Ductile Iron & Malleable Iron Pipe Fittings – Shell Mold Cast Tee, Elbow, Coupling, and Square Connector

We offer a comprehensive range of high-strength pipe fittings, including tees, elbows, couplings, reducers, and square connectors, all manufactured using advanced shell mold casting technology from premium malleable iron (KTH350-10) or ductile iron (QT500-7) materials. These fittings are widely used in construction scaffolding, gas pipeline systems, industrial structures, and water supply networks where durability, corrosion resistance, and precise fit are critical.

Our products feature smooth internal surfaces and uniform wall thickness, ensuring minimal flow resistance and long-term performance under pressure. The hot-dip galvanized coating (≥85g/m²) provides excellent protection against rust and oxidation, making them ideal for outdoor and harsh environments such as coastal areas or chemical plants.

The shell molding process allows us to produce complex geometries with high dimensional accuracy, tight tolerances, and minimal porosity—ensuring reliable sealing and structural integrity. Each fitting is inspected for defects, and we provide full documentation including Material Test Reports (MTR) and spectrographic analysis upon request.

• Superior strength: Ductile iron offers tensile strength ≥500 MPa and elongation ≥7%, while malleable iron provides excellent impact resistance.
• Corrosion-resistant: Zinc-coated surface extends service life by 3–5 times compared to bare iron.
• Versatile design: Available in various sizes (DN15–DN100), threads (NPT/BSP), and configurations (straight, angled, multi-port).
• Customizable: We support OEM/ODM services—send your drawing or sample for tailored solutions.

Whether you need standard AGA-compliant fittings for gas lines or heavy-duty connectors for scaffolding systems, our one-stop foundry solution ensures fast delivery, competitive pricing, and consistent quality.
