What is a Quick Opening Closure?
Quick Opening Closures | Quick Actuating Closures | Rapid Opening Manways.
Quick Opening Closures are defined as any access into a tank or pressure vessel that is quicker than a blind flange. With different closure designs, each with their pros and cons when it comes to speed of operation, tightness of the seal, and maintenance required.
TUBE TURNS? Products of Sypris Technologies Inc. manufactures a family of closures in sizes ranging from 2” to 72”. Our closures are manufactured from a wide variety of ASME-approved materials including Carbon Steel, Stainless Steel (304, 304L, 316, 316L, Duplex, and Super Duplex), Monel?, Inconel?, Hastelloy?, and other exotic materials as specified by our customers. TUBE TURNS? designs and manufactures a complete line of closures to international standards, including ASME Section VIII Division I and Division II, PD 5500 / BS EN 13445, with termination specifications to meet ASME B31.3, B31.4, B31.8, and many others. All closures can be designed for either horizontal or vertical application and can be equipped with such accessories as sight glasses, nozzles, drains, gauges, sampling ports, open/close automation, and safety interlocks. Connection types including full and reduced access as well as designs for inclined or declined vessels are available. Sypris Technologies, TUBE TURNS? Products offers the most diverse and complete closure product portfolio in the world.?
Quick Opening Closure Applications
Closure Styles
Double Bolt Yoke Style. (Clamp Style)
compact in size and functional in design. A typical unit consists of a forged hub, a hinged blanking head, split-yoke clamps, operating bolts, and a self-energizing O-ring gasket. Materials of construction are in accord with ASME specifications and comply with applicable rules of the applicable ASME code for Pressure Piping and with the ASME Boiler and Pressure Vessel Code.?
Tube Turns Double Yoke Style Closures are widely accepted throughout the world for applications where frequent access is required or where the blind flanges are cumbersome and time-consuming. Yoke Style Closures can be equipped with operating aids to simplify the opening and closing tasks. Devices such as chain and sprocket drives are available to allow a single operator to open in under a minute with no tools in the field. Size range 6” – 72” Pressure range ASME 150 - 2500
Tool-Less Locking Band Style Closures.
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?
Threaded Closures
Simple Yet Robust. Due to the strong and simple design, a threaded closure provides the lowest maintenance of all Quick Opening Closures.
For over forty years,?TUBE TURNS? has provided Closures for a wide range of applications such as Pipeline Scraper Traps, Pig Launchers/Receivers, Filters, Meter Provers and Pressure Vessels.
TUBE TURNS??manufactures Threaded closures in popular sizes ranging from 2" through 24" in ANSI class 150 through 900. Threaded closures in 26" through 42" are available up to ANSI class 600. Threaded closures are available in horizontal and vertical orientations. Threaded closures offer safety with a simple design that consists of only a head, welding hub, pressure warning device, integrated tool to assist in opening and closing the larger size closures and heavy duty hinging hardware with adjustable davit mechanisms on larger sizes.?TUBE TURNS? Threaded Closures are manufactured utilizing the precision of CNC machining to provide accurate and consistent dimensions. ?Best used for: pig traps, filters, strainers, scrubbers, heat exchangers, blowdowns, and other vessels?
T-Bolt (Swing Bolt) Style Manways
The T-Bolt Closure is A Compact Closure Design For Tanks, Pressure Vessels, and Filters. Any Vessel or piping system requiring frequent and or quick access.
The simplicity of construction and operation are keynotes of the Tube Turns T-Bolt Hinged Closure. The closure consists of a thick semi-elliptical head that is hinged to a matching hub, a self-energized O-ring, and a suitable number of T-Bolts to effect and maintain a tight seal. For most services, the standard materials—carbon steel and a “Buna-N” 0-ring are satisfactory. Other metals and elastomers are furnished on special request. The T-Bolt Hinged Closure is opened quickly and easily. The operator merely loosens the T-Bolts until they clear the head lugs and allow the head to be swung open on its hinge. Complete, unrestricted access is provided, too, since the standard hinging permits a full 180°opening. ?Quick Opening Swing Bolt Hinged Closure provides a fast, economical, yet simple means of access to pressure vessels and lines that require frequent opening. high-pressure manway
Hinged Closure Materials:
Internal (Wetted) Materials:
Carbon Steel (ex. SA516-70), Stainless Steel (ex. SA240-304, 304L, 316, 316L), Duplex Stainless Steel (ex. SA240-S31803), Inconel (ex. SB168-N0660), etc.

Pressure Warning Devices. Safe, quick, and reliable access.
Our Pressure Warning Device assures both pressure warning and mechanical locking of the closure prior to the 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. Our closure safety systems meet the requirements of UG-35 for quick-opening closures.?
AUTOMATED YOKE STYLE CLOSURES
ASME Self-Opening Opening Pipeline Closures, Process Piping Closures, ASME Pressure Vessel Closures
Tube Turns Automated Closures have flexibility of design and can be developed and manufactured to meet your needs. Our Automated Closures are located in industries throughout the world. Applications for Tube Turns Automated Closures include Pipeline Launchers and Receivers and operations with batch processes such as pulp and paper mills, food process, chemical plants, and petrochemical plants.?
Electric Operated Automated Closures are supplied with electric motors and appropriate gear boxes to drive the yoke bolts and to open and close the head. Electric circuits are wired to a central junction box and a push button control panel is included. A wiring diagram is provided for onsite wiring between the junction box and control panel to complete the installation.?
Pneumatic Operated Automated Closures are supplied with air-driven motors, a gearbox to drive the yoke bolts through a joint chain drive, and a gearbox to open and close the head. Shop air from 60 psi to 90 psi is used for the operation of the unit through a control panel provided with lever-actuated control valves.?
Hydraulic Operated Automated Closures are similar to those described above except that hydraulic motors are used for the driving force. A hydraulic pump system with electric controls can be provided by the units or by the end user.?
