Engineered for extreme durability, our Malleable Iron Electrophoretic Reducing Hoses provide a high-performance diameter reduction solution for complex piping systems. By combining high-strength malleable cast iron with a sophisticated triple-layer protection system, these fittings ensure seamless fluid transition while maintaining structural integrity in the most demanding industrial environments.
Our advanced electrophoretic coating technology redefines corrosion resistance, offering a uniform, 360° protective barrier that far exceeds traditional galvanizing standards. Designed for precision and reliability, these reducing hoses are the ideal choice for coastal engineering, chemical transport, and high-end commercial infrastructure where zero failure is the only acceptable standard.

Unlike galvanizing, electrophoresis uses an electric current to deposit an epoxy resin layer, ensuring 360° uniform coverage including internal threads and corners, providing 3x better salt spray resistance.
The working pressure is rated at 4.5MPa, with a certified burst pressure of ≥9MPa, ensuring a high safety factor for industrial applications.
Yes, they are designed for temperature shock resistance ranging from -30℃ to 130℃, cycling without cracking or coating delamination.
Our products are manufactured in strict accordance with GB/T 3287 and ISO 49 international standards for quality and dimension precision.
We recommend using matching protective gaskets, avoiding Teflon tape debris with special sealants, and utilizing a torque wrench for precise tightening.
Computational Fluid Dynamics (CFD) allows us to optimize the diameter transition curve, which reduces fluid turbulence and prevents premature erosion of the inner wall.
