API TR 655 is a technical reference for Vapor Corrosion Inhibitors for Storage Tanks, giving engineers and technical reviewers a focused source for understanding how these products relate to tank corrosion management. As an API Technical Report, it is best suited to background evaluation and informed decision-making rather than prescriptive requirements. For buyers assessing storage tank protection strategies, API TR 655 helps frame the technical considerations around vapor-phase corrosion inhibition and its role in asset protection, reliability, and maintenance planning.

Purpose of API TR 655

The purpose of API TR 655 is to provide technical background on vapor corrosion inhibitors as they apply to storage tanks. It serves as a specialist reference for teams that need context when comparing corrosion-control approaches, reviewing product suitability, or supporting internal engineering studies. Because it is a technical report, it is typically used to inform analysis and interpretation, helping professionals understand the role these inhibitors may play in protecting tank systems under practical operating conditions.

How API TR 655 may be used

API TR 655 may be used by engineering, integrity, reliability, inspection, and maintenance teams involved with storage tanks in oil and gas, refining, terminal, or process facility environments. It can support technical reviews, procurement evaluation, and project planning where vapor corrosion inhibitors are being considered for tank protection. The document is also useful for QA/QC and technical documentation groups that need a consistent reference when comparing approaches, reviewing supplier information, or aligning internal practices with recognized API guidance.

Why API TR 655 matters

API TR 655 matters because storage tank corrosion decisions often depend on practical technical context, not just product claims. This report can help teams evaluate whether vapor corrosion inhibitors are relevant to a specific tank application, support clearer procurement and specification discussions, and improve consistency in engineering review. For organizations focused on reliability and risk reduction, it provides a credible API reference that can support maintenance planning, asset integrity work, and more informed operational choices.
