BW casing is intended for single use or situations where the BW casing is left in the hole. The BW

casing is made from standard tubing and with the BW casing thread form. The BW casing thread is a

straight thread (4 threads per inch). This BW casing is universal in design and can be used in any drilling

conditions where threaded BW casing is required to be left in the ground.

BW casing tubing

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

●Tubing properties meet the industry standard

BW casing tubing thread 

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

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

BW casing tubing heat treatment(Option)

●Provides higher material strength

●Whole casing Heat treated significantly increases casing life

BW casing tubing case hardening(Option)

●BW 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
