AMPP TR21544-2022, Corrosion and Mitigation Techniques for Fire Protection Piping Systems

Product Number: AMPP TR21544-2022

Publication Date: 2022

$109.00

This report explains different types of corrosion phenomena and contributing factors of corrosion that can occur in fire protection systems (FPS), such as water corrosivity, MIC, trapped air (wet systems), residual water (dry systems), and pipe weld corrosion. The basis for selection of corrosion mitigation strategies for corrosion mitigation and management of FPS are also discussed.

Corrosion that results in pipe leakage or obstruction is the most significant issue for owners of water-based FPS or fire sprinkler systems, in terms of both cost and system reliability. Corrosion damage/products and mineral deposits can impair the effectiveness of sprinkler systems, leaving facilities vulnerable to uncontrolled fire loss even though they are equipped with fire protection systems. This report describes practices that have been successful in mitigating FPS corrosion.

Evaluation of Microbial Corrosion Implications in Flooded Pipe Strings

Product Number: MECC23-20068-SG

Author: Razan Alharthi; Matteo Leoni; Amani Alghamdi; Xiangyang Zhu

Publication Date: 2023

$20.00

In the construction of a 400 km gas pipeline system, thirty (30) pipe strings (approximately 26 km) were exposed to atmospheric conditions and rain flooded for 1-2 years. The pipe is 56”, uncoated carbon steel. Prior to their application in gas pipeline construction, the inspection detected uniform internal corrosion in some strings, but no signs of pitting corrosion were observed.
