CPT Sounding Tubes (36 mm)

CPT sounding tubes(36 mm) for push the electrical or mechanical cone into the ground by means of a CPT penetrometer pushCPT sounding tubes(36 mm) for push the electrical or mechanical cone into the ground by means of a CPT penetrometer push

CPT sounding tubes are used to push the electrical or mechanical cone into the ground by means of a CPT penetrometer pusher. Gouda-Geo CPT sounding tubes meet the highest quality standards. The tube material is manufactured by one of Europe's leading steel manufacturers according to our own standards. No distinction whatsoever is made between tubes for 100 kN and 200 kN testing. All tubes are suitable for any pushing force and for any type of test, i.e. electrical or mechanical Cone Penetration Testing.

During production every single tube is checked automatically by means of sensors integrated in the lathe machine in order to comply with all national and international standards.

The CPT sounding tubes are available with the following threads:


STANDARD (STD) Tapered Thread

This thread is called STANDARD, since it has been used by the CPT industry since the 1950-ies. Originally designed by Delft Geotechnics it has been adopted by all manufacturers of CPT equipment. Its advantage is that it is the world standard. It does not feature the advantages of its modern counterparts.

  • Effective length: 1,000 mm
  • Outer diameter: 36 mm
  • Inner diameter: 16 mm
  • Weight: 6.5 kg
  • Required number of turns to lock / unlock: 7


QUICK-LOCK (QLK) Double-Entry Rope Thread

By half of the 1990-ies CPT has become more-and-more a highly productive industry. Operators make up to 14 tests of 25 meter per 8-hour shift. Strain-injuries in wrists and elbows are becoming a real issue and the industry asks for a newly designed thread. This resulted in the Quick-Lock thread (also called Speed-Lock thread).

The main advantages are the number of turns required to lock / unlock (only 2.5 turns), the improved strength of the thread (over 40% stronger than the STANDARD thread) and the relative ease to clean it.

  • Effective length: 1,000 mm
  • Outer diameter: 36 mm
  • Inner diameter: 16 mm
  • Weight: 6.5 kg
  • Required number of turns to lock / unlock: 2.5


AR Tapered Rope Thread

Originally designed in the 1970-ies by A.P. van den Berg as a modern version of the standard tapered thread (see earlier). The mayor advantage was, that the relatively sharp thread was replaced by a much more easier to clean rope thread. The dimensions of the male and female thread are more in balance, making it somewhat stronger than the standard thread.

  • Effective length: 1,000 mm
  • Outer diameter: 36 mm
  • Inner diameter: 16 mm
  • Weight: 6.5 kg
  • Required number of turns to lock / unlock: 6.5


2R Tapered Rope Thread

Designed in the 1990-ies by A.P. van den Berg with the same design requirements as the earlier mentioned QLK double-entry rope thread. This thread was not designed from scratch, but based on the existing AR tapered rope thread.

The main improvement of the 2R thread over the AR thread is the number of turns required to lock / unlock (3.5 turns). It was not stronger than the AR thread and not as easy to clean as the QLK thread.

  • Effective length: 1,000 mm
  • Outer diameter: 36 mm
  • Inner diameter: 16 mm
  • Weight: 6.5 kg
  • Required number of turns to lock / unlock: 3.5
