Cost-Effective PE100 Electrofusion Coupler DN450-630 SDR17 | PN10 Water / 6 Bar Gas | 4.0mm Manual Pin, Lightweight Welded Joints for Irrigation, Wastewater & Low-Pressure Water Mains

Product Description

This PE100 large-diameter electrofusion coupler with 4.0mm manual pin is designed for joining large PE pipes from DN450 to DN630 in gas, water, wastewater, irrigation and mining applications. The SDR17-26 thin-wall design offers a lighter, more cost-effective solution for lower-pressure large pipeline systems.

Manufactured from virgin PE100 black polyethylene with water rating PN10 and gas rating 6 Bar. The thinner wall reduces fitting weight, material cost and handling effort compared to SDR11 versions — ideal for irrigation, wastewater outfall, and low-pressure water transmission mains.

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

Typical Applications

• Large-scale agricultural irrigation main lines
• Wastewater and sewage outfall / rising mains (low pressure)
• Low-pressure water transmission and distribution networks
• Non-critical gas distribution systems
• Mining slurry and dewatering pipelines (low pressure)
• Industrial process water and cooling systems

Key Features

• Manufactured using virgin PE100 black polyethylene for long-term performance
• Water PN10 / Gas 6 Bar rating — optimized for lower-pressure large pipelines
• 4.0mm manual pin — compatible with standard electrofusion welding units
• SDR range 17–26, covering thin-wall large-diameter pipe series
• Lightweight design — easier handling, lower freight cost than SDR11 equivalents
• Rising pin fusion indicators for 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

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. This SDR17 version is lighter and more economical than the SDR11 (PN16) version — please select the correct pressure rating for your project.
