MAKE YOUR OLD TANKS LOOK LIKE NEW
Sometimes your old tanks just need a little TLC to look and work their best again. That’s why we offer a wide range of cryogenic rehabilitation services to our customers. The Allcryo facility in Montgomery, TX, is capable of both a U Stamp and R Stamp, so we are well-versed in the proper procedures, standards, and practices for on all types of cryogenic tanks.
Before
After
Our cryogenic rehab process:
- First, the tank is stripped of all external piping before being sandblasted and primed.
- Vacuum integrity is checked for both inner and outer vessels. We make sure to check
the vacuum on a warm tank and when the tank is cooled with liquid nitrogen. - Vacuum leaks are isolated and repaired using helium and a mass spectrometer.
- Insulation (Perlite) is added to annular space as necessary.
- The vacuum valve, Hoke valve, thermocouple tube, and O-ring are all replaced with new components.
- We then install all new polished stainless steel piping, safeties, pressure building coil,
regulators, and gauges. - Finally, the finished tank is painted using a 2-part polyurethane coating and
pressure-tested for proper operation with liquid nitrogen before shipping.
We can take care of all your cryogenic rehab needs.
