W and WT Series Flush Joint Casing
DPI Casing is available in multiple Grades:
W series casing
"W" series casing
We use Premium alloy steel when the casing is being re-used on an
everyday basis and is subject to both drilling and driving
applications. Where operations entail less abuse, we can suggest
casing with slightly lower strength specifications.
Example:
Pre-collaring a shallow bore hole, and expecting to leave the
casing in place - we will match this application with a steel that
will do the job and provide you value.
WT series casing
"WT" series casing
We can also recommend a thread profile and advise you of the
benefits and limitations of each, "W" (Square thread) or WJ
(Tapered thread), that best matches your product use.
All Casing is threaded in one of our CNC Machining Centers. Each
thread is checked and rechecked with our DCDMA Certified Gages -
always part of our Quality Assurance Program.
