Cryogenic joints are mainly used for transition connections between stainless steel and aluminium tubes. They are mainly used in the cold box of air separation, as the pipe connection in the cold box is not allowed to leak, so it can not be connected by flanges, but only by welding, and stainless steel and aluminium tubes can not be welded directly, so it is necessary to use steel and aluminium joints for transition.
Phohom's cryogenic transition joint made from explosive welding process owns high sealing and bearing capacity and it plays a key role in the low temperature engineering.We also provide other cryogenic transition joints of aluminum-stainless steel, titanium-stainless steel and other dissimilar metal combinations for you to use in the connection between transmission pipelines and liquefied gas storage tanks, heat transfer equipment and other equipment.
