What QHP does

QHP (Quality Hydraulic Power Limited) is a UK-headquartered specialist manufacturer of hydraulic accumulators and subsea compensators serving the global Oil and Gas industry. Founded in 1987 and based in Chester, the company designs and produces bladder, piston, and diaphragm accumulators, with fabricated stainless-steel variants (316 SS, Duplex, Super Duplex, 6Mo) rated up to 690 bar and qualified for 30-year subsea service life, alongside complementary accessories (mounting elements, safety blocks, nitrogen charging kits, coolers). Manufacturing is fully vertically integrated in-house, including ISO 3834-2 certified welding with 100% X-ray and dye penetrant inspection, seven Doosan CNC machining centres, eight pressure testing rigs up to 50,000 Psi (3,448 bar), dedicated flushing rigs with laser particle counters, a qualification chamber spanning -40°C to +200°C and up to 2,000 bar, and a NORSOK M501-approved painting facility.

The company operates a bespoke, quote-based commercial model with a dedicated in-house sales function and multi-year contracts, shipping over 70% of output from its UK site to a global customer base that includes essentially all major Subsea Tree, Control Systems, Manifold, Fluid Control, and HPU/WOCS providers, plus major Middle East OEMs. Customer segments are concentrated across Subsea Production Systems, Mechanical Seal Systems, Topside Control Systems and Process Packages, and Middle East Oil and Gas, with ancillary non-O&G bespoke work. QHP has been a wholly-owned subsidiary of the HYDAC Group since 2008 and reports nearly 400% business growth since that point, supported by an in-house workforce of approximately 100 employees, sustained capex of about £1 million per annum, and a debt-free balance sheet.

Core offering

QHP manufactures hydraulic accumulators (bladder, piston, and diaphragm types) and subsea compensators primarily for the Oil and Gas industry. The company produces both standard and fabricated accumulator ranges alongside accessories such as mounting elements, safety blocks, coolers, and charging/testing kits, all built to DNV and ASME certification standards.

Product overview

QHP (Quality Hydraulic Power) is a manufacturer of hydraulic accumulators and compensators for the Oil and Gas industry. The company offers a comprehensive portfolio of products centered around three main accumulator types: Bladder Accumulators (Standard and Fabricated Stainless-Steel variants from 1-57 litres, up to 690 bar), Piston Accumulators (0.5-500 litres, up to 2500 bar), and Diaphragm Accumulators (0.16-4.0 litres, up to 210 bar). QHP also manufactures Subsea Compensators qualified for 30-year subsea life. Supporting the core accumulator products, QHP provides complementary accessories including mounting elements (brackets and clamps), safety blocks for accumulator shut-off and discharge, nitrogen charging and testing kits, and coolers (return line, offline, and plate heat exchangers) for thermal management. The products are available with various international certifications and approvals including PED, ASME, DNV, ABS, and ATEX.
