Mechanical Two Stage Cementing Collar (Ve-102-MST)
Product Details
Vishal Engineering Mechanical Stage Collar has been designed for stage cementing operations that require the tool to be opened mechanically. The tool features two internal sleeves that shift during the stage cementing operations. The bottom sleeve is shifted open by dropping an opening dart and allowing it to set on the opening seat. Closing the stage collar is achieved by pumping a closing plug behind the second stage cement and applying pressure upon completing displacement.
