24” Offshore Gas Export Pipeline Riser Repair

Two sections along a 24” nominal bore Gas Export Pipeline Riser on a Philippines offshore gas platform were found experiencing external corrosion under the passive fire protection. All repairs were critical as these risers could not be shut down, and pressures could not be reduced due to their offshore location. With the high design pressure […]

30″ Directionally Drilled Natural Gas Pipeline Coated with Scar-Guard

Directionally drilled natural gas pipelines are often challenged with concerns of coating damage from the abrasion of pull back. Girth welds require a field applied coating where the bond strength is less than that of the factory applied coatings and the raised height of the weld becomes a target for damage. Repairing coating damage is […]

20″ Underground pipeline external corrosion repair

Various 20″ underground pipelines were excavated due to serious external corrosion issues. The lines were found to have wall loss of up to 50% due to localized pitting. See the case study below to learn how NRI’s products were able to permanently repair the pipes before restoring the excavation.

10″ Cooling Water Line MIC Repair with Thermo-Wrap Inspectable

Micro-biologically Influenced Corrosion (MIC) attacked over 2,000 weld locations on thousands of feet of a refinery’s stainless steel cooling water lines. MIC, bacterial induced corrosion, is caused by approximately a dozen known species of bacterial microorganisms. These bacteria thrive in water or soil conditions with a pH of 4 to 9 or temperatures of 50F […]

16″ OD Flare Line Rehabilitation with NRI’s composites

An NDT inspection revealed a high condensation of H2S gas had caused internal corrosion in several places in a petroleum company’s flare line. During the inspection corrosion was located all over the pipe, including complex geometries such as elbows and tees. In some places, the steel was so compromised by the corrosion, that ordinary means […]

48″ Steel Pilings Impact, Abrasion and Corrosion Protection

Traditional coating systems used on steel pilings can get easily damaged due to abrasion and impact action caused by tidal changes and unfavorable weather conditions. Take a look at the case study below to see how NRI’s Syntho-Shield can not only be used as a sacrificial coating to protect lines against external damage, but also […]

Dome Roof Repair with Thermo-Wrap Inspectable Composite

During routine inspection, a Texas chemical company discovered pinhole leaks which required immediate repair due to MEA vapors being released into the atmosphere. The lead time and estimated costs, upwards of $85-95k, to make the repairs through traditional mechanical methods of cutting, welding and coating, steered this company to NRI for a more cost-effective, timely, […]

30″ OD HDD Coating Protection for Pull Back Protection

HDD pipelines are often challenged with coating damage from the abrasion of pull back. Girth welds require a field applied coating where the bond strength is less than that of the factory applied coatings and the raised height of the weld becomes a target for damage. Repairing coating damage is often costly; excavation costs alone […]
