Main Application
The casing are designed to perform cased holes. Especially for the construction of bored piles by rotary drilling rigs the casing joints due to the machning accuracy guarantee a fast placement and bolting of the casing as welll as best force transmisssion
Product Description
Double-wallled casing can be used universally,as they are designed especiallly for transmitting high rotational annd vertical forces as created by the ratary drives and oscilllators. The use of double-walled casing ensures a flush drill string. Single-walled casings can be used for appllications where weight reduction is importannt.
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 diffcult.
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 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
