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 […]

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 […]

Repair of a 10″ Kerosene pipe with severe internal corrosion

A Kerosene pipe in a US Gulf Coast refinery was experiencing aggravated internal corrosion. Most standard repairs couldn’t handle the high temperature of 255F (124C), and shutting the pipe down would mean hundreds of thousands in lost revenue. One NRI product was able to solve the problem with ease, and in no time! Take a […]

20″ Monoblock Rehabilitation in Mexico

Flanges and mono-blocks are extremely difficult to repair, especially if there is a live leak. The geometry of the monoblock is a limiting factor in the application of most repair methods. The client decided to use NRI’s composite repair solutions in order to mold the repair around the 90 degree angles of the pipe. Read […]
