There are lots of varieties of rope socket in most typical use: Knot sort, teardrop sort and braided sort. The rope_socket is required to make connection between wireline and toolstring. The essential toolstring parts are rope_ socket, knuckle joint, stem, mechanical jars, and so forth.
The teardrop (additionally known as a ‘no-knot’ or ‘wedge’ sort) is designed for 0.092″, 0.105″, 0.108″, 0.125″ and is designed O.D for 1-1/4″, 1-1/2″, 1-7/8″, 2-1/8″, 2-1/2″.
The usual physique of teardrop has an inside taper to simply accept the thimble. Nevertheless a thimble eye is accessible to transform the older type of rope socket.
The top of the wire is bent to suit the curve on the backside of the teardrop, with the brief aspect barely shorter than the aspect of the thimble.
The groove within the thimble of this socket just isn’t deep sufficient to accommodate the full thickness of the wireline. Because the safety of the wirelne relies upon upon its being pinched between the thimble and it physique. Care should be taken to make sure the right dimension of socket is chosen for the wireline in use.
As the inner parts of the teardrop rope socket don’t allow the wire to rotate, it’s important to incorporate a swivel instantly under it.
Don’t substitute a knuckle joint rather than a swivel. A swivel has 11/2 levels to five levels of lateral motion, the place a knuckle joint just isn’t designed to rotate
underneath load and has 15 levels of lateral motion. Within the occasion of it being essential to fish the rope socket, a knuckle joint will enable it to put over towards the aspect of the tubing wall at an angle which can make latching tough / inconceivable.
