45° Spigot Elbow SDR 7.4 PN25 Butt Fusion PE100 Elbow for Fire Mains and Abrasive Duty Pipework

45° Spigot Elbow PE100 SDR 7.4 — Heavy-Duty Direction Change Butt Fusion Fitting

The PE100 45° spigot elbow (SDR 7.4) is the heavy-wall high-pressure direction change fitting of the butt fusion programme — rated Water PN25. Its gentle 45° sweep turns the pipeline with lower head loss and less turbulence than a 90° bend, while the thick SDR 7.4 wall delivers the strength demanded by fire hydrant mains, long-distance transmission lines and abrasive duty service.

Manufactured from virgin PE100 black polyethylene supplied by recognised polymer leaders such as Borealis and Ineos, our spigot elbows carry full batch traceability. The one-piece moulded construction produces a smooth bore with no seams, maximising flow and eliminating stress concentration points. Long spigot ends give the welder generous clamping and fusion space, while factory-chamfered ends follow DVS 2207 / ISO 21307 welding procedures.

The range covers d25mm to d315mm as standard stock, with d20 and d355–d500 produced on request. Each fitting is individually marked with size, SDR, standard and batch codes.

Typical Applications

• Fire hydrant and fire protection mains (underground water supply)
• High-pressure water transmission and trunk supply lines (PN25)
• Abrasive duty pipework — slurry, mining and sand handling lines
• Municipal water networks requiring gradual direction change
• Butt fusion PE100 systems where electrofusion is not available

Key Features & Benefits

• 45° gentle sweep — lower pressure loss and reduced turbulence vs 90° turns
• SDR 7.4 heavy wall — the thickest, strongest wall class in the PE100 programme
• PN25 rating — rated for high-pressure water and fire mains duty
• Moulded one-piece construction — smooth bore, no seams, no weak points
• Butt fusion jointing — full-strength PE-to-PE weld per DVS 2207 / ISO 21307
• Long spigot ends — generous clamping and fusion space for the welder
• Factory-chamfered ends — ready for immediate butt fusion on site
• Full traceability — batch-coded virgin PE100 (Borealis/Ineos grade)

Why Choose 45° Instead of 90°?

For fire hydrant mains and long transmission runs, a 45° elbow reduces the direction change stress and pressure loss compared with a 90° bend, extending pump range and protecting joints against surge. Where a gradual alignment change is possible, 45° fittings are the preferred choice of pipeline engineers.

Available Sizes — Moulded 45° Long Spigot Elbow, SDR 7.4 (PN25)

Note: sizes d20, d355, d400, d450 and d500 available on request. Z (centre-to-end) and L (total length over spigot ends) values per ISO 8085-3 for moulded long spigot 45° elbows — ask for the dimension sheet matched to your project. Contact us for CAD drawings.
