Notched I-Rod™ is available to prevent corrosion on stainless steel tubing
Tight crevices between tubing supports and clamps are another type of crevice corrosion that is difficult to avoid and must be addressed. Notched I-Rod™ has proved to be an excellent solution for preventing pitting and crevice corrosion on offshore stainless steel tubing installations. The I-Rod™ holds the tubing tight while ensuring that no moisture is trapped against the stainless steel surfaces.
