Double Wall or Single Wall Casings for Rotary Drilling Rigs or Casing Rotators / Oscillator
- Permanent/ temporary casings optional
- Diameter up to 5000mm
- All FES casing joints are made from high quality steel with special heat treatment to improve torsional strength
- Forged/ Casted joints are optional
- Computerized machinery is employed to achieve precise measurement.
- Regular FES casing tubes are made from Q355B steel, with joints made from 25CrMo after special heat treatment. Heavy duty material such as NM360 tubes and forged joints are available as options.
FES provides both single wall and double wall casing. The dimensions of FES casing are designed to match most casing brands in the global foundation drilling market.
- Double wall casing is for temporary using, which is designed especially for transmitting high rotational and vertical forces created by the machine.
- Single wall casing is usually for permanent using, which is mostly used in the soft condition and the pile doesn’t have to be too deep.
