HDPE Electro Fusion Tape Shrink Sleeves Product Line for HDPE Structured Wall Spiral Pipe

Engineered by QINGDAO HUASHIDA PIPE-WELDING TECHNOLOGY CO., LTD
For leak-proof, life-long joints on HDPE structured-wall spiral pipes

1.Large-diameter HDPE structured-wall spiral pipes (ID 200-3500 mm) are the backbone of modern storm-water, drainage and marine-outfall systems. Yet their profiled outer wall makes conventional butt-fusion and electro-fusion couplers unreliable:
- uneven surface → poor heat transfer
- gap between profiles → cold zones & leakage paths
- field mis-alignment → long installation times & call-backs

Huashida's answer: a factory-integrated Electro-Fusion

TAPE SHRINK SLEEVE** that shrinks, melts and anchors itself to the pipe profile in one automatic cycle—creating a 100 % seal that lasts as long as the pipe itself.

2. What It Is A tri-layer, co-extruded "active sleeve":
1. Outer radiation-crosslinked PE sleeve – shrinks ≥ 30 % to hug the pipe profile
2. Middle layer of Ni-Cr wire mesh – delivers uniform, controllable fusion energy
3. Inner reactive E-fusion adhesive – melts & flows into pipe corrugations, forming a fusion-bonded, monolithic joint

Simply slide the pre-fabricated sleeve over the bell-spigot, connect the 4 mm plug, press START on the Huashida programmable junction box—15-25 minlater the joint is cooled, sealed and ready for back-filling.

✅ Fits every profile – ring, T-rib, hollow-square, ultra-rib, Krah ...
✅ DN 200-3500 mm – one production line, any diameter on request
✅ No sanding, no primer, no open flame – safest field install
✅ Tensile ≥ 18 MPa, peel ≥ 120 N/cm – exceeds ISO 21307 & DVS 2207
✅ Pressure-rated up to 0.5 MPa – perfect for non-pressure & low-pressure lines
✅ UV-stable, seawater-resistant, -40 °C to +60 °C** – designed for 50-year life
