Parker Increases Piston Accumulator Pressure Ratings up to 30,000 psi; 160+ Gallon Capacities to Meet 10,000-Ft. Deep Sea Drilling Requirements

ROCKFORD, Ill. - Parker Hannifin Corporation, the global leader in motion and control technologies, announces the capability to provide high-pressure piston accumulators for the oil and gas market. With working pressure ratings up to 30,000 psi and capacities of 160+ gallons, Parker accumulators meet the tough demands of deep, subsea oil and gas applications, including blowout prevention systems (BOPs), well-head control panels, "Christmas" trees and other emerging drilling systems.

"These custom designed units can be constructed of stainless or carbon steel and are available with a wide variety of finish options that provide our customers the flexibility to operate their equipment in any environment," notes Mike Schubert, Marketing Manager, Parker Hannifin Corporation, Global Accumulator Division. "Additionally, with this new high pressure piston accumulator capability, our customers can operate in depths greater than 10,000 feet below the ocean surface."

The following pressure vessel certifications are available for all Parker piston accumulators:

o ABS - American Bureau of Shipping

o DNV - Det Norske Veritas (E-101 regulations)

o PED - European Pressure Equipment Directive "CE" Marking

o ASME - American Society of Mechanical Engineers

o CRN - Canadian Registration Number

o AS1210 - Australian Certification

o Multiple certifications on a single vessel

In addition to high pressure-rated units for subsea applications, Parker offers piston accumulators rated to below -40°F. This increased flexibility at extreme temperature ranges offers GAD's customers the ability to operate their equipment in virtually any environment.

Parker's piston 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.
