HW DCDMA Borehole Wireline Drill Pipe Casing For Geotechnical Environmental Drilling
HW DCDMA borehole wireline casing tubes
This casing is intended for single use or situations where the casing is left in the hole. The HW
casing is made from DCDMA tubing and utilize the DCDMA W thread form. The HW thread is a
straight thread (4 threads per inch). This casing is universal in design and can be used in any drilling
application where threaded casing is required to be left in the ground.
