HW casing is intended for single use or situations where the HW casing is left in the hole. The HW casing is made from standard tubing and with the HW casing thread form. The HW casing thread is a straight thread (4 threads per inch). This HW casing is universal in design and can be used in any drilling conditions where threaded HW casing is required to be left in the ground.

HW casing tubing

●Parallel wall tubing compatible with HQ wireline coring system in hole tools

●Tubing properties meet the industry standard

HW casing tubing thread

●Longer threads (4 threads per inch) provide strength in driving and jarring

●Standard HW casing thread provides sufficient strength for most drilling conditions

HW casing tubing heat treatment(Option)

●Provides higher material strength

●Whole casing Heat treated significantly increases casing life

HW casing tubing case hardening(Option)

●HW casing Pin thread crest is hardened to nominal 50-55 HRC to eliminate damaging’adhesion’ wear

●Eliminates the transfer of wear material back and forth as seen between threads of equal

hardness, leading to large scale galling and joint seizing
