Predominantly incorporated into a braided line toolstring, the releasable shear pin sub can be parted by applying an overpull greater than the tensile rating of the shear pin connecting the sub together. The rope socket, upper section of the releasable shear pin sub and the cable can then be retrieved back to surface leaving a clean fish neck to allow for subsequent recovery of the toolstring remaining in hole.
TOOL APPLICATIONS:
As a reliable release mechanism in the event a toolstring becomes stuck
DESIGN FEATURES & BENEFITS:
Multiple shear pin options for operational flexibility
Knurled sleeve to retain shear pin remnants after shearing
Locking screws to retain shear pin remnants after shearing
No complex hydraulics or drop bar required for tool release
Connection options to suit customer requirements
Simple, robust design ensuring ease of operation for the end user
Selected components QPQ treated
Hexagonal flats for safe make-up & break-out
Accurate shear pin values can be ascertained with the LiMAR® Shear Pin Tester for configuring the Releasable Shear Pin Sub
