HDPE Butt Fusion Equal Tee 45°
An HDPE Butt Fusion Equal Tee 45° is a type of high-density polyethylene (HDPE) pipe fitting designed to connect three pipes of the same diameter, where the branch outlet is positioned at a 45-degree angle to the main pipeline.It is installed using the butt fusion welding process, in which the ends of the pipes and the fitting are heated and fused together to form a strong, leak-proof, and permanent joint.
The HDPE Butt Fusion Equal Tee 45° is a specially designed pipe fitting that facilitates the connection of three pipes of equal diameter, where the branch outlet is set at a 45-degree angle to the main pipeline. Made from high-quality PE100 HDPE material, this tee provides excellent mechanical strength, chemical resistance, and durability. It is widely used in industrial, municipal, and piping systems to enable smooth flow transitions and reliable branch connections. The butt fusion welding technique ensures a strong, leak-proof, and permanent joint suitable for high-pressure applications.

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.
