The KW Designed Solutions segmented clamp closure pressure vessel, has a quick-acting closure mechanism, which incorporates a 2 or 3-piece clamp arrangement. The segmented clamp closure is innovatively engineered; lightweight yet robust and provides the operator with a quick and simple opening / closing functionality.

The segmented clamp closure is engineered, so that the vessel body remains slender and the closure plug relatively lightweight. A compact flange profile is machined into both the pressure vessel body and the closure plug; ensuring smooth engagement of the segmented clamps and effective containment of the end loads caused by high pressure.

We can also incorporate pressure vessel support frames and closure support frames into the design, to ensure closure alignment to the vessel body is maintained. For larger pressure vessels, automated closure mechanisms can be supplied to aid and simplify the handling of the segmented clamps and closure plugs whilst also optimising vessel access.

KW Designed Solutions segmented clamp closure pressure vessels are supplied with operating pressure of up to 2000 bar and a temperature range of -20°C to +300°C.
