 For forty years, Tube Turns has provided Hinged Closures for a wide range of applications such as Pipeline Scraper Traps, Pig Launchers/Receivers, Filters, Meter Provers and Pressure Vessels.
Tube Turns supplies Threaded closures in popular sizes ranging from 2" through 24" in ANSI class 150 through 900. Threaded closures in 26" through 36" 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 mechanisms on larger sizes. Tube Turns Threaded Closures are manufactured utilizing the precision of CNC machining to provide accurate and consistent dimensions. Safety
Threaded Closures meet ASME Section VIII, Division I requirements. Each Threaded Closure has a pressure-warning device to alert the operator of any internal pressure in the pipe or vessel before opening the head. Also, the O-ring gasket seal is broken before the Hub/Head ACME Threads are completely disengaged which allows pressure to bleed and provides additional warning to the operator of existing internal pressure.
Operational Assurance
To assure that the Threaded Closure will consistently open and close easily, Tube Turns has coated the ACME Threads on the head with a Flouropolymer coating that provides corrosion resistance and solid film lubrication. This is used in combination with liberal grease on the threads to assure reliable closure operation. The Pressure Warning Device is manufactured from Stainless Steel to provide corrosion protection for this safety item.
