Product Description

Oilfield API Standard Mechnical Stage Collar

This tool continues to be the subject of research and development to find new materials for faster drillout time, greater PDC bit drill-ability and better metal-tometal sealing.

Oilfield API Standard Mechnical Stage Collar

Tools can be made from material grades up to 135,000 psi min yield, including material suitable for sour gas service.
All parts are custom fitted and subjected to extensive quality control standards for maximum performance downhole.
No welds are used on any portion of the tool.
The reduced length of the tool minimizes the effect of bending stresses.
The pressure-relief design prevents fluid trapping and compression between the opening device and the closing plug during the closing phase of the tool’s operation.
The closing sleeve is held in the closed position by an internal lock ring.
Both the opening and closing sleeves lock against rotation for easy drill-out.
A min amount of aluminum and rubber are the only materials encountered during drill-out. Plug sets for four different cementing applications are available.
