Hot Melt Three-Way, Hot-melt welding fittings
core definitions and characteristics
The core definitions and characteristics are as follows:
Youdaoplaceholder0 defines the core element
Material properties: Made from polyethylene (PE), it has corrosion resistance, light weight and high toughness.
Youdaoplaceholder0 Connection principle: By heating the end faces of the pipe and the fitting to a molten state, they are fused under pressure and then cooled to form a molecular-level sealed interface.
Youdaoplaceholder0 Function Positioning: Used for conveying liquids or gases (such as tap water, gas), to ensure system sealing and structural integrity.
Main classification and characteristics
They are divided into two categories based on structural differences:
Hot-melt socket tube
Youdaoplaceholder0 Applicable pipe diameter : Outer diameter ≤110mm (small diameter pipe).
Youdaoplaceholder0 Typical components : Socket elbows, tees, plugs and threaded fittings (such as internal thread unions).
Youdaoplaceholder0 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
Youdaoplaceholder0 Applicable pipe diameter : Outer diameter ≥75mm (for large-diameter pipes).
Typical components : butt joints, tees, flanges and plugs.
Youdaoplaceholder0 Connection method : Special butt welding machine heat the end of the tube, fuse under pressure and then cool.
Youdaoplaceholder0 Core advantage
Youdaoplaceholder0 Strong sealing property: Molecular fusion at the fusion interface eliminates the risk of leakage.
Youdaoplaceholder0 High durability: Resistant to chemical corrosion and has a service life of over 50 years.
Youdaoplaceholder0 Easy to construct: Low density (about 1/8 of steel pipe), no additional anti-corrosion treatment required.
application scenarios
