Nu-Bolt™
Anti-corrosion pipe support assembly for I-beam supports

Below are the basic specifications for the Nu-Bolt Assembly, including the dimensions of the entire assembly (imperial and metric), I-Rod and I-Rod HT specifications, as well as specs for the polyolefin (heat-shrink) used to coat the U-bolt. Deepwater has also begun to offer PEEK material for environments that prove too severe for either (though these instances are rather rare). For information on PEEK, or aspecifications for any other aspect of Deepwater's pipe support systems, please contact us.

Note: The information given herein is believed to be reliable. However, no guarantee or warranty of any kind is implied with respect to accuracy or completeness of these data.
