4″ FIG 206 Flow Iron Fittings: Tee, Crossover & Elbow Assemblies (2000 PSI CWP)
High-pressure fluid handling in European oilfields, well stimulation, and drilling mud manifold distribution requires durable connections that prevent leaks during continuous pulse pressure. Shanghai PME Industrial manufactures precision-engineered 4 Fig 206 flow iron fittings to provide reliable fluid routing across rugged operations.
Constructed from high-tensile heat-treated forged alloy steel, every 4 inch 2000 psi flow iron fitting incorporates a specialized replaceable elastomeric O-ring seal embedded in the male sub. This seal design provides primary pressure-tight isolation, protecting union threads from fluid corrosion and abrasive erosion while holding an operational rating of 2,000 PSI Cold Working Pressure (CWP) and a hydrostatic test rating of 3,000 PSI.
4″ FIG 206 Flow Iron Tee
Available in MxMxF and MxFxF configurations for flow splitting and merging.
4″ FIG 206 Crossover Union
Available in FxF, MxM, and MxF configurations for adaptable line transitions.
4″ FIG 206 Elbow Fitting
Heavy-wall 90° bends supplied in FxF, MxM, and MxF union connections.

Application & Performance Profile: Mud Circulation & Flow Control
Operational Challenge: High-pressure drilling fluid manifolds and test lines frequently experience seal degradation and thread stress under continuous pulsation, thermal expansion, and line misalignment. Standard rigid piping setups often lead to connection fatigue and persistent leakage during pressure cycles.
PME Flow Iron Integration: Integrating Shanghai PME Industrial’s 4″ FIG 206 flow iron fittings directly into surface circulation manifolds solves these routing and sealing challenges:
- 4″ FIG 206 Tees (MxMxF / MxFxF): Provide smooth, balanced fluid splitting and merging at high-pressure manifold junctions.
- 4″ FIG 206 Elbows (FxF / MxF): Deliver durable 90-degree directional changes while absorbing thermal and mechanical line stresses.
- 4″ FIG 206 Crossovers (MxM / FxF): Serve as versatile transition adapters between differing male/female terminal connections.
The Performance Result: The embedded elastomeric O-ring seal provides primary leak-tight isolation during cyclic pressures. Combined with rugged hammer union end connections, these fittings enable rapid field assembly and teardown, significantly reducing operational downtime and maintenance costs.
