Our pinned closure pressure vessels are predominantly used for production or research and development applications. The closure provides quick opening and closing of the pressure vessel and high cyclic duty, with a minimal number of components.

By taking the pin out, the closure plug can quickly and easily be removed. We can also automate this closing process if required; with the pin requiring full engagement to activate the safety system before any test can begin.

Our pinned closure pressure vessels are slender in design and when used vertically, have a narrow footprint and require minimal shop floor space.

Applications and Customer Uses

The KW Designed Solutions pinned closure pressure vessel has proven invaluable for clients in the scientific and materials research sector. Working closely with our customer’s specific requirements, this closure design has been developed creating a pressure vessel that uses two closure pins. These must be fully engaged into the incorporated safety system before any test can begin.

An activating shot bolt secures the vessel in position, whilst the operator sets up the components for testing. The equipment has been designed to perform tensile and compressive tests on test specimens (under hydrogen gas pressure) for the automotive industries. Using two pins allows space for the single and centrally positioned mechanical pull rod and the fluid and electrical feed through penetrations.
