Equalizing Sub-Assemblies
EQUALIZING SUB-ASSEMBLIES provide means of equalizing pressure across Sub-Surface
Controls such as Locking Mandrels and Tubing Mandrels.
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.
ROTF Equalizing Sub
Rebco ROTF Equalizing Subs are to be used with Sub-Surface Controls such as Locking Mandrels. Type ROTF Equalizing Subs can be supplied with 2 or 3 Orifice Ports.
These Sub-Assemblies are designed to allow pressure differentials to be equalized across the Lock Mandrels and Flow controls before attempting to retrieve them.
NOTE: These types of Equalizing Subs require running/pulling equalizing prongs.
ROTXR Pump-Through Bottom Sub-Assembly
Rebco ROTXR Pump-Through Bottom Sub-Assemblies are to be used with Lock Mandrels and Equalizing Valves (Valve type) according to the Nominal Size and Profile of the Landing Nipple.
Spring loaded Ball and Seat bottom holds pressure from below only and provide the means of pumping through the Plug.
BB Circulating Bottom Sub-Assembly
Rebco BB Circulating Bottom Sub-Assemblies for use in BF Landing Nipple are to be used with Lock Mandrels (See Section XIV) ROTS, ROTW, ROTG, and ROTM with 'API' Cross Over Mandrel or Packing Mandrel and BB Seal Unit according to the Nominal Size.
Rebco BB Circulating Bottom Sub-Assemblies for use in BR Landing Nipple are to be used with Lock Mandrels (See Section XIV) ROTZ, and ROTK with 'API' Cross Over Mandrel or Packing Mandrel and BB Seal Unit according to the Nominal Size.
BT Circulating Choke Bottom Sub-Assembly
Rebco BT Circulating Choke Bottom Sub-Assemblies for use in BF Landing Nipple are to be used with Lock Mandrels (See Section XIV) ROTW, with 'API' Cross Over Mandrel or Packing Mandrel and BB Seal Unit according to the Nominal Size.
Rebco Type BT Circulating Choke Bottom Sub-Assemblies for use in BR Landing Nipple are to be used with Lock Mandrels (See Section XIV) ROTZ, with 'API' Cross Over Mandrel or Packing Mandrel and BB Seal Unit according to the Nominal Size.
