12″ OD x 1.5″ OD Tee Rehabilitation with NRI Composites

A 12″ OD line with a number of dead nozzles was experiencing severe internal wall loss. Since it was a diesel line, with an operating pipe temperature was of 375 F, solutions were limited. Because of the difficult geometry, the end user decided to use NRI’s conformable, cold welding products to repair the line while […]

2″ OD Hydrocarbon Branch Enclosure Encapsulation

Atmospheric corrosion is common among offshore pipes. During a routine inspection, severe atmospheric corrosion was noted on a 2” branch connected to a 10” hydrocarbon / water line. Surface preparation was not possible due to the severe corrosion, so NRI recommended a perimeter seal enclosure to encapsulate the entire branch leg. Read more below to […]
