The Annular Manifold is a high-performance fluid conveyance system specifically engineered for the demanding environments of oilfield operations. Designed to handle high-voltage discharge pipelines, coil pipelines, well test lines, and cementing slurry pipelines, this system ensures the safe and efficient transport of fluids under extreme high-pressure conditions. Its modular architecture, consisting of precision-engineered elbows and straight pipe assemblies, allows for rapid deployment and seamless integration into existing rig setups.
Engineered for versatility and durability, the Annular Manifold is available in short radius, long radius, and live loss configurations to meet diverse site requirements. With a working pressure range spanning from 35 MPa up to 140 MPa (5,000 psi to 20,000 psi), it provides unmatched reliability in high-stress environments. The system’s inherent flexibility, vibration resistance, and high-flow capacity make it an essential component for maintaining operational integrity during critical drilling and completion phases.
