Our bolted closure pressure vessel is a popular choice with customers who work within the scientific, materials testing and research industry.

To provide the confidence that the vessel will remain pressurised, for the entire duration of demanding testing applications; we utilise torqued up bolts and clamp the closure seal.

The bolted closure is typically associated with reactor pressure vessels and autoclaves; providing a robust sealing solution. This gives the customer the ability to conduct high elevated temperature testing, for durations of up to and over 3 months, where immediate access to the vessel is not required.
