Features of Non-Rotating Equipment.
- Easily drillable with PDC or standard bits
- Non-Rotating lockout between male & female parts takes place after & separate from radial guidance
- Drive faces are radially miss-aligned from locating faces so that the two parts are axially locked to prevent axial bounce back
- Guidance/locating mechanism is designed to ensure axial positioning regardless of borehole angle
- Burst discs are positively machined to give burst pressure and can be modified to customer demands
- The underside of the burst disc is cross-grooved to ensure controlled fragmentation fragment size having been pre-determined to pass through the float valve
