Our Malleable Iron Electrophoretic 45° Elbows are engineered for high-performance fluid transmission, blending superior structural integrity with advanced surface protection. Designed specifically to reduce flow resistance and maximize durability, these fittings are the ideal choice for demanding industrial environments where precision and corrosion resistance are non-negotiable.
By integrating an optimized 1.5D curvature radius and a full-immersion epoxy electrophoretic coating, our 45° elbows significantly minimize pressure loss and eliminate turbulence. This professional-grade solution ensures long-term operational stability across chemical, marine, and HVAC systems, providing a seamless transition for corrosive media and high-pressure fluids.

A 45° elbow provides a smoother transition, which significantly reduces pressure loss (by up to 65%) and minimizes turbulence, improving the overall efficiency of the pumping system.
Electrophoresis provides 360° full immersion coverage, ensuring that even the interior surfaces are protected. This achieves a C5 corrosion rating, essential for marine and chemical environments.
The 1.5D optimized radius helps maintain a laminar flow, preventing the formation of eddies and turbulence that typically occur in tighter bends, thereby reducing wear on the pipe walls.
The standard working pressure is 4.0MPa (PN40). However, due to our reinforced wall thickness technology, the burst pressure is tested up to 7.2MPa for added safety.
Yes, these malleable iron fittings are designed to operate reliably in temperatures ranging from -30℃ to 130℃.
We recommend using a nylon-coated wrench during installation to prevent scratching the epoxy coating. Additionally, ensure the medium flow direction is consistent with the elbow direction.
