ASME Quick (Fast) Opening Closures
Insulated Joints (also referred to as “Isolation Joints” or “Insulating Joints”) are available in sizes ranging from 2" thru 48" and pressure ranging from ANSI 150 to ANSI 900.
Tube Turns Monolithic Insulated Joints electrically isolate sections of pipeline to prevent corrosion caused by stray electrical currents or interference from other pipelines and power transmission cables. Three features assure electrical isolation:
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
Pig/Scraper launchers and pig/scraper receivers are installed on pipelines to launch and receive pipeline pigs, pipeline spheres, and pipeline inspection tools. Pig launchers & pig receivers offer a safe and effective means of inserting and removing pipeline pigs to and from pipelines
Connection types including full and reduced access as well as mitred 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.
