CI No. 45 – Steam Line Corrosion Inhibitor

Condensate-Line Corrosion Inhibitor for Steam Distribution and Return Systems

CI No. 45 is the condensate-side protection for steam systems — the treatment that protects everything downstream of the boiler after the steam leaves the vessel. When steam condenses, dissolved carbon dioxide forms carbonic acid in the return side of the system, and that acid quietly pits condensate lines, traps, and return piping until they leak. Boiler-side treatment does not solve that problem. No. 45 does.

Its volatile neutralizing amines travel with the steam through the distribution network and condense alongside it, raising condensate pH where the acid actually forms rather than only where the product is fed. That is what makes it effective: the chemistry goes where the steam goes, and the protection shows up where the metal is under attack.

In practical terms, CI No. 45 helps extend the life of condensate piping, reduce trap and return-line failures, and preserve the energy-recovery value of clean condensate return. In steam programs using CI WT No. 34 on the boiler side, No. 45 is the matching condensate-side treatment — two products covering two different corrosion mechanisms in two different parts of the same system.

CI No. 45 Steam Line Corrosion Inhibitor

Neutralizing amine condensate treatment formulated to protect steam condensate lines and distribution piping from carbonic-acid attack after the steam leaves the boiler. Built for the downstream part of the system that boiler-side treatment products do not reach.

Product Type
Neutralizing Amine Steam Line Corrosion Inhibitor

Technology Base
Volatile Amine Condensate pH Control Chemistry

Primary Function
Neutralize Carbonic Acid Before It Pits Condensate Piping and Traps

Application Role
Condensate-Side Corrosion Protection for Steam Distribution and Return Systems

Performance Focus
Distributed pH Stabilization, Acid Neutralization, and Condensate-Line Protection

Operational Mechanism
Volatile Amines Travel with the Steam and Condense Alongside It, Neutralizing Acid Where It Forms

Process Target
Steam Condensate Lines, Steam Traps, Return Piping, and Distribution Piping

Operational Benefit
Protects the Part of the Steam System Boiler-Side Chemistry Cannot Reach

Use Environment
Steam Boiler Plants, Institutional Heating Systems, Industrial Steam Networks, and Condensate Recovery Systems

Program Fit
Condensate-Side Companion Product to Boiler-Side Steam Treatment Programs

Maintenance Value
Extends the Life of Condensate Piping and Preserves the Energy-Recovery Value of Clean Condensate Return

Control Target
Maintain Condensate pH in the 8.3 to 8.8 Range

Operational Notes
• This is the condensate-side treatment in the line — the product that protects the steam system after the steam leaves the boiler
• Carbonic acid forms when carbon dioxide dissolves into cooled condensate, and that is what quietly pits return lines, traps, and condensate piping until they leak
• Volatile amine chemistry works because it goes where the steam goes, then condenses where the acid forms, instead of staying at the injection point
• This is the product that pairs with No. 34 in steam service — No. 34 handles boiler-side protection, No. 45 handles the condensate side
• Dose at roughly 1:1000 through a proportioning pump or injection into the steam header after the deaerator
• Test condensate pH immediately after sampling — it shifts quickly after exposure to air, so delayed readings mislead operators

Practical Fit
CI No. 45 is the steam-line corrosion inhibitor for operators who already understand that boiler protection alone is not enough. It belongs in steam programs where the real risk is what happens after the steam condenses — the acid forms, the return side starts disappearing from the inside, and the system corrodes out underneath otherwise well-run boiler chemistry.

This block is built directly from the positioning you provided: a neutralizing amine steam-line corrosion inhibitor for steam condensate lines and distribution piping, designed to neutralize carbonic acid by using volatile amines that travel with the steam and condense alongside it. It also preserves the line architecture you established by defining No. 45 as the condensate-side companion to boiler-side steam treatment products, especially No. 34 in steam applications.
