We supply a range of accessories for hollorods, all made by Tenaris.
Specially designed to support a Flush or Near Flush external connection, the HolloRodTM nipple can withstand a larger amount of torque than standard sucker rod connections.
HOLLOROD/ API THREAD CROSSOVER
A crossover that allows standard API-threaded accessories to be attached to hollow rods.
HOLLOROD / HOLLOROD CROSSOVER
This other crossover allows different models of hollow rods to be connected between each other.
The injection swivel allows fluids to be injected into the well through the hollow rod string.
Installed either down-hole or at the wellhead, check valves are used to prevent production/ injection fluids from entering/returning into the hollow rod string. This improves safety at the rig.
POLISHED HOLLOW ROD
The polished hollow rod provides an effective seal between the environment and the production fluids at the uppermost section of the hollow rod string.
SLOTTED PUP JOINT
Along with a check valve, the slotted pup joint allows fluids to be injected into the tubing at varying depths. This is used to flush away sand, control corrosion, control paraffin deposition, reduce scale build-up or reduce heavy oil viscosity. The device also makes it possible for production fluids to be simultaneously lifted through both the inside of the hollow rod string and the tubing / rod string annulus.
