In the world of industrial corrosion control, few standards carry as much weight as those published by NACE International (now part of AMPP: The Association for Materials Protection and Performance). Among the vast library of best practices, one document consistently emerges as a critical reference for engineers in the oil, gas, chemical, and water treatment industries: .

is highly corrosive and generally avoided, while acid below 90% is severely corrosive to carbon steel. 2. Velocity and Flow Rate Management Among the vast library of best practices, one

Addresses velocity effects, contamination, and moisture absorption (hygroscopic nature). Technical Guidelines for Sulfuric Acid Storage

The RP provides a comprehensive guide for the design, installation, and maintenance of CP systems for steel pipelines. It covers the fundamental principles of cathodic protection, including the electrochemical reactions involved, and provides guidelines for: including the electrochemical reactions involved

Carbon steel tanks require heavy sacrificial corrosion allowances (typically 3.0 mm to 6.0 mm) added directly to the minimum structural wall thickness.

: Must maintain very low fluid velocity (typically below 0.6 to 0.9 m/s or 2 to 3 ft/s ) to prevent the protective sulfate film from eroding.
