Reinforcing Bar Couplers for Cryogenic Applications

Product catalog summary

Overview: The document discusses Ancon's CTT range of tapered-thread couplers designed for cryogenic applications, specifically for use with cryogenic-grade reinforcing bars in LNG and LPG storage tanks. These couplers are tested at temperatures as low as -168°C/-270°F and comply with EN 14620-3 standards.

System Benefits:

Compliance with EN 14620-3 for structures storing refrigerated liquefied gases.
Tested with cryogenic-grade rebar at both ambient and cryogenic temperatures.
Compact design suitable for confined spaces.
Tapered-thread design for easy alignment and engagement.
Quick and easy installation to accelerate construction speed.

Project Reference: The Yamal LNG project in Russia utilized over 16,000 Ancon tapered thread cryogenic rebar couplers for its storage tanks, demonstrating the product's application in extreme conditions.

Standards and Specifications: Ancon CTT couplers are suitable for structures built according to EN 14620-3:2006, which outlines requirements for concrete components of tanks storing liquefied gases at temperatures between 0°C and -165°C.

Cryogenic-grade Rebar: Krybar® is the rebar used, designed for temperatures down to -170°C/-274°F, and was part of Ancon's testing program.

Product Range:

Standard Cryogenic Couplers (CTTS): Connects two bars of the same diameter where one can be rotated.
Positional Cryogenic Couplers (CTTP): Used where neither bar can be rotated, includes a male section, female section, and locking nut.
Transitional Cryogenic Couplers (CTTT): Joins bars of different diameters where one can be rotated.

Technical Specifications: Detailed specifications are provided for various bar diameters, including external diameter, coupler length, weight, torque requirements, and part numbers for each type of coupler.

Disclaimer: The document notes that construction details should be handled by qualified professionals and that Ancon reserves the right to modify product designs.
