The Ancon CTT range of tapered-thread couplers has been designed for use where cryogenic-grade reinforcing bar is being used. Typical construction projects include liquefied natural gas (LNG) and liquefied petroleum gas (LPG) storage tanks to EN 14620-3.
System Benefits
Suitable for use in structures built in accordance with EN 14620-3
Independently tested with cryogenic grade rebar at ambient and cryogenic (-168°C/-270°F) temperatures
Compact coupler design, suitable for confined locations
Tapered-thread design simplifies bar alignment and engagement without cross-threading
Installed quickly and easily, accelerating build speed
Structures to EN 14620-3
Ancon CTT couplers are suitable for use in structures built in accordance with EN 14620-3:2006. This Standard specifies the general requirements for materials, design and construction of all concrete components of site-built, vertical, cylindrical, flat-bottomed steel tanks for the storage of refrigerated, liquefied gases with operating temperatures between 0°C and –165°C. BS EN 14620-3: 2006 supersedes BS 7777-3: 1993.
Cryogenic-grade Rebar
Krybar® is a specially-designed concrete reinforcing steel for cryogenic applications from ArcelorMittal. ‘KRYBAR -165’ is suitable for use in storage tanks with temperatures down to -170°C/-274°F and was the cryogenic-grade rebar used in the test programme undertaken by Ancon.
