HDPE100 Electrofusion Butt Fusion Equal Tee for HDPE100 Water Supply

Product Overview

Constructed from PE100 grade HDPE—certified under the latest EN 12201-1:2024 standard for pressure piping systems—this fused tee delivers exceptional durability in both buried and above-ground installations. Rated for 16 bar (232 psi) working pressure at 20°C, it outperforms traditional metal tees by eliminating corrosion risks and reducing lifecycle costs by up to 40% over a 50-year service life. The one-piece molded design ensures uniform wall thickness with ±0.2mm dimensional tolerances, providing consistent flow characteristics across pipe sizes from 63mm to 315mm OD. Its fusion-welded construction creates a homogenous bond that is actually stronger than the pipe itself, ensuring leak-free performance even under ground movement and thermal expansion .

Product Features

Homogenous Fusion Technology

Designed specifically for butt fusion and electrofusion installation methods, the tee forms molecular bonds that eliminate potential leak paths common in mechanical joints. Electrofusion models feature embedded resistance wires with pre-programmed welding parameters (190±5°C) that ensure consistent fusion quality across installations. The fusion zones are reinforced with 15% thicker walls to maintain full pressure rating at the critical branch junctions, verified through 10,000-hour pressure testing at 20°C .

Structural and Hydraulic Efficiency

The tee’s optimized 45° branch angle minimizes pressure loss to less than 5% at design flow rates, confirmed through computational fluid dynamics (CFD) analysis. Its smooth inner surface (Ra <0.008mm) prevents turbulence and sediment buildup, maintaining water quality in potable systems. The PE100 material exhibits exceptional creep resistance, retaining 90% of its strength after 50 years of continuous operation—critical for maintaining pressure integrity in long-term infrastructure projects .

Environmental Resistance

Formulated with 2.5% carbon black additive, the HDPE tee provides superior UV resistance for above-ground installations, preventing photo-oxidation and brittleness in direct sunlight. It is completely resistant to corrosion from chlorinated water, soil chemicals, and common disinfectants used in water treatment. The material remains flexible at temperatures as low as -40°C and stable up to 60°C, ensuring year-round performance in extreme climate conditions .

Applications

This versatile fused tee excels in critical water distribution scenarios:

• Municipal Water Mains: Creates branch connections in urban water distribution networks, linking mainlines to residential and commercial service lines.

• Industrial Facilities: Distributes process water in manufacturing plants, food processing facilities, and power generation stations with strict hygiene requirements.

• Commercial Buildings: Manages water flow in hotel, hospital, and campus plumbing systems requiring reliable branch connections.

• Water Treatment Plants: Connects filtration systems, storage tanks, and distribution lines in potable water treatment facilities .

FAQ

Why choose HDPE fused tees over metal alternatives?

HDPE fused tees eliminate corrosion risks that plague metal fittings, while their homogenous fusion creates permanent, leak-free joints that reduce maintenance costs by up to 40% over a 50-year service life .

What size range is available?

Standard sizes include 63mm, 90mm, 110mm, 160mm, 200mm, 250mm, and 315mm OD, with custom sizes available for specialized infrastructure projects requiring larger diameters.

Is it suitable for drinking water systems?

Yes. The PE100 grade HDPE meets NSF/ANSI 61 and EN 12201-1:2024 requirements for potable water contact, ensuring no leaching of harmful substances into drinking water .

How does it handle ground movement?

The flexible HDPE construction absorbs soil shifts and settlement with a deflection capability of up to 5° without compromising joint integrity, far exceeding the performance of rigid metal or concrete fittings.
