Ferrous fittings, including steel and cast iron components, are commonly used to connect piping and appliances in water, gas, and fire protection systems. These fittings are selected for their strength and durability, but when a failure occurs, the cause is not always immediately clear. Installation practices, material compatibility, and environmental exposure all play a role in how these components perform over time.
In this episode of Evidence to Answers, forensic engineer Ben explains how ferrous fittings are typically installed and where they are most commonly used. He covers the importance of proper tightening of threaded connections, the role of sealants, and the risks associated with combining dissimilar materials. He also reviews the most common failure patterns seen in practice, including corrosion, improper installation, material defects, and environmental degradation such as soil-driven corrosion and stray current effects.
This video is for those involved in losses and claims where ferrous fittings are a factor. Documenting part numbers, installation details, piping orientation, and maintenance history before removal provides the context needed for a complete and defensible evaluation.
