ISO10097-1 SAE1541 Wireline Diamond Seamless Mining Drilling Mother Pipes
WLA/WLB/WLN/WLH Diamond Wireline Drilling Rods Core tubes Drilling Inner tubes
and Drilling outer tubes
1.1 General
All Drill Rods and Core Tubes made from seamless cold drawn tubes or cold rolled steel tubes.
All dimensions and tolerances are in millimetres unless otherwise stated and shall be in accordance with Tables 3 to
9 inclusive wireline rock drilling rods.
1.2 Conformity
In those industries where drilling depths are measured in metres, the rod lengths shall be 3 m, 1,5 m or 0,75 m. But
when wireline drilling in conformity with DCDMA and CDDA standards, the lengths of rods may be 3,048 m, 1,524 m or
0,762 m.
1.3 The steel tube Eccentricity
The eccentricity is defined as the distance between the centres of the outer and inner diameters and may not
exceed 10 % of nominal wall thickness Q.
The eccentricity is calculated according to the formula:
Qmax - Qmin/2QnomX100
where Qmax and Qmin are measured values in the same section.
1.4 The Drill Pipes Straightness
When measured over the whole length of the Steel tube by rolling against a straightedge, the maximum deviation shall not
be greater than:
¾ for drill rods 1 in 2 000;
¾ for core tubes 1 in 1 500.
