Rotary Borehole Drilling Rigs Spare Parts Conductor Casing

We Are China Gold Supplier Certified By Alibaba And Germany TUV Rheinland

The casing are designed to perform cased holes, especially for the construction of bored piles by rotary drilling rigs. The casing joints with high machining accuracy guarantee a fast replacement and bolting of the casings as well as the best force transmission effect.

We offers two types of casings:

Double-walled casings

Single-walled casings

Double-walled casings can be used universally, as they are designed especially for transmitting high rotational and vertical forces as created by the rotary drives and oscillators. The use of double-walled casings ensures a flush drilling string.

Single-walled casings can be used for applications where weight reduction is important.

Tips of casing and tubing for piling project

1. The pipe casing should avoid to the collision, especially of casing joints knock against when install the casing bolts, it must be clean, otherwise it will cause the difficult installation.

2. The drilling bucket needs to be chiseled in advance when pile casing drives the increased torque to difficult.

3. The drilling bucket needs to be checked position and verticality of hole, to avoid opening the door at the hole bottom when lift the drilling open and closed again against to casing shoes.

4. You must be tested all movements of pulling machine normally before concreting. Pull up pipe casing immediately to prevent steel trunk floating after the end of grouting.

UNIMATE also offers accessories like casing drive adapter, casing joints and casing shoes/blocks, etc.

The development of a casing shoe fitted with pin-on teeth is the result of years of experience of drilling casing boreholes in difficult soil formations. The casing shoe is particularly suitable for formation of rock sockets and the construction of bored pile walls.
