PE Hot Melt Equal Tee

The PE Hot Melt Equal Tee is a high-performance branch connection fitting designed for polyethylene piping systems. Manufactured from premium-grade HDPE using PE80 or PE100 virgin material, the fitting is produced through advanced injection molding and hot melt forming technology to ensure consistent quality and long-term reliability.

Designed with a three-way equal-diameter structure, all outlets feature the same pipe size, allowing efficient branch distribution and flow diversion within PE pipeline systems. The streamlined internal flow path and smooth inner surface help reduce pressure loss and improve fluid transmission efficiency.

This PE Hot Melt Equal Tee is widely used in PE water supply systems, gas distribution networks, municipal drainage projects, agricultural irrigation, and industrial fluid transport applications.

The product complies with major international and domestic standards including:

GB/T 15558
GB/T 13663
ISO 4427
ISO 4437

Installation is completed through hot melt butt fusion or socket fusion welding, where the pipe and fitting are heated and fused into a seamless, integrated connection for reliable long-term performance.

Product Features & Benefits

Strong Fusion Connection with Excellent Sealing

The hot melt fusion process creates a fully integrated joint between the fitting and the pipe. Once welded, the connection achieves the same structural strength as the pipe itself, effectively eliminating leakage risks commonly associated with traditional mechanical joints.

The integrated structure withstands:

Temperature fluctuations
Water hammer impact
Ground settlement stress
External vibration and pressure changes

This ensures stable and leak-free pipeline operation over extended service life.

Outstanding Mechanical Performance

High Impact & Deformation Resistance

The fitting offers excellent toughness and flexibility, making it resistant to cracking, deformation, and external impact under demanding installation environments.

Stable Pressure Resistance

Suitable for various pressure-rated pipeline systems, with reliable performance under both low and elevated temperature conditions.

Long Service Life

With proper installation and operating conditions, the service life can exceed 50 years, significantly reducing maintenance and replacement costs.

Excellent Corrosion & Weather Resistance

Made from chemically stable polyethylene material, the fitting is resistant to:

Acids and alkalis
Salts and wastewater
Soil corrosion
UV exposure and environmental aging

Unlike metal fittings, it will not rust, scale, or corrode, making it ideal for buried pipelines, outdoor installations, and chemically demanding applications.

Hygienic & Environmentally Friendly

The material contains no heavy metal stabilizers and is safe for potable water systems. The smooth inner wall prevents bacterial growth and scaling, ensuring clean and hygienic fluid transport.

Additional environmental advantages include:

Recyclable PE material
No construction waste during welding
Non-toxic and odorless composition
Compliance with drinking water safety standards

Lightweight & Cost-Efficient Installation

Compared with traditional metal fittings, the PE Hot Melt Equal Tee is lightweight and easy to transport, reducing labor and installation costs.

Additional advantages include:

Simple hot melt welding process
No complicated accessories required
Faster installation speed
Minimal long-term maintenance

This results in lower overall project costs and improved installation efficiency.

Smooth Flow Performance

The fitting features a smooth internal surface with low friction resistance, helping improve overall pipeline flow capacity while minimizing turbulence and pressure loss.

The equal-diameter tee design ensures balanced flow distribution and stable media transport throughout the piping system.
