Cross over Sub Drilling, also known as Cross Sub Drilling, is a specialized tool or method in drilling technology. Crossover Sub is a connecting tool used to connect and convert different drill pipes or tools during the drilling process to meet different formation conditions and drilling needs.
The main characteristics of cross drilling products are their high adaptability and flexibility. It can convert between different drilling tools, allowing drilling operations to be adjusted and optimized according to actual situations. For example, when encountering hard formations, drilling tools with stronger drilling capabilities can be used; When encountering loose formations, more suitable drilling tools can be replaced.
Short-circuiting solves the problem that the upper and lower drilling tools have different thread buckle types and cannot be sefely conneted.The products are made Of high-performance alloy materials,such as 415H and other high-quality alloy steels.
Thread type:IFPEGNCFH,the thread is desalinated,the life is longer,the connecting Thread is produced according to the standard specifications,and after strict testing ,To ensure the precise link of the drill tool products
| 1.(dia)size mm | 80-240mm |
| 2.Material | 4145H |
| 3.Thread connection | Pin*box(IF,REG,NC,FH) |
| 4.Application | During the drilling process, it is necessary to pass the relevant conversion joints to solve the problem that the threaded fasteners Of the upper and lower drills cannot be safely connected. |
