Butt Fusion Drainage Reducing Tee
Butt Fusion Sealing, Leak-Free Drainage: Exclusive butt fusion design, welds tightly with drainage pipes of different calibers. Interface strength's higher than the pipe itself, sealing's reliable-no leaks or odor return, I don't think. Perfect for drainage branching scenarios.
Virgin Raw Material, Corrosion Resistant: Uses new virgin PE100 HDPE, no recycled materials. Dense texture, resists acid, alkali and sewage corrosion. No heavy metal leaching, not easy to scale-fits domestic sewage, industrial wastewater discharge.
Smooth Inner Wall, Unobstructed Flow: CNC integral molding, inner wall's mirror-smooth, no burrs or dead corners. Water flow resistance is low, won't collect debris or clog pipes. Ensures smooth drainage, cuts down dredging times.
Reduced Diameter Design, Multi-Spec Adaptable: Designed for different-caliber drainage branching-main port and branch port calibers differ, fits DN50-DN2000 full-caliber combinations. Works with PN4-PN16 pressure grades, strong compatibility.
Durable & Low Maintenance: Runs stable from -40℃ to 60℃, UV resistant, anti-aging. Handles soil settlement, not easy to break or deform. Lasts over 50 years, almost no later maintenance costs.
Strict Inspection, Export-Qualified: Passes three strict checks-water pressure sealing, inner wall smoothness, appearance. Comes with test report, supports CE and SGS. Quality traceable, suitable for export and high-end projects.

Product Advantages
This is our Butt Fusion Drainage Reducing Tee, a core accessory for HDPE drainage pipe networks. It's specially designed for drainage branching with different calibers-splits large-caliber main pipe flow into small-caliber branches, or combines small-caliber flows into a main pipe. Widely used in municipal drainage, residential communities, industrial parks, sewage treatment plants and other drainage projects.
We adopt new virgin PE100 HDPE raw material, no recycled stuff, which ensures good corrosion resistance from the source. Meets GB/T13663-2018 and ISO 4427 standards, resists acid, alkali and sewage erosion, no heavy metal precipitation. It's not easy to scale or breed bacteria, safe for various drainage media.
CNC integral molding, no splicing gaps. The inner wall is mirror-smooth, which minimizes water flow resistance and avoids clogging caused by debris accumulation. The exclusive butt fusion design makes the interface stronger than the pipe itself, completely solving common problems like drainage leakage and odor return.
It fits DN50-DN2000 different-caliber HDPE drainage pipes, with flexible caliber combinations. The butt fusion process is easy to operate-ordinary workers can master it after simple training, no extra sealing accessories needed. Light weight, easy to carry and install, greatly saving construction time and costs.
Every product undergoes strict quality inspection, unqualified products are prohibited from leaving the factory. It comes with an exclusive test report, quality is fully traceable. Supports CE and SGS certifications, meeting the requirements of foreign trade export and high-end drainage projects.
We provide bulk customization services-can customize different main/branch caliber combinations and pressure grades according to your project needs. Also offer professional CAD drawings and butt fusion construction guidance. Overseas customers can enjoy FOB/CIF port delivery and one-on-one follow-up to solve installation and transportation problems.
