Abstract
Male and female thread protectors for the box and pin ends of pipe sections are removed by an apparatus including a first operating head for attachment to a rotary driving tool which has two pins of extending longitudinally of the rotary axis which are pointed so as to punch through a transverse inner circular web of the male protector to form openings and a second operating head having two pins mounted for adjustment of a position radially from the axis so as to accommodate openings in the transverse outer circular web of the female thread protector which are of different spacing.

Apparatus for use in removal of thread protectors for male and female ends of pipe sections where the male end includes an external male thread and the female end includes an internal female thread;
- where, at the female end of the pipe section is provided a male thread protector with a cylindrical sleeve which inserts into the female end of the pipe section and carries an exterior thread thereon threaded into the female thread on the pipe section;
- where the cylindrical sleeve of the male thread protector is closed across an inner end of the sleeve with a transverse inner circular web which is thus located inside the female end of the pipe section;
- where, at the male end of the pipe section is provided a female thread protector with a cylindrical sleeve which surrounds the male end and carries an interior thread thereon threaded onto the male thread on the pipe section;
- where the cylindrical sleeve is closed across an outer end of the sleeve with a transverse outer circular web which is thus located outside or beyond the male end of the pipe section;
- the apparatus comprising:
- a first operating head having a coupling for attachment to a rotary driving tool for rotation about a drive axis and a first connector portion for engaging and applying torque from the rotary driving tool to the male thread protector at the transverse inner circular web;
- and
- a second operating head having a coupling for attachment to a rotary driving tool for rotation about a drive axis and a second connector portion for engaging and applying torque from the rotary driving tool to the female thread protector at the transverse outer circular web.
Apparatus for use in removal of thread protectors for a female end of pipe sections where the female end includes an internal female thread;
- where, at the female end of the pipe section is provided a male thread protector with a cylindrical sleeve which inserts into the female end of the pipe section and carries an exterior thread thereon threaded into the female thread on the pipe section;
- where the cylindrical sleeve of the male thread protector is closed across an inner end of the sleeve with a transverse inner circular web which is thus located inside the female end of the pipe section;
- the apparatus comprising:
- a first operating head having a coupling for attachment to a rotary driving tool for rotation about a drive axis and a first connector portion for engaging and applying torque from the rotary driving tool to the male thread protector at the transverse inner circular web;
- and
- wherein the first operating head includes two pins extending parallel to the drive axis for engaging into openings in the transverse inner circular web of the male thread protector.
Apparatus for use in removal of thread protectors for a male end of pipe sections where the male end includes an external male thread;
- where, at the male end of the pipe section is provided a female thread protector with a cylindrical sleeve which surrounds the male end of the pipe section and carries an interior thread thereon threaded onto the male thread on the pipe section;
- where the cylindrical sleeve is closed across an outer end of the sleeve with a transverse outer circular web which is thus located outside or beyond the male end of the pipe section;
- the apparatus comprising:
- an operating head having a coupling for attachment to a rotary driving tool for rotation about a drive axis and a second connector portion for engaging and applying torque from the rotary driving tool to the female thread protector at the transverse outer circular web;
- wherein the operating head includes two pins extending parallel to the drive axis for engaging into openings in the transverse outer circular web of the female thread protector;
- and wherein the two pins of the second operating head are mounted for adjustment of a position thereof radially from the axis so as to accommodate openings in the transverse outer circular web of the female thread protector which are of different spacing.
