilizing a total custom-based systems approach that includes application engineering and worldwide support. Currently, Parker lead-times for both stainless and carbon steel units are significantly shorter than the rest of the marketplace.
