Set of 25 Casing Tubes (56 mm)
Casing tubes are generally applied when working in unstable soils or working over water or in other situations where the risk of buckling or breaking of the CPT sounding tubes is present through insufficient lateral support. The casing tubes are placed when the CPT string, after having penetrated a soft layer of considerable thickness with little lateral support, hits a much harder layer. The CPT testing procedure is interrupted and the casing tubes are placed. A casing cutting shoe of hardened steel is put on the first casing tube in order to protect the otherwise exposed thread.
The set comprises 25 casing tubes with GMF type trapezoidal thread. The casing cutting shoe is subject to wear and is to be purchased seperately.
