What Does Pulling Head Mean?
A pulling head is a fitting that is attached to the end of a pipe that makes it possible to pull the pipe through a borehole. It is commonly used in small-diameter horizontal directional drilling (HDD) operations for the easy installation of pipe. The process of pulling pipe is essential to many trenchless construction methods.
Trenchlesspedia Explains Pulling Head
Pipe pulling heads are reusable attachments that are fitted to pipes during the installation phase of horizontal directional drilling. Once the pilot hole is excavated and the borehole is reamed to the desired size, then it is time to pull the pipe through the hole. The pipe to be installed is usually held at the exit pit of the operation awaiting the completion of the borehole excavation.
The pulling head may take different forms. One design includes threads on one end for screwing the head to the pipe and a metal ring on the other end. Once securely attached, the drilling operator can hook to the ring and pull the pipe through the hole.
