Frequently asked questions
Five questions we are asked most often about the HPSTART25.4x4. Every figure quoted here is the as-tested factory specification and is consistent across the entire site.
What are the maximum working pressure and maximum temperature of the equipment?
Maximum working pressure 1000MPa, maximum operating temperature 1200℃, with our self-developed cold-seal integrated high-pressure high-temperature control system. All figures are as-tested factory values, ready for research proposals and tender technical responses.

Does the HPSTART25.4x4 support hydrogen production simulation via water-rock reaction?
Yes. The sealed 300MPa / ±0.1℃ platform is used for sealed rock-fluid hydrogen generation experiments. Select the chamber material according to the fluid chemistry involved, and contact us with your fluid composition for a recommendation.

Does temperature and pressure drift during long experiments?
Over a verified 72-hour pressure-hold and soak run, drift remains negligible and steady-state pressure fluctuation stays within ±1MPa. The integrated control system acquires and adjusts both values in real time under closed-loop control.

What materials are available for the HPSTART25.4x4 sample chamber?
TC4 titanium alloy, 316L stainless steel and alumina ceramic as standard. TC4 offers low density and good strength; 316L is cost-effective for aqueous systems; alumina is chemically inert for corrosive fluids. Custom alloys can be evaluated.

A note on the answers above
All figures are as-tested factory specifications, not nominal values, and are stated identically across every page of this site. Where a figure differs from a brochure or listing you have seen elsewhere, this page takes precedence. For anything not covered here, call 400-184-9193 and ask for an engineer.
