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

PW casing tubing

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

●Tubing properties meet the industry standard

PW casing tubing thread

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

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

PW casing tubing heat treatment(Option)

●Provides higher material strength

●Whole casing Heat treated significantly increases casing life

PW casing tubing case hardening(Option)

●PW 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
