Abstract
A method and apparatus for pulling multiple joints of pie which comprises a pulling section and a pulled section, the method and apparatus working while the joints of pipe are below grade and capable of pulling multiple joints of pipe without relocating the pulling section.
Claims20
A method of making up a string of pipe from a plurality of joints of pipe comprising the steps of:
- (a) providing a pipe joint pulling tool having:
- (i) a pulling section which is detachably connectable to a first joint of the plurality of joints of pipe to be made up;
- (ii) a pulled section which is detachably connectable to a second joint of the plurality of joints to be made up;
- (b) attaching the pulling section to the first joint and attaching the pulled section to the second joint, wherein the pulling section is spaced apart from the pulled section and the pulling section and pulled section are operatively connected together;
- (c) after step “b” while the pulling section is attached to the first joint, the pulling section pulling on the pulled section and causing the first and second joints of pipe to be made up by the pulling closer the spaced apart pulling and pulled sections;
- (d) wherein, after step “c” the pulled section is detached from the second joint of pipe and detachably connected to a third joint of pipe from the plurality of joints of pipe, and while the pulling section is attached to the first joint, pulling on the pulled section causing the third joint of pipe to be made up to the plurality of joints of pipe.

A method of making up a string of pipe from a plurality of joints of pipe comprising the steps of:
- (a) providing a pipe joint pulling tool having:
- (i) a pulling section including first and second powered cylinders which are independently laterally adjustable, the first cylinder being connected to a first clamping belt and the second cylinder being connected to a second clamping belt, and which are detachably connectable to any selected one of the plurality of joints of pipe to be made up using at least one of the first or second clamping belts;
- (ii) a pulled section including first and second connectors which are independently laterally adjustable, and which is detachably connectable to any selected other of the plurality of joints to be made up using at least one clamping belt;
- (b) attaching the pulling section to a first joint from the plurality of joints of pipe and attaching the pulled section to a second joint from the plurality of joints of pipe, wherein the pulling section is spaced apart from the pulled section and the pulling section and pulled section are operatively connected together using at least one of the first or second clamping belts;
- (c) after step “b” while the pulling section is attached to the first joint, the pulling section pulls on the pulled section and causes the first and second joints of pipe to be made up by the pulling closer the spaced apart pulling and pulled sections;
- (d) wherein, after step “c” the pulled section is detached from the second joint of pipe and detachably connected to a third joint of pipe from the plurality of joints of pipe, and while the pulling section is attached to the first joint, pulling on the pulled section and causing the third and second joints of pipe to be made up by the pulling closer the spaced apart pulling and pulled sections.

An apparatus for making up a string of pipe from a plurality of joints of pipe comprising a pipe joint pulling tool having:
- (a) a pulling section including first and second gas powered cylinders which are independently laterally adjustable, and which is detachably connectable to a first joint of the plurality of joints of pipe to be made up using at least one clamping belt, the first and second gas powered cylinders being powered by a portable supply of compressed gas;
- (b) a pulled section including first and second connectors which are independently laterally adjustable, and which are is detachably connectable to a second joint of the plurality of joints to be made up using at least one clamping belt.
