Piston accumulators are just one of the many types of equipment available for deep, subsea oil and gas applications. These new high-pressure piston accumulators for the oil and gas market have working pressure ratings up to 30,000 psi and capacities of 160+ gallons. Blowout prevention systems (BOPs), well-head control panels, “Christmas” trees, and other emerging drilling systems are available as well.
These custom units can be constructed of stainless or carbon steel and are available with a variety of finish options to operate in almost any environment. The high-pressure piston accumulator 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: 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, AS1210 – Australian Certification.
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 lets you operate equipment in virtually any environment.
The piston accumulator capability includes 1.5- to 25-in. bore sizes with capacities up to 200 gal. All are custom designed to fit a specific application.
