Oil-and-gas infrastructure, wellheads, miles of pipeline, tanks, and offshore modules face salt-spray, chemicals, temperature swings, and constant vibration. A pinhole in the coating can snowball into corrosion, leaks, and unplanned shutdowns.

For twenty years NWTI has focused on corrosion management across upstream, midstream, and downstream assets, helping owners stretch service life and cut life-cycle cost. Our job is simple: inspect early, document clearly, and make sure every layer of protection does its job before the asset goes back under pressure.

How we help

We open every engagement with a full coating & steel survey. Certified inspectors verify dry-film thickness, adhesion, and surface condition, then rate corrosion severity using ISO 4628-3 and ASTM D610 standards. The survey gives you a hard-number baseline for maintenance planning.

During construction or turnaround work, our NACE/AMPP team monitors surface prep, ambient conditions, blast profiles, and each pass of the spray gun, creating a photo-rich record that proves compliance and supports warranty claims.

Protection goes beyond paint. AWS-, CWI-, and CPWI-certified welding inspectors cover critical joints and tie-ins, while API inspectors keep pressure vessels and storage tanks inside code limits. If something fails, our failure-analysis team digs into root cause and lays out fixes that stick.

The NWTI edge

We are vendor-neutral. Our only stake is the integrity of your asset. With more than 3,000 inspections completed and a 98% defect-resolution rate, we know the difference between paperwork compliance and real-world performance.

Every project gets daily reports and real-time communication, so decisions happen while crews are still on site, not weeks later. The result is less rework, safer operations, and coatings that last.
