Trinity Products’ Weldless Interlock System - I-75 Inlay Project - MDOT
TRINITY PRODUCTS, LLC TRINITYPRODUCTS.COM 800.456.7473 Trinity Products’ Weldless Interlock System RESULTS: Using Trinity Tri-Loc Casing pipe allowed the contractor to install more pipe per day than traditional welding. Jacking forces of 500,000 pounds were applied to the Tri-Loc joint with no deformation. Despite soft clay in some spots, all joints were fully engaged. In the end, utilizing Trinity Products' Tri-Loc joint gave Lowe Construction the results they were looking for, both installations were completed ahead of schedule, and below cost.
