ROTB & ROTH Equalizing Sub
Rebco ROTB & ROTH Equalizing Subs are to be used with Sub-Surface Controls such as Locking Mandrels. Both Equalizing Subs are identical except the ID is larger in ROTH Equalizing Sub.
These Sub-Assemblies are designed to allow pressure differentials to be equalized across the Lock Mandrels and Flow controls before attempting to retrieve them.
Product Code: 20
Applications
Equalizing pressure across Lock Mandrels and flow control devices in 2", 2-1/2", and 3" nominal sizes before retrieval attempts
Applications requiring a small, controlled equalization flow rate using the .003" orifice (ROTB), a moderate flow rate using the .006" orifice (ROTH), or a larger flow rate using the .011" orifice variant
Any completion where trapped pressure below a set lock mandrel must be safely bled off prior to pulling operations
Key Benefits
Three orifice sizes (.003", .006", .011") provide graduated control over the equalization flow rate, allowing the operator to match the equalization speed to the well's pressure conditions and the sensitivity of adjacent equipment.
Identical dimensions across the ROTB and ROTH simplify inventory; the only difference between the two is the orifice size and minimum ID.
Stainless Steel construction provides corrosion resistance for long service life in aggressive downhole environments.
Available in a variety of materials suitable for specific downhole conditions.
NOTE: These types of Equalizing Subs require running/pulling equalizing prongs. Equalizing Subs are available in variety of Materials, suitable for down-hole conditions.
