The Hendrix Group has developed several online process and corrosion calculations for the chemical and refining industries. The source material for the calculations is technical literature (API, NACE and others) in the public domain, and full references are provided. A lot of good research has been done over the years. To fully understand the context of diagrams published in standards, we like to dig down to original source material. Some of our sources are hard-to-find historical papers. 

Calculations offer the choice of US customary and metric units. The results of the calculations are illustrated with charts where this is helpful.

The links below provide access to the descriptions of online calculations that will be available free of charge for registered users.
