PWT casing is engineered to surpass expectations for a casing and features quicker make-up and easier break-out characteristics than the standard HW casing. PWT casing thread works well under difficult drilling conditions and is designed for repeated application. The PWT casing is made with standard tubing and the tapered PWT casing thread provides increased strength and easier make and break-out (2.5 threads per inch).PWT casing is universal in design and can be used in any drilling conditions where threaded PWT casing is required to be left in the ground. And PWT casing could be used as drill rod.

PWT casing tubing

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

●Tubing properties meet the industry standard

PWT casing tubing thread 

●PWT Tapered joint and fewer threads per inch result in easier and faster make and break for reduced wear and reduced labor costs

●Double-butt tapered joint and heavy duty buttress thread form provide greater torsion and pullback strength

●Tapered thread reduces stress and provides a rigid joint to reduce movement and lubricant loss

●Load efficiency of 40% provides greater pullback strength to allow retrieval from difficult ground conditions and repeated use

●PWT Thread is easier to clean due to wider spacing of the threads for situations where casing is reused

PWT casing tubing heat treatment(Option)

●Provides higher material strength

●Whole casing Heat treated significantly increases casing life

PWT casing tubing case hardening(Option)

●PWT 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
