FEATURES AT A GLANCE

Roller Centralizer

The roller reduces the inlet resistance of casing, tailpipe or screen tube, improves the success rate of lowering the pipe column, and reduces the working time and cost.

The roller centralizer reduces the contact area between the centralizer and the open-hole well wall, and reduces the risk of the pipe string pressure difference being stuck.

The roller centralizer can provide better support and improve the cementing effect.
