AISI4130 Kernstoßbohrer-äußere Funkleitungs-nahtloses Bohrgestänge
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
