Products Description

Connection Principle:

Copper wires inside fittings melt at 220±10°C, fusing HDPE interfaces under controlled voltage.

Types:

•Reducing Tee (e.g., DN160-125-160)

•90° Elbow (e.g., DN110-90°)

•Coupling (DN32-DN250)

Scope: DN20–DN630 pipes, pressure-rated up to 1.6MPa (SDR11).

Quality Control Process

CNAS Laboratory Validation:

Pre-fusion Check: Wire resistance (4.8Ω±0.1Ω) and surface smoothness (Ra≤0.1μm).

Post-fusion Test:

•Hydrostatic strength: 12.4MPa at 20°C/100h (no leakage)

•Peel test: Joint strength ≥95% of base material

Batch Sampling: Oxidation induction time ≥20min (200°C) for every 500 units.
