CASE STUDIES
THINKING OUTSIDE THE BOX
— NITROGEN FREEZING SHAFT
Our customer had a large rotary valve. The shaft had broken where it had been welded onto the vanes. The most likely cause of failure was weld stress on the shaft at the point it had been welded to the vanes. Simply cutting out the old shaft and welding a new one was not a viable option.
Our workshop took the complete vane assembly out of the valve and bored a new cavity for a replacement shaft. The new shaft was made fractionally oversized then frozen in liquid nitrogen to reduce its diameter. Once below the size of the machined cavity it was slid into place.
As the shaft returned to normal temperature it expanded and “self locked” into place. The resulting solution provided the customer with a complete and secure shaft replacement without welding.
