Hot Melt Three-Way Welding Fittings - Durable PE Pipe Connectors from China Suppliers and Factory
Core Definitions and Characteristics
The core definitions and characteristics are as follows:
Main Classification and Characteristics
They are divided into two categories based on structural differences:
Hot-melt Socket Tube
- Applicable pipe diameter: Outer diameter ≤110mm (small diameter pipe).
- Typical components: Socket elbows, tees, plugs and threaded fittings (such as internal thread unions).
- Connection method: The pipe is inserted into the fusion joint of the fitting and heated and fused by hand with a hot fuse.
Hot-melt Butt Fitting
- Applicable pipe diameter: Outer diameter ≥75mm (for large-diameter pipes).
- Typical components: Butt joints, tees, flanges and plugs.
- Connection method: Special butt welding machine heat the end of the tube, fuse under pressure and then cool.
Core Advantages
Application Scenarios
Typical application scenarios:
Municipal water supply, fire protection pipe networks and drainage systems.
Frequently Asked Questions
What materials are these pipes and fittings made from?
They are made from high-quality Polyethylene (PE), which provides excellent corrosion resistance, a lightweight profile, and high toughness.
How does the hot-melt connection principle work?
The connection is created by heating the end faces of the pipe and the fitting to a molten state. They are then fused together under pressure and cooled to form a highly secure, molecular-level sealed interface.
What is the difference between hot-melt socket and butt fittings?
Hot-melt socket tubes are typically used for smaller pipe diameters (outer diameter ≤110mm) and fused by hand. Hot-melt butt fittings are designed for larger pipe diameters (outer diameter ≥75mm) and require a special butt welding machine.
What are the main advantages of using these fittings?
The core advantages include strong sealing that eliminates leakage risks, high durability with a service life of over 50 years, and easy construction due to their low density (about 1/8 of steel pipe) and no need for anti-corrosion treatments.
Where are these systems typically applied?
They are widely used in municipal water supply systems, fire protection pipe networks, and municipal or commercial drainage systems.
What is the primary function of these connections?
They are designed for conveying liquids or gases (such as tap water and gas) while ensuring absolute system sealing and structural integrity.
