YFZ-A STAGE CEMENTER
Features:
- The internal-closing structure and non-rotating closing sleeve design eliminate the possible damage to the closing sleeve when drilling out accessories.
- The pressure-relief design eliminates fluid trapping and compression which might occur while opening and closing the side ports.
- All accessories are non-rotating and made of easily drillable materials.
- A pump-down opening plug instead of a free-fall opening plug can be used for a continuous two-stage cementing operation.
