Cryogenic Rebar Splicing Systems

Cryogenic rebar splicing systems are an extension to the LENTON® line of concrete reinforcement products available from ERICO®. Our products provide the ideal splicing solution for joining rebar in cryogenic construction applications. By combining the LENTON taper-threaded couplers with state-of-the-art materials, we have developed one of the slimmest couplers on the market, while still maintaining top performance.

LENTON brand of cryogenic rebar splicing systems should be specified whenever cryogenic-grade rebar is used or when during normal operating or emergency conditions the temperature falls below -20° C (-4° F). Typical construction projects include LNG and LPG storage tanks.

Features

Designed for use in structures built in accordance with BS 7777 Part 3 and EN 14620-3
Utilizes the time-tested, field-proven LENTON taper thread
Taper thread eliminates crossthreading
Easy to install
Slim coupler design reduces need for concrete cover
Reduces rebar congestion

Benefits:

Improved performance and reliability at cryogenic temperatures (-165° C / -265° F)
Available for a wide range of applications
Small coupler diameter helps minimize cover and helps eliminate congestion
Unique taper thread requires no lock nuts and provides a positive locking, no-slip connection
Requires no special skill and reduces labor costs

Performance:

At ambient temperatures, the cryogenic couplers are intended for use in reinforced concrete structures designed and built in accordance with major international building codes, such as ACI® 318 Types 1 & 2, DIN 1045 and BS8110. At cryogenic temperatures, the tensile strength of the splice meets or exceeds the yield strength of an unnotched bar. This is known as the Notch Sensitivity Ratio (NSR).*

NSR= Tensile strength for LENTON brand of cryogenic splice > 1
Lower yield strength of unnotched bar

Uniform elongation at maximum load on cryogenic spliced bars is a minimum of 1%.

_{*Note: In the absence of any current codes governing the use of splicing systems for cryogenic applications, we have applied the reinforcing bar test criteria utilized in BS 7777 Part 3 and EN 14620-3. Construction codes BS 7777 Part 3 and EN 14620-3 are the most often applied standards for the design and construction of flat-bottomed, vertical, cylindrical storage tanks for low-temperature service.}

Applications

Cryogenic rebar splicing systems provide the ideal splicing solution for joining rebar in extreme low temperatures and cryogenic construction applications.

A12
LENTON® standard couplers are designed to splice the same diameter bars where one bar can be rotated and the bar is not restricted in its axial direction.

P14
The P14 style couplers are designed to splice two curved, bent or straight bars when neither bar can be rotated and where the on-going bar is free to move in its axial direction. Typical applications for these couplers are for the splicing of pile cages. The P14 position coupler can be separated in two pieces for application against form work.
