һSummary

The Inside Bop is a heavy-duty drop check valve with a conical plug to reduce the cutting action of the mud on the valve seat, ensuring positive closure whenever required. Standard inside BOP units are designed for service pressures up to 10,000psi

Structure & Principle

Installed in the drill string, it can protect the rotary swivel, rotary hose, stand pipe, and mud pumps from drill pipe kicks. It may be used along with high-pressure pumps to maintain well control by preventing high-pressure backflow.(Figure)

Usage

A special release tool allows the valve to be held open to permit sabbing into position against a backflow of fluid, this optional release tool can be installed on the float valve and the entire assembly kept ready on the rig floor for quick installation at the first signs of serious backflow when drill pipe is pulled from the well.

ġMaintenance

Through Ultrasonic testing and Magnetic testing the body is proved up to grade. The threads are protected to prevent corrosive. Cleaning all parts and spares.
