A continuous flow of dry nitrogen keeps the space between an insulated pipe and its cladding dry and oxygen-free, so the corrosion hidden under insulation never gets the conditions it needs to start. Patent protected: Norway 347314 · United States 12,638,123 · Australia 2022407959 · Europe EP4445061 [See How It Works](https://www.nitrogas.no/nitrogen-shield#how-it-works) **THE PROBLEM** ## Corrosion under insulation attacks where nobody can see it. Insulated pipework works in some of the harshest environments on Earth. Rain, spray, and humidity find their way through cladding and into insulation, and once water is in, it stays. The steel underneath corrodes out of sight, and the industry's answer has been to strip insulation, inspect, repair, and reinstate, over and over. The scale of the problem is well documented. ![storm-sea](https://www.nitrogas.no/hs-fs/hubfs/storm-sea.jpg?width=1920&height=1080&name=storm-sea.jpg)   --- ## **40-60%** **of pipe maintenance costs** Share of pipe maintenance costs attributed to corrosion under insulation in the oil, gas, and petrochemical industries. [Published review, Metals, 2022](https://www.mdpi.com/2075-4701/12/4/561). --- ## **Hidden** **until the cladding comes off** Corrosion under insulation occurs on insulated carbon and low-alloy steel equipment and is concealed by the insulation system itself. [Metals, 2022](https://www.mdpi.com/2075-4701/12/4/561). --- ## **~50%** **of hydrocarbon leaks** Corrosion under insulation accounts for approximately half of all hydrocarbon leaks in the oil and gas sector, per DNV. [Reported July 2026](https://www.worldpipelines.com/project-news/06072026/industry-collaboration-brings-new-insights-on-cui/). **HOW IT WORKS** ## Corrosion needs oxygen. The system removes it. Steel, water, and oxygen together produce corrosion. Keeping water out of insulation has never worked reliably. Nitrogen Shield Technology works on the other ingredient: it maintains an oxygen-free atmosphere in the annular space between the pipe and its cladding. Fe IRON + O2 OXYGEN, REMOVED + H2O WATER → Stable NO REACTION 01 · MECHANICAL PROTECTION Protect The pipe, its insulation, and the cladding stay exactly as designed. The system works inside the space that already exists between them. 02 · ATMOSPHERIC CONTROL Displace A continuous flow of dry nitrogen creates an oxygen free atmosphere in the annular space and keeps the insulation material dry, carrying moisture out before it can accumulate. 03 · INTEGRATED MONITORING Monitor Sensors track flow, pressure, and integrity in real time, so the condition inside the insulation is measured rather than assumed.

Keeps insulation dry Continuous nitrogen flow helps maintain a dry protective environment inside the insulation system. Reduces corrosion risk A drier, oxygen-reduced atmosphere lowers the conditions that drive corrosion. Extends asset life Reduced degradation helps preserve pipeline integrity and service life. Removes moisture Moisture is transported out of the insulation space before it can accumulate. Maintains performance Stable internal conditions support reliable system operation over time. Measured, not assumed Integrated monitoring means the protective atmosphere is verified continuously, not inspected occasionally. ## Want to know more?
