Petrochemical complexes, with cracking furnaces, distillation towers, labyrinths of stainless pipe, face a harsher mix of heat, pressure, and chemistry than almost any other sector. A pinhole in a fluoropolymer lining can vent acid; an under-insulation blister can turn into stress-corrosion cracking overnight. Unplanned shutdowns ripple through supply chains and draw instant regulatory scrutiny. For two decades NWTI has kept those problems small, applying the same corrosion-management playbook we refined across industrial and petrochemical plants worldwide. Our rule is simple: find degradation early, document it clearly, and make sure every protective layer performs before the asset returns to service.

How we help

We start with a coating & steel survey. AMPP-certified inspectors record dry-film thickness, adhesion, and rust grades, rating corrosion severity with ISO 4628-3 and ASTM D610 so you have hard numbers for maintenance planning.

During construction or turnarounds, our NACE team tracks surface prep and coating application, photographing every stage and verifying DFT per SSPC-PA 2. The result is a photo-rich record that closes warranty gaps.

Protection goes beyond paint. Welding inspectors with AWS-CWI and CPWI credentials cover critical process welds and tie-ins, ensuring procedures and profiles meet code before hydrotest or startupWelding inspection. API-510/570/653 inspectors certify vessels, piping, and tank farms to the standards petrochemical maintenance programs rely on. And when something fails, our failure-analysis team traces root cause (surface prep, chemistry, design) so it never happens twice.

Every engagement is backed by daily status reports and real-time communication, keeping projects on schedule and surprises off the punch list.

The NWTI edge

We do not sell coatings; we sell insight. Our reporting is vendor-neutral and tied to recognized standards, not opinionNWTI Home. With more than 3 000 inspections completed and a 98 % defect-resolution rateNWTI Home, we know the difference between paperwork compliance and field performance. Decisions happen while crews are still on site, which means less rework, safer operations, and coatings that last.
