Unlike other devices, STI Marine Collars are engineered so pads firmly grip the pipe until properly attached and don’t slide down in overhead conditions.
STI versus Others
When pipe vibration occurs, STI’s robust intumescent liner protects pipes from potential damage while other solutions with sharp metal edges make direct contact.
Competitive collars have sharp edges that typically scratch and damage plastic pipes due to excessive vibration. Over time, these conditions can cause excessive pipe damage and potential failures.
