HDPE Fusion Welding Tape for 60-80mm Corrugated Pipe Joint Sealing

Polyethylene electro heating fusion tape is a widely used connecting pipe fitting, particularly in the field of anti-corrosion and directly buried pre-insulated pipe field joints. It is made from polyethylene sheets complexed with electro-fusion wire, suitable for jointing hollow wall corrugated/structured HDPE pipes, metal reinforced HDPE spirally corrugated pipes, and buried PUF pre-insulation pipes.

1.Welding Design for Corrugated Pipes
According to the corrugated process, the peak and valley width typically range from 60mm to 80mm, with the narrow tape welding the pipe joint along the cutting edges.

2.Air Tightness Consideration
Due to various restrictions, the airproof capability after the pipe joint is welded cannot be guaranteed.

3.Optimal Welding Method
The best welding method involves using a hand extruder to weld the cutting edges inside the pipe first, followed by using the narrow tape to weld from the outside.

Performance Characteristics:

Waterproof
Excellent waterproof performance.

Axial Force Resistance
Capable of withstanding axial forces initiated by axial movements of the pipe in the ground.

Radial Force and Bending Moment Resistance
Able to withstand radial forces and bending moments.

Temperature Resistance
Can endure temperature effects and variations.

Consistent Insulation Layer Thickness
Maintains the same thickness as the line pipe insulation layer.

Polyethylene electro heating fusion tape is widely used in:
• Oil and gas transportation
• Water treatment and supply networks
• Industrial piping systems
• Construction and infrastructure projects
