PE100 Black Large-Diameter Electrofusion Coupler DN450-630 | 4.0mm Manual Pin SDR11 | PN16 Water / 10 Bar Gas | Heavy-Duty Welded Jointing for Large Water, Gas & Mining Pipelines | ISO Certified

Product Description

This PE100 extra-large diameter electrofusion coupler (electrofusion sleeve) with 4.0mm manual pin is designed for joining large PE pipes from DN450 to DN630 in gas, water, wastewater, irrigation and mining applications. Manufactured from virgin PE100 black polyethylene.

Engineered for large-diameter transmission mains, these couplers provide fully welded, leak-free joints for high-capacity pipeline systems. The production quality, reliability and flexibility of electrofusion fittings give contractors the certainty needed for large-scale polyethylene pipe jointing.

For DN560 and DN630 sizes, a dual-shot (DS) welding procedure is required — two sequential electrofusion cycles. Rising pin fusion indicators allow easy visual monitoring throughout the process. Operating temperature range: -10°C to +40°C.

Typical Applications

• Large-diameter municipal water transmission mains
• High-capacity gas distribution and transmission networks
• Wastewater and sewage outfall / rising mains
• Large-scale agricultural irrigation main lines
• Mining slurry and dewatering pipelines
• Industrial process water and cooling systems

Key Features

• Manufactured using virgin PE100 black polyethylene for superior long-term performance
• Water PN16 / Gas 10 Bar rating (dependent on PE pipe welded and local pipeline pressure regulations)
• 4.0mm manual pin — compatible with standard electrofusion welding units
• SDR range 11–17, covering the most common large-diameter wall thicknesses
• Rising pin fusion indicators allow easy visual monitoring of the fusion process
• Manual welding parameters moulded directly into the fitting body
• Individually numbered for precise batch tracking and quality control
• Permanent batch number clearly marked for quality control
• Barcode and QR code enables full traceability back to raw materials
• Welding barcode compliant with ISO 13950; traceability barcode compliant with ISO 12176-4
• Dual-shot (DS) welding available for DN560 and DN630 — two controlled fusion cycles

Reference Numbers & Dimensions

Note: DS = Dual Shot, requiring two sequential electrofusion cycles. All stated technical specifications depend on the PE pipe welded to and local pipeline pressure regulations. Please contact us for detailed drawings and CAD models.
