Torque Rings
Rings with colour coding depending on their width.
Advantages
- increase the torque of a standard threaded connection;
- protect against sand ingress and prevent contamination of the connection;
- improve the sealing of the connection;
- allow rotation of the casing string to overcome friction and downhole obstructions under complicated conditions.
Specifications
- applicable connection threads: ОТТМ, БТС
- colours by ring width: green, red, blue, yellow
- torque increase: 20 to 40 kN·m
- casing sizes (ОК): 114; 140; 178
Application area and experience
Torque rings are designed for run-in operations of both cemented and non-cemented casing strings; they increase the strength and the allowable torque of standard threaded connections and provide a full-bore diameter along the entire length of the casing string.
