MODEL: BCQ Series
Thermal Stress Compensator
Overview
During steam injection, axial casing stress caused by temperature changes acts on both ends of the thermal compensator.
Relative movement between the mandrel and outer tube compensates for small casing expansion and contraction, reducing thermal-stress damage and protecting completion strings in directional and horizontal thermal-recovery wells.

Product Advantages
- The preload protection device has strength performance consistent with the selected casing.
- Good gas-tightness helps prevent leakage during cementing, steam injection and thermal recovery.
- When used with prestressed cementing processes, the tool further helps prevent casing damage.
