Ductile iron elbow fitting is a crucial pipe fitting used to change the direction of pipelines in various piping systems. Made from ductile iron, which possesses excellent mechanical properties, this elbow offers high strength, toughness, and ductility, making it suitable for a wide range of applications where reliability and durability are essential. Whether in water supply and drainage systems, heating, ventilation, and air conditioning (HVAC) systems, or industrial pipelines, ductile iron elbows play an indispensable role in ensuring smooth fluid flow and pipeline layout flexibility.
| Parameter | Specification |
| Material | Ductile Iron (e.g., ASTM A536) |
| Nominal Diameter | DN25 - DN300 (customizable) |
| Angle | 90°, 45° (common types) |
| Pressure Rating | PN10 - PN25 |
| Surface Treatment | Galvanized, Epoxy Coated, etc. |
Compared with other materials, ductile iron provides a perfect balance between strength and ductility. It can withstand high pressure and external impacts without easily cracking or deforming. Additionally, ductile iron elbows have a long service life, reducing maintenance and replacement costs.
The production involves several steps. First, ductile iron is melted and poured into elbow molds using the sand casting process. After solidification, the cast elbows undergo heat treatment to enhance their mechanical properties. Then, they are machined to achieve precise dimensions, followed by surface treatment like galvanizing or epoxy coating to improve corrosion resistance. Finally, strict quality inspection is carried out to ensure each elbow meets the required standards. We offer comprehensive services including customized production according to customer drawings or specifications, technical consultation to help select the right product, and after-sales support to address any usage-related issues.
