Corrosion Allowance

The latest version of IIAR 2, Standard for Safe Design of Closed-Circuit Ammonia Refrigeration Systems will soon be published as “IIAR 2-2014, with Addendum A”. Among other important changes to the standard, there will no longer be a requirement for an additional 1/16” corrosion allowance (CA) on ammonia refrigeration vessels. The design of pressure vessels results in a calculation for the minimum thickness (Tmin) at various places on a vessel (e.g., shell, seams, heads, and nozzels).

Green New Deal and Climate Policy

Climate policy is taking center stage with Democrats in Congress who gained control of the House of Representatives after the 2018 elections and the over 20 candidates vying for the Democratic presidential nomination in 2020. The debate, and rhetoric, is heating up and looks to continue as we head into the presidential election next year.

Avoiding Brittle Fracture When Repressurizing Carbon Steel CO2 Vessels That Have Lost Pressure

A vessel containing liquid CO2 may form dry ice and be at a temperature below -100°F (-73.3°C) if a leak or control malfunction causes its pressure to drop to atmospheric pressure. If the upset condition is corrected and the vessel is repressurized too quickly with warm high-pressure CO2 , there is a possibility of brittle fracture if the vessel material of construction is carbon steel. The industrial gas industry has developed safe and acceptable methods of repressurizing carbon steel CO2 vessels that have lost pressure. These are described in the Compressed Gas Association guideline CGA-6.7.
