Long-sweep manifold fittings use a bend radius typically 2D or greater to reduce turbulence and pressure drop. Equal or reducing elbows, tees and crosses form high-pressure mud, cementing, fracturing and offshore drilling manifolds.
Technical features
Equal and reducing configurations
Long-sweep full-flow tee and cross
90-degree long-sweep elbow
Standard and special wall schedules
Forged AISI 4130 reference construction
Material strength matched to pressure class
Temperature derating reviewed above 121 °C
Typical applications
Mud standpipe manifolds
Fracturing, cementing and mud systems
Wellhead and tree flow connections
Offshore drilling-fluid circulation
Erosion-sensitive high-velocity lines
