Introducing New Threads for CPT Tubes

The newly developed Gouda Heavy Duty (GHD) thread is destined to become the new standard screw thread for the 36 and 44 mm CPT tubes, the 56 mm casing tubes and the new generation of 10 cm² and 15 cm² piezocones. The thread has many advantages over the threads currently available:

  • Optimal balance between male and female threads
  • Single-entry thread, so much less susceptible to loosening during the CPT process
  • Only 3 revolutions required to close or open
  • Easy to clean with a steelwire brush
  • Closes superbly resulting in a very good resistance to water inflow
  • Cross-over tubes are no longer needed
