Bladder hydraulic accumulator - 3.8 - 49.2 l, max. 459 bar | ASME
The shell is made of chromium-molybdenum steel. The seamless shell has been designed and made as per ASME VIII Div 1 U stamped. All of Olaer's shells have undergone pressure testing. Optionally available is an extra hydro-pneumatic pressure test on the entire accumulator both with or without any particular inspection authority. Also available upon request is certification for all key pressure loaded parts.
They have a single coat primer finish as standard. Also available are special paints. The bladder has a fully enclosed construction with a broad range of elastomers. For assembly of fluid port, the accumulators include a built in high-flow port and poppet valve assembly along with an anti-extrusion ring.
For safety, it should be noted that each of the gas-loaded accumulator is a pressurised vessel. It is therefore recommended to provide safety consideration to applications which are using them.
