Pull Back Assist
Your Need
Installing product pipe in ground conditions susceptible to hydrolock.
Our Solution
Our pull back assist can free up hydrolocked or stuck pipe. During pull back, we attach a rammer to the product pipe and hammer impact force helps free up hydrolocked or stuck pipe. This technique has been successfully used on steel pipe and HDPE.
What is hydrolock?
Hydrolock is a when the external pressure on the product pipe—from ground water pressure, drilling fluid pressure and/or soil conditions—exceeds the drill rig's pull back capability or the product pipe's tensile strength. It is common when drilling underwater or in loose soil conditions.
