I-Rod thermoplastic (white) works extremely well for most process piping conditions. In situations with extreme operating temperatures, Deepwater offers I-Rod HT material (amber) or I-Rod PEEK (tan) material that protects up to 480º F.
Polyshrink is applied over the shank of the U-bolt to protect the pipe's paint during installation. The UV-stable, cross-linked polyolefin material can be used in temperatures up to 230 °F (110 °C).
3. Coated Nuts
The same coatings that are available in the U-Bolt itself are available for the four (4) nuts that are part of each Nu-Bolt assembly. Extra nuts are available separately.
4. Coated U-Bolt
Our carbon-steel Nu-Bolts are available with one of two coatings: Hot-dip galvanized or SermaGard®. SermaGard is a corrosion-resistant coating reliable in even the harshest offshore conditions. Nu-Bolts are also available in 316 SS.
