Stainless Accumulators / One Piece Bladder Type

Stainless Steel HydrAcc bladder type accumulators are popularly for use in oil and gas industry exploration and production shut-in systems. Small HydrAccs achieve this requirement. Suspension or counterbalancing has required large and heavy components; when converted to hydraulic linear actuators or cylinders attached to hydraulic and hydro pneumatic accumulators there is always a weight and cost saving. Bladder type accumulators are not recommended for emergency standby power applications because when the fails it is not progressive and determinate, it is sudden and total.

Stainless steel housings from heavy walled stainless for Hi pressure injection systems, ex/eg. Methanol injection up to 15000 psi 1000Bars, Corrosion inhibitor/Amines and other special applications including Duplex Stainless (2205, F-51, UNS S31803) and Super Duplex Stainless (2507, UNS S 32750).

Part Numbers / Sizing

Information About: Part Numbers / Sizing

• The prefix "HAcc" inserted where "HydrAcc" is located denotes this design: i.e. gas inside one-piece molded bag.
• The number following the prefix that is followed by the letter "i" denotes the number of cubic inches nominal volume. Units of 16.39millilitres, there are 61 cubic inches in one liter.
• The B reference is the diameter followed by length of the one piece molded bag. This is also the spare part reference for a new bag / bladder.
• The number preceding the letter p is the design pressure, this should be used for working pressures up to 85% of the p figure assuming that the system relief valve requires a 15% over pressure to fully open.
• The inch number denotes National Pipe Thread taper size.
• A letter needs inserting following the 316. The letter replaces ?? and denotes the elastomer of the membrane to be used ex/e.g. N = Buna-N / Nitrile, V = Viton,  etc.
