Hystat Accumulators

We are one of the UKs leading manufacturers of standard & bespoke accumulators, with complete manufacture since 1976.

With over 40 years of manufacturing experience, we have manufactured accumulators, gas bottles and pressure vessels for a vast range of applications and sectors, globally.

Our Accumulators, gas bottles and pressure vessels are supplied to numerous sectors including Oil & Gas (offshore & subsea), industrial, petrochemical, mining, medical, mobile, nuclear & defence. Through extensive knowledge, we can design and manufacture accumulators, gas bottles and pressure vessels to customer and third-party requirements in order to meet the project and application demand.

We have access to an extensive range of metallic, polymeric and elastomeric products in order to manufacture accumulators, gas bottles and pressure vessels that can meet the most difficult of application demands.

We are able to offer various level indication option depending upon the requirement. Typically the level indication can include visual displays, 4-20mA level transmitters & proximity switches. Level indication is available for topside and subsea applications in order to monitor internal volumes of nitrogen and fluid.

Piston Accumulators are manufactured in-house therefore shorter lead times are available.

We can also offer a range of spares including seal kits, burst discs, clamps and brackets.

Mixing Bottle/Pressure Vessel/Liquid Bottle

Our Mixing Bottles/Pressure Vessels/Liquid Bottles are supplied to numerous sectors including Oil & Gas (offshore & subsea), industrial, petrochemical, mining, medical, mobile, nuclear & defence.

Through extensive knowledge, we can design and manufacture pressure vessels to customer and third-party requirements in order to meet the project and application demand.

We have access to an extensive range of metallic, polymeric and elastomeric products in order to manufacture a special pressure vessel that can meet the most difficult of application demands.

Pressure vessels designs would include:
• Threaded Design & Bolted Design Test Vessel
• Mixing Bottle
• Liquid Bottle
• Intensifier
• Closure

Pressure Vessels are manufactured in-house therefore shorter lead times are available

Special & Standard Bladder Accumulators
