HDPE Butt Fusion Equal Tee 90°
An HDPE Butt Fusion Equal Tee 90° is a type of high-density polyethylene (HDPE) pipe fitting used to connect three pipes of the same diameter, where the branch outlet is positioned at a 90-degree angle to the main pipeline. It is joined using the butt fusion welding process, in which the pipe ends and the fitting are heated and fused together to form a strong, permanent, and leak-proof joint.
The HDPE Butt Fusion Equal Tee 90° is a crucial pipe fitting designed to connect three pipes of equal diameter at right angles, facilitating a 90-degree branch in the piping system. Manufactured from premium PE100 high-density polyethylene, this fitting delivers outstanding strength, corrosion resistance, and long service life. The tee is fabricated for use in demanding industrial, municipal applications where reliability and leak-free performance are essential. Joining is accomplished through butt fusion welding, ensuring a seamless, robust connection capable of withstanding high pressure and environmental stresses.

Types of HDPE Butt Fusion Equal Tee 90°
1. Standard Equal Tee
This is the most commonly used type where all three ends have the same diameter. It is used for uniform flow distribution in pipelines.
2. SDR-Based Equal Tee
These tees are classified based on SDR (Standard Dimension Ratio) such as SDR 11, SDR 13.6, SDR 17, etc. The SDR determines the wall thickness and pressure capacity of the fitting.
3. Pressure-Rated Equal Tee
Designed for different pressure classes like PN6, PN10, PN16, etc. These tees are selected based on the operating pressure of the pipeline system.
4. Long Spigot Equal Tee
This type has extended ends (spigots) for better butt fusion welding, ensuring stronger and more reliable joints.
5. Short Spigot Equal Tee
These have shorter ends compared to long spigot types and are used where space is limited.
6. Reinforced Equal Tee
Manufactured with extra material thickness at the junction to handle higher stress and pressure, commonly used in critical industrial applications.
7. Molded Equal Tee
Made using injection molding techniques, ensuring uniform structure and smooth internal surface. Suitable for small to medium diameter pipelines.
8. Fabricated Equal Tee
Created by welding sections of HDPE pipe together. These are typically used for large diameter pipelines and custom 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.
