Way Ahead In Corrosion Control

I-Rod® lab test

Load vs Crosshead Extension test confirms I-Rod's compressive strength

The procedure

The I-Rod® pieces were subjected to compressive loading with a fixture which simulated a 12 inch OD pipeline. Loading was applied, as shown in Figure No. 1, and crosshead extension was measured at 500 lb intervals. The I-Rods were tested in sets of one, two, and three, and a 100 lb pre-load was applied to each test array prior to any measurements. Multiple rods were tested with an 8 inch center to center width on the exterior rods.
