Liner Hangers

The liner is mostly applied during and after liner cementing operation. For different types of hanging, the liners are divided into three categories: mechanical, hydraulic and mech-hydro. The liner hangers can be used for running casing, hanging, backing off washing the connecting liner and etc.

Stage Cementing

The ID of upper and lower sub is equal to that of casing, but smaller than that of closing sleeve, eliminating the possible damage to the closing sleeve during tripping or drilling out accessories.

All accessories are non- rotating and made of easily drillable materials.
