industrial gas regulations, CGA regulations, beer over foaming, large cryogenic tank, industrial gas deliveries, bad cryogenic hose, how to fix a dewar

The term “ASME Certified” gets thrown around a lot in the cryogenic and compressed gas industry. But what does that really mean and why is it important?

Invented in 1892 by Sir James Dewar, the double-walled cryogenic storage vessel known as a “dewar” revolutionized the cryogenic industry by allowing cryogenic media to be stored for longer periods of time. Though the concept didn’t change much over the years, the biggest innovation came in the form of multilayer insulation, which increased storage times dramatically and made the dewar the industry standard. (Incidentally, it was also discovered that the same construction also kept hot liquids hot, prompting the development of the modern thermos.)

Flow rate and pressure are constant concerns when it comes to cryogenics. When the demand for gas increases higher than the output of the liquid cylinder, both the pressure and flow rate drop in response. Here’s where a vaporizer saves the day.

Ratermann has a long and established relationship with Taylor-Wharton, and is one of the largest North American distributors for all DOT-4L liquid cylinders. Ideal for a wide variety of liquified gases, Taylor-Wharton cylinders lead the industry in quality and safety.

The extremely low temperatures that cryogenic systems operate under causes materials to become brittle and more susceptible to damage. Any foreign particles such as dirt, dust or even water vapor can damage the system by scratching or abrading components. That, in turn, leads to leaks that can release cryogenic fluids and cause life-threatening situations.

Once you’ve identified and installed the best flexible hose for your gas or cryogenic application, you can’t just set it and forget it. Just like the rest of the components of your system, regular inspection and maintenance is important for getting the most longevity out of your system.
