Our premium Malleable Iron Pipe Fittings featuring advanced electrophoretic coating are engineered for high-performance fluid distribution in the most demanding environments. By combining the structural resilience of malleable cast iron with a precision-engineered CFD-optimized flow design, these fittings significantly reduce eddy currents and pressure loss, ensuring maximum operational efficiency for industrial piping systems.
To combat extreme corrosion, we implement a rigorous 360° full-immersion electrophoresis process, creating a seamless 40-50μm epoxy resin barrier. Finished with a UV-resistant polyurethane transparent topcoat, these fittings provide an unparalleled shield against salt spray and chemical erosion, making them the ideal choice for marine engineering, chemical processing, and coastal infrastructure.

| Total Cost of Ownership | Higher (Due to Downtime) | Lower (Optimized Longevity) |
Electrophoresis provides 360° full-immersion coverage, eliminating the "dead angles" common in galvanizing. It offers superior salt spray resistance (≥1200h) and a more uniform thickness (40-50μm), ensuring better protection for complex shapes.
Computational Fluid Dynamics (CFD) was used to optimize the flow splitter and branch angles (precisely 45°), which reduces eddy currents and lowers pressure loss by 35%, increasing system energy efficiency.
Yes, they are specifically designed for marine engineering. The combination of epoxy resin and a polyurethane transparent topcoat provides high resistance to seawater corrosion and UV aging.
We recommend using a torque wrench for diagonal tightening and installing pipe supports within 30cm downstream of the branch. A pressure test at 1.5x working pressure should be conducted 24 hours post-installation.
Every piece undergoes 100% penetrant testing for casting defects, 6.0MPa water pressure testing for 5 minutes, and multi-point coating thickness verification at 16 different points.
For main pipe reductions, we recommend our "Reducing Tee" series. For high-pressure specific needs, our "Thickened Series Tee" is the optimal choice to ensure structural safety.
