ASME "Quick Opening Closures" Pipeline Closures
For Launcher Receivers, Filter Separators, and other Pressure Vessel Applications. Safe, quick, and reliable access to pipelines. ASME VIII Div 1 compliant
Process industry piping engineers and equipment designers, in response to safety concerns and the need to increase productivity and reduce downtime, are revising their specifications to require extremely quick opening type closures that do not require tools. Anticipating this trend, Tube Turns’ TOOL-LESS® closure was introduced in 2008, with great success. Applications include scraper traps, filters, strainers, separators/coalescers, terminal manifolds, meter provers, distillation towers, storage tanks or any pressure vessel requiring frequent access.
The TOOL-LESS® closure satisfies the design requirements of 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 gauge 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. TOOL-LESS® closures are available in Carbon Steel, Stainless Steel, and other alloys, along with a choice of elastomer lip seal materials to meet the user’s temperature and process compatibility requirements. quick opening closures is customizable to specific design codes, pressure ratings, material requirements, and installation conditions. Best used for: pig traps, filters, strainers, scrubbers, heat exchangers, blowdowns, and other vessels
Fast, Easy Operation Compared to Threaded Closures
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, and as the name implies, without special tools. Complete installation, operating and maintenance instructions are furnished with each TOOL-LESS® closure.
Safe, quick, and reliable access to pipelines
Our Pressure Warning Device assures both pressure warning and mechanical locking of the closure prior to commencement of operation. The Pressure Warning System alerts the operator to any residual pressure inside the vessel should the operator inadvertently attempt to open the closure before all pressure has been relieved. The TOOL-LESS® closure safety system meets the requirements of UG-35 for quick-opening closures.
ASME Pipeline Quick Opening Closure Applications
Quick Opening Closure Vessel Configurations
Tool-Less Closures are available in horizontal and vertical configurations. Horizontal closures are available in left (standard) or right hand hinging and include a robust double pivot adjustable hinge. Vertical closures can be offered with a davit or lifting lug depending on customer preference. Best used for: pig traps, filters, strainers, scrubbers, heat exchangers, blowdowns, and other vessels
Quick Opening Closure Tool-Less Lip Seal Design
Designed for long life, each Tool-Less Closures is furnished with a fully molded self energized lip seal with an integral stainless steel backing ring. Standard lip seal material is Buna-N (-20F to 250F); optional seal materials include FKM Viton, HNBR, Ethylene Propylene, and Explosive Decompression Resistant FKM.
Safe, quick, and reliable access to pipelines
ASME Pipeline Code Stamped Closures
Code Stamping of Tube Turns Closures is available on request at a nominal fee. This includes the furnishing of Partial Data Reports (Form U-2A) verifying shop inspection by a authorized inspector of the National Board of Boiler and Pressure Vessel Inspectors and the Affixing of the ASME Stamp.
Low Maintenance
Designed to be durable and to minimize spare parts. Lip Seals and Other spare parts are in stock when replacement is needed. Quick opening closure is customizable to specific design codes, pressure ratings, material requirements, and installation conditions.
Tool-Less Materials Of Construction
We maintain an inventory of ASME compliant components in carbon and stainless steel including low temperature and high yield materials to accommodate quick delivery. Materials conforming to the latest NACE requirement standard MR0175/ISO 15156, duplex stainless steel, and other specialty alloys are available upon request.
Strict Limits on %CE
Standard hub material is SA350LF2 CL2 combined with SA694F46 (higher yields available). The MTR provided with every closure will list the chemical properties including the &CE to provide a good quality weld (typically .45%)
Now Offering Pipeline Pig Signalers
The Sypris® Technologies Sig-Tech® intrusive Pig Signaler can be installed at pre-determined intervals on pipelines to detect the passage of a cast polyurethane pigs or spherical type pigs.
