Malleable iron pipe fittings with electrophoretic coating

Technical Highlights

Fluid Optimization Design

The flow splitter is optimized using CFD simulation to reduce eddy current generation.

The branch pipe connection angle is precisely controlled at 45°, reducing pressure loss by 35%.

The internal cavity is mechanically polished, with a roughness Ra≤6.3μm.

Full Protective Coating System

360° full-immersion electrophoresis process, eliminating any coating dead angles.

40-50μm epoxy resin electrophoretic layer, salt spray resistance ≥1200 hours.

Surface polyurethane transparent topcoat, UV resistant and anti-aging.

Installation specifications: 

① Before installation, confirm that the medium flow direction is consistent with the tee direction.

② Use a torque wrench to tighten gradually in a diagonal sequence.

③ It is recommended to add pipe support within 30cm downstream of the branch pipe.

④ Conduct a pressure test (1.5 times the working pressure) 24 hours after installation.

Quality Assurance: 100% penetrant testing of castings.

Multi-point measurement of electrophoretic coating thickness (≥16 points per piece).

6.0MPa water pressure test, holding pressure for 5 minutes.

Full inspection of dimensional accuracy, tolerance controlled within ±0.2mm.
