Bolted closures are the most popular closure design specified in high pressure testing vessels. They are a more traditional method, compared to the quick-access range of closure types available but are still a good choice, as they are relatively low cost.
They are easy to handle, simple to operate and their minimal design provides great flexibility; allowing the customer to configure the equipment to their individual project needs.
Various types of seal solutions can be fitted, to suit the application requirements. These include low-cost standard rubber O rings; more complex bespoke engineered plastic seals and even metal to metal type sealing solutions (such as BX rings or C-rings.)
KW Designed Solutions bolted closure pressure vessels are supplied with operating pressures of up to 2069 bar and temperatures ranging from -196°C to +650°C.
