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.
Especially for the so-called “Deep Sounding” projects and nearshore CPT testing Gouda-Geo has developed the heavy-duty CPT sounding tubes with an outer diameter of 44 mm.
When you contemplate to use these tubes, please realise that most probably your push-and-pull clamp needs to be adapted. Gouda-Geo supplies a set of 2 clamping block holders with 44mm clamping blocks and a set of 2 filling plates who keep the clamping blocks in place to make the CPT push-and-pull clamp suitable for these 44 mm CPT sounding tubes.
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 44 mm CPT sounding tubes are provided with Round Tapered Thread (RTT), a single-entry rope thread. The main advantages are the improved strength of the thread and the relative ease to clean it.
