Product Description--Conductor Pipe
Conductor pipe is a large diameter pipe set into the seabed to provide the initial stable structural foundation for a borehole or oil well. As the first string of casing, it’s the largest diameter pipe installed in a well.
LC-Series is special designed for CNOOC South China Sea platforms.It is mainly used in the operation of jetting-in application. It includes LC-1,LC-2 and LC-4 and it is composed with high-impact alloy steel.
Feature:
1）LC-1 is single-threaded and it takes 6 turns to fully make-up;
2）LC-2 is double-threaded and it takes 2 turns to fully make-up;
3）LC-4 is four-threaded with advantage of making up in only 3/2turns.
4）Describe
The four embedded lock device can effectively prevent thread back-off from the impact loads generated during hammer piling operation.
