HDPE Butt Fusion Bend 11°
The HDPE Butt Fusion Bend 11° is a precision-engineered fitting designed to slightly redirect pipeline flow by 11 degrees. It is fabricated from PE100 high-density polyethylene, ensuring excellent chemical resistance, long-term durability, and strength. This bend is ideal for applications that require a minimal change in pipeline direction while maintaining a smooth and continuous flow. The butt fusion welding process ensures a strong, leak-proof joint, making it perfect for use in water distribution, gas transport, chemical processing, and industrial systems.
An HDPE Butt Fusion Bend 11° is a type of HDPE pipe fitting designed to change the direction of a pipeline by 11 degrees. It is joined to HDPE pipes using the butt fusion welding method, where the pipe and fitting ends are heated and fused together to create a permanent, leak-proof, and high-strength joint.

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.
