The Saptora Rotary Joint is robustly engineered to handle the suspended loads encountered in decoking operations. It performs two primary functions:
Water Transfer: Directs high-pressure water from the decoking hose into the rotating drill stem while maintaining a leak-proof seal.
Rotational Drive: Enables rotation of the drill stem and cutting tool assembly via a mounted driver, ensuring smooth and controlled cutting operations.
Flange sizes: 125 mm (5 in) 250 PN / 400 PN with compact connections matching the drill stem
Drive options: Air piston, electric-over-air, hydraulic, or electric motor with VFD
Dual-seal design: Standard dual seal provides three-year design life, with a secondary seal for six additional months of maintenance planning
Corrosion-resistant construction: Integrally cast, single-piece gooseneck and support cage eliminates welds
Upgrade Options for Legacy Rotary Joints:
Convert packing to dual seal
Change vertical air motor to horizontal motor with right-angle gear
Upgrade Unibolt coupling to direct-connect RTJ flange with drill stem
Convert to integral cast single-piece gooseneck and support cage
Add rotary joint stiffeners to the bonnet
Upgrade to heavy-duty bearings for extended service life
