Field engineers can now reference the standard on tablets during a turnaround. If a question arises about the required alkaline solution concentration for a specific vessel, the answer is a search bar away. This immediacy is vital; in a shutdown scenario, delays cost millions of dollars per day, and cutting corners on corrosion prevention can cost lives.

The numbering provides historical context: indicates it was the first standard practice ("SP") published in 1970 ("70"). It was the very first "Standard Practice" released by NACE International (now part of AMPP). nace sp0170 pdf 2021

NACE SP0170, also known as "Control of Stray Current Corrosion," provides guidelines and best practices for the control of stray-current corrosion that can affect pipelines, metallic structures, and other infrastructure. Stray current corrosion is an electrochemical process that can lead to significant damage and leaks in pipelines and similar structures. Field engineers can now reference the standard on

: Using alkaline "soda ash" washes to neutralize any acidic species that form on the metal surface. Dehumidification The numbering provides historical context: indicates it was

Because alkaline solutions can introduce risk of chloride stress corrosion cracking, the standard mandates strict limits on chloride concentrations within the wash water and requires the addition of corrosion inhibitors. 3. Dehumidification / Dry Air (Excluding Liquid Water)
