The I-Rod Clip attaches to new or existing saddle-clamp-style supports, eliminating crevice corrosion.
The I-Rod Clip (also called I-Clip) is an individual pipe support installed on the inside diameter of a pipe saddle. The clips are mechanically held in place by the weight of the pipe and an adhesive strip, and can be retrofitted easily on existing pipe runs. New Grinnell and cradle-style supports are easily fitted with I-Rod Clips, and many pipe-support manufacturers have begun to offer them pre-installed in each new support.
Correcting a very old problem – Neoprene pads and other rubber interfaces traditionally used in these applications have proven disastrous by actually promoting the crevice corrosion they were designed to prevent. Pipe-support designers originally believed that metal-to-metal contact was the source of most pipe-support corrosion, but this is not true. The problem is the crevice, which traps water and holds it in contact with the pipe. Pads made of rubber or fiberglass are easily penetrated, and once water is inside, the moisture is held tight against the pipe by the pad. I-Rod Clip eliminates the crevice, so water simply evaporates. It also eliminates metal-to-metal contact, which accelerates corrosion when wet.
Made from the right material – The clips are offered in a variety of materials to match the requirements of different applicatiosn. Standard I-Rod clips are made from I-Rod thermoplastic, the same high-impact material found on all I-Rod brand pipe supports. For extreme temperatures, we offer I-Rod HT material and for large weight loads there are several grades of PEEK. Applications include pipe-cradle retrofits, large-diameter band clamps, high-load riser clamps and concrete or timber pier supports.
