HDPE Long Radius Elbow 90 Degree
A HDPE Long Radius Elbow 90° is a specially designed pipe fitting made from high-density polyethylene (HDPE), which is a durable, corrosion-resistant, and lightweight thermoplastic material, used to change the direction of fluid flow in a pipeline by 90 degrees, and its long radius design—typically 1.5 times the pipe diameter—helps to minimize friction, reduce turbulence, and lower stress on the piping system, making it ideal for applications in sewage, and various industrial fluid transport systems, and it can be easily connected to HDPE pipes through butt fusion or socket fusion methods, ensuring a leak-free and long-lasting joint.

Key Features Of HDPE Long Radius Elbow 90 Degree
- Material Strength: Made from high-density polyethylene (HDPE) offering excellent durability, flexibility, and corrosion resistance.
- Long Radius Design: The bend radius is typically 1.5 times the pipe diameter, reducing friction loss and stress on the pipeline.
- Smooth Flow: Ensures minimal turbulence and pressure drop due to gradual directional change.
- Leak-Proof Connections: Can be joined to HDPE pipes using butt fusion or socket fusion for strong, reliable joints.
- Chemical Resistance: Resistant to a wide range of chemicals, making it suitable for industrial and chemical applications.
- Lightweight: Easier to handle, transport, and install compared to metal elbows.
