Seamless Mining Drill Pipes for Diamond Drilling Rods

Wireline Core Barrel Outer Tube WLA/WLB/WLN/WLH


Tubes should be made seamless. Outer tube rolling technique and machining operations are optional.

Core Tube straightness is checked by rolling the tube on a horizontal or slightly inclined flat surface. 

When rolling, no clearances shall be seen between the rod ends and the surface, nor between the middle

of the drill rod (core tube) and the surface.

International Standard ISO 10097-1 was prepared by Technical Committee ISO/TC 82, Mining, Subcommittee

SC 6, Diamond core drilling equipment.
