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.
