CCJ^TM

Asahi Kasei's bimetallic transition joint, CCJ^TM, is used to connect aluminum to stainless steel pipe. With its high reliability under the cryogenic condition and leakage resistance, it has been installed in many equipment all over the world.

CCJ^TM is manufactured specifically for connection of dissimilar metals for use in cryogenic or high-vacuum lines, by machining explosion-bonded multi-layered BACLAD^TM plates to the following configuration.

1. Direct welding of stainless and aluminum alloy pipes using CCJ^TM allows no leakage of liquide or gas which assures advantageous environmental safety.
2. Smaller diameter, in comparison with flange connection, enables you to provide compact pipeline design.
3. CCJ^TM is available for any size of pipes less than 76 inches.
4. Bond strength between dissimilar metals is too great and stable to be affected by heat cycle.

CCJ^TM is manufactured to order, in nominal bore sizes from 3/4 to 76 inches.

LPG
Liquid nitrogen
LNG
Others

Note)
If the fluids are either oxygen, liquid oxygen, hydrogen or carbon monoxide,
they may cause the bad reaction, so please consult us.
(CCJ^TM-Ag can be used for those fluids.)

During welding work of stainless steel or aluminum pipe to CCJ^TM, the maximum allowable temperature at the bonded interfaces in CCJ^TM is 350°C× 30min.
