Product Description
Seamless Mining Drill Core Tube for Diamond Rock Drilling Inner tubes
SAE1541/AISI1541 Wireline Core Barrel Inner Tubing 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.
ISO 10097 consists of the following parts, under the general title Wireline diamond core drilling equipment —
