MAZIER RETRACTABLE CORE BARRELS

Jan 26, 2018

The Mazier Retractable Core barrel allows taking an undisturbed sample of soil by applying pressure. The rotation includes a frictionless design to have well coefficient close to zero.


The axial movement of the shoe from the bit allows an adaptation to the encountered formation which might be of different hardness and this without affecting the quality of sampling. The shoe being ahead of the bit stops the water to erode and disturb the core.


Characteristics:


1.Nil wall co-efficient

2.Entry Coefficient 3.5%

3.Grey/Clear polyethylene tube

4.Length of sample: 1,000mm(1m)

5.Sealed head dampened with oil

6.Moving head in hard chromed steal placed in bronze bearing.
