RELEASING SPEAR ACCESSORYS

Segment-Type Spear Grapple The Segment-Type Spear Grapple enhances the spear’s effectiveness by providing an extended catching range beyond the maximum range of the standard one-piece grapple. TIANHE Segment-Type Spear Grapple is used in place of the standard one-piece Grapple on the 9 5/8” Spears. This enhances the spear's capability of engaging up to 20". Segment-Type Spear Grapple consists of a grapple body, eight grapple segments, two retainer rings, six retainer ring screws, six retainer ring spacers, and sixteen grapple segment screws

Pack-off Assembly

Pack-off Assembly is available for all TIANHE Spear Assemblies and is designed to efficiently pack-off all sizes of tubing and casing. Circulation through the fish is enabled by attaching the Spear Pack-off Assembly to the bottom of the spear with a sub type nut.

Spear Stop Sub

The TIANHE Releasing Spear Stop Sub Assembly is an accessory designed to convert a releasing spear with a flush-type mandrel into a shouldered type spear. It is installed in the box connection at the top of the mandrel when    the use of a positive stop is desired or required. A stop ring can be added     to increase shoulder diameter. All stop rings are furnished with left-hand threads.

Optional Nuts

Mill Type to mill away burrs, Sub Type to connect and run other tools below the Spear, and Sidehill Type to center the spear in greatly oversize holes to assure entry of the Spear into the fish.
