and more piping engineers and equipment designers in the oil and gas industry are specifying extremely quick
opening type closures that do not require tools. Applications include scraper traps, filters, strainers, separators/coalescers,
terminal manifolds, meter provers, distillation towers, storage tanks or any pressure vessel requiring frequent
access. We are now pleased to introduce our newest closure product line, the Tool-less® closure.
The Tool-less® closure satisfies design requirements in ASME B31.3, B31.4, B31.8, and Section VIII, Div.
1. The entire design has been verified through proven stress calculations, the latest finite element analysis
software, and strain gage testing, establishing a high level of confidence in the structural integrity of the
Tool-less® closure. In addition, fatigue analysis based on severe field condition data has been successfully
conducted on all closure sizes and classes.
FAST, EASY OPERATION
Tool-less® operation is smooth and direct and even the largest unit can be opened or closed in a matter of
seconds by one person. Complete installation, operating and maintenance instructions are furnished with each
Our Pressure Warning Device (PWD) assures both pressure warning and mechanical locking of the closure prior
to commencement of operation. Additionally, the PWD serves the purpose of alerting the operator to any residual
pressure inside the vessel should the operator inadvertently attempt to open the closure before all pressure
has been relieved. Tool-less® closure safety system meets the requirements of UG-35.
Tool-less® closure is available in horizontal and vertical configurations. Horizontal closures include a robust
double pivot adjustable hinge. Vertical closures can be offered with a davit or lifting lugs depending on closure
size and customer preference.
