Casing and Pipe cutting equipment
    click:400     adddate:2018-6-9
Single-Trip Casing Cutting System was designed to speed up and simplify the mechanical
abandonment operation. It removes the need for the old fashioned marine swivel and the heavy, rigid and hard to
handle drill collar string. The system speeds up the handling of the cutting string as only one stand of 8" drill collars
need to be run above the cutting assembly.
 pipe cuers range in size from 3 5⁄8" OD to 16" OD and will cut 4 ½" to 36" casing. The pipe
cutter works on the principle of pressure drop across an orifice, which in turn forces the cutting blades into the open
position. The tool is equipped with a piston position indicator which enables the operator to be positive that a cut
has been achieved.
