The Geomil sounding tubes have a standardized OD of 36 mm with an ID of 16 mm. The steel quality is carefully chosen to provide the highest possible quality and tightest possible tolerances. Every single tube is gauged five times during production. This guarantees a constant quality and conformity with the most stringent standards regarding dimensions, straightness and thread tolerances (e.g. the NEN-5140).

 

Machining the threads follows a fully automatic and robotized sequence, allowing us to ensure a constant quality and conformity with the most stringent standards regarding dimensions, straightness and thread tolerances (e.g. the NEN-5140). On request, we send a tube certificate when supplying the tubes.

 

Next to the three GeoMil thread types "Speedlock", "Heavy" and "Standard", any third party thread type can be machined as well.

 

All GeoMil tubes can be delivered from stock for the standard lengths of 1 000 mm, 500 mm and 300 mm. Bulk quantities and/or special lengths can be produced within a couple of days.

 

For connecting tubes, friction reducers or cones coming with different thread types (also non-GeoMil) we provide respective cross-overs and adapters in various lengths.
