SWT Casing Tube used for ODEX Eccentric Overburden Drilling
Steel Casing
Roschen 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 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 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.
Roschen manufactures a large variety of Flush Joint Casing from top
quality 4130 grade material, heat treated ends are available at an
additional cost, 1026 and N-80 grade materials are available at
reduced pricing and left-hand threading is available at no
additional cost.
