Nu-Bolts / I-Rod
|
Nu-Bolt assemblies have been in service for over 20 years without a single reported failure. Designed by corrosion engineers, the Nu-Bolt assembly combines the half-round I-Rod support with a modified pipe U-Bolt. A variety of corrosion-resistant treatments provide reliable, long term service in the harsh operating environments associated with offshore oil and gas production and coastal process facilities. Polyshrink is applied over the shank of the Nu-Bolts to protect the paint system during installation. Polyshrink is not designed to protect the Nu-Bolt. The material is a cross linked, high compressive strength, UV stable polyolefin, which can remain in service in temperatures up to 230 °F (110 °C). Coatings – The carbon steel Nu-Bolt is available with one of two coatings. Hot-dip galvanizing or SermaGard®. SermaGard is a corrosion resistant coating reliable in even the harshest offshore conditions. Nu-Bolt is also available in 316 S/S. Half-round I-Rod support – The standard I-Rod material works extremely well for most process piping conditions. In situations with extreme operating temperatures, Deepwater can substitute the more resistant I-Rod HT material. Deepwater has also begun to offer PEEK Material for environments that prove too severe for either (through these instances are rather rare). For details about all three materials, see the Nu-Bolt specifications page.

Nu-Bolt installed on a vertical pipe. The first platform to spec Nu-Bolts for a new build was in 1989. |
