HDPE Butt Fusion Bend 22°
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.

Benefits of Using HDPE Butt Fusion Bend 22°
Durability
The use of high-density polyethylene (HDPE) ensures that the fittings are resistant to harsh chemicals and can withstand demanding environments.
Chemical Resistance
HDPE is non-toxic and resistant to corrosion, making it suitable for potable water, sewage, and gas distribution.
Ease of Installation
The butt fusion method requires fewer mechanical parts and eliminates the need for threading or adhesives, making installation straightforward.
Longevity
The longevity of HDPE fittings significantly reduces maintenance and replacement costs, making them a cost-effective choice over traditional metal fittings.
Seamless Joints
The butt fusion process creates a seamless joint with strength equal to or greater than the pipe itself, ensuring leak-proof and durable connections.

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.
