DCDMA Stadnard W Series Steel Casing Used High Strength Steel
Tubing for High Torque Drilling
Steel Casing
ROSCHEN Group Limited manufactures the largest variety of Grout
Casing in the industry and stocks a full line of "W" series casing
made of high strength steel tubing.
ROSCHEN Group Limited uses top quality 4130 grade material; our
in-house engineers have designed field-tested dual and triple lead
threads as well as developed several thread designs to meet
individual contractor’s needs and industry standards.
"W" series steel casing offers the extra strength of double butt
joints and added ease in cleaning threads. Our casing is flush
threaded inside and out and, because of it’s' "W" series design, it
does not require the use of coupling. The outside diameter of each
size casing will fit the hole drilled by the next larger size core
bit and dimensional design also allows one size of casing to fit
within the next larger size.
Standard for quality, ROSCHEN Group Limited casing meets or exceeds
all DCDMA standards for uniform concentricity, size, material and
threads and each piece is inspected for tight tolerance by a
skilled staff of CNC operators.
