HDPE Butt Fusion Elbow 90°
An HDPE Butt Fusion Elbow 90° is a pipe fitting made from High-Density Polyethylene (HDPE) that is used to change the direction of a pipeline by 90 degrees. It is connected to HDPE pipes using the butt fusion welding process, where the ends of the pipe and the elbow are heated and fused together to form a strong, permanent, and leak-proof joint.It is a 90-degree angled pipe connector that helps change the flow direction sharply while maintaining a strong and leak-proof connection.
The HDPE Butt Fusion Elbow 90° is a high-performance pipe fitting designed to create a smooth 90-degree change in direction within HDPE piping systems. Manufactured from PE100 high-density polyethylene, this elbow offers excellent resistance to corrosion, abrasion, and chemicals, making it ideal for use in water supply, gas distribution, wastewater management, and industrial applications. The butt fusion welding method ensures a strong, leak-proof joint with the host pipe, delivering long-term reliability and durability.

HDPE Electro Fusion Fittings
Electrofusion fittings are specialized HDPE components designed with embedded electric heating elements that, when energized, melt and fuse the fitting to the pipe surface. This technique provides a secure, leak-proof, and durable joint, making it ideal for high-pressure and critical pipeline applications. Electrofusion is especially preferred when working in confined spaces, where using large butt fusion equipment is impractical.
HDPE Butt Fusion Fittings
Butt fusion fittings are one of the most reliable and widely used types of HDPE pipe fittings. These fittings are joined using a butt fusion welding process, which involves heating the ends of both the pipe and the fitting to a precise temperature (typically around 200–220°C), then pressing them together under controlled pressure until they fuse into a single continuous piece. This results in a permanent, seamless, and high-integrity joint.
