DCDMA W Thread / Premium WT Thread Pipe Casing for exploration core drilling

DCDMA W Thread / Premium WT Thread Pipe Casing for exploration core drilling


Quick Detail:


W Casing

WT Casing

Metric Casing

W Series DCDMA



Description:


Casing

Roschen manufactures and distributes Industry-standard DCDMA W thread and premium WT thread.


W

This casing is intended for single use application, or situations where the casing is left in the hole. The W casing is made from DCDMA C80 tubing and utilizes the DCDMA W thread form. Featuring a straight thread, this universal casing design can be used in any drilling application where threaded casing is required to be left in the ground.


Tubing

Parallel wall tubing is compatible with Q/E wireline in-hole tools, and standard DCDMA W sizes allow nesting of other W casing.


Thread design

Double-butt joint provides strength in driving and jarring.


WT

This casing is engineered to surpass expectations and features quicker and easier make and break characteristics than the standard W casing. This thread works well under difficult drilling conditions and is designed for repeated application. The WT casing is made with DCDMA C80 tubing and the tapered HD thread provides increased strength.


Tubing

Parallel wall tubing is compatible with Q/E wireline in-hole tools, and standard DCDMA W sizes allow nesting of other W casing.


Thread design

Compatible with HD rod threads.

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.

Threads are easier to clean due to wider spacing of the threads for situations where casing is reused.
