Stainless steel pressure vessel FAQ

TECHNICALQUESTIONS.

  • What are ST Series stainless steel pressure vessels used for?

    The ST Series pressure vessels are designed for reliable and clean fluid handling in demanding industrial environments. Typical applications include adhesive and sealant dispensing systems, paint, coating and lubrication feed systems, chemical dosing, and laboratory or pilot-scale production systems.

  • What pressure can ST Series pressure vessels withstand?

    ST Series pressure vessels are designed to safely operate at a maximum working pressure of up to 100 psi (6.9 bar). This enables stable and consistent material supply in industrial processes.

  • Should I choose 303, 304 or 316 stainless steel for a pressure vessel?

    All three are corrosion-resistant, and the right one depends on your fluid. 303 machines easily and suits general industrial duty. 304 is the common all-round choice for most dispensing and transfer applications. 316 adds molybdenum for higher resistance to chlorides and aggressive media, which is why it is the usual pick for food, medical, pharmaceutical and marine environments. Send us your fluid and we will confirm the grade.

  • What sizes and configurations are available for the ST Series?

    The vessels are available in capacities from 1 litre to 50 litres — 1, 2, 5, 10, 25 and 50 litres. They can also be flexibly configured with additional ports, air agitators, level sensors and customised fittings depending on your application needs.
