Abstract

A pullhead includes a housing that has a first end and a second end. The housing is separable between a first body and a second body. The first and second bodies are pivotally coupled at a joint and the first and second bodies together define an interior pocket of the housing. The interior pocket has an interior pocket width. The pullhead head includes a pulling feature at the first end. The interior pocket includes an interior retainer flange that has an inner width and is disposed within the interior pocket. The inner width is less than the interior pocket width. The first body and second body are pivotable relative to each other around an axis at the joint that is transverse to a pulling direction.

IPC Classes  ?

• F16L 1/032 - Laying or reclaiming pipes on land, e.g. above the ground in the ground the pipes being continuous
• F16L 1/06 - Accessories therefor, e.g. anchors
• E21B 7/00 - Special methods or apparatus for drilling

Abstract

A pipe pulling technique where an adaptor is attached to the end of the pipe prior to the pipe being pulled underground, for example through a drilled hole. Attaching the adaptor to the pipe end prior to the pipe being pulled underground is faster and reduces danger to workers compared to the conventional process of attaching the adaptor to the end of the pipe after the pipe has been pulled underground.

IPC Classes  ?

• F16L 1/032 - Laying or reclaiming pipes on land, e.g. above the ground in the ground the pipes being continuous
• F16L 55/30 - Constructional aspects of the propulsion means, e.g. towed by cables
• F16L 1/00 - Laying or reclaiming pipesRepairing or joining pipes on or under water
• F16L 101/50 - Pulling cables or the like
• F16L 3/10 - Supports for pipes, cables or protective tubing, e.g. hangers, holders, clamps, cleats, clips, brackets substantially surrounding the pipe, cable or protective tubing divided, i.e. with two members engaging the pipe, cable or protective tubing
• F16L 55/115 - Caps
