42" pre-stressed concrete pipe (PCCP) composite repair

NRI’s composites are not limited to metallic pipes. The city of Orlando in Florida had issues with a leaking 42″ pre-stressed concrete pipe (PCCP). Since this was a force main line, it couldn’t be shut down, and the alternative to cut-and-replace was out of the question. Read more below to learn why the best solution […]

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 […]

NRI's composites save European underground water lines

During the winter months, district heating systems distribute hot water 266°F (130°C), from European Union power plants to residences and returns cool water 140°F (60° C) to the plants. When the snow melts in spring, these underground the bunkers that hold the pipes are often full of standing water which causes a high level of external corrosion. Read […]

60" OD Water Pipeline Repair in Saudi Arabia

Composite repairs have many uses, and although the most common repairs are in the oil and gas industry, this week we are taken to Saudi Arabia where a water line was experiencing external corrosion with over 60% wall loss. In order for the system to stay online, an immediate repair was necessary. NRI calculated that the […]
