SDR 7.4 PN25 Seamless Bend HDPE Angle Bend 11°-90° Multi-Angle Mandrel-Bent for High-Pressure Water Lines

The PE100 multi-angle seamless bend range (SDR 7.4) covers 11°, 22°, 30°, 45°, 60° and 90° mandrel-bent HDPE bends in one heavy-wall catalogue. Rated Water PN25 (2.5 MPa), this is the angle kit engineers reach for on high-pressure lines where precise offsets, alignment corrections and gradual direction changes are required.

Every angle starts as a solid PE100 pipe heated and bent over a mandrel — continuous wall, no mould parting line, no weld seam, smooth bore. The SDR 7.4 heavy wall gives the pressure margin needed for mining slurry, high-rise risers and industrial process duty.

Where a single 90° bend cannot dial in the exact offset, the 11°/22°/30° angles let the fitter make small, precise corrections — the 45°/60° angles handle mid-range turns, and the 90° closes the corner. Typical use cases are mining slurry and process water lines, high-rise riser offsets, industrial process piping, hydraulic pump lines and high-pressure water mains alignment correction.

• Mining slurry lines and mine process water distribution
• High-rise building riser offsets and mechanical room loops
• Industrial process piping in chemical, pulp and food plants
• Hydraulic pump stations and high-pressure water injection lines
• Pipeline alignment correction and gradual direction changes on HP mains

• Six angles in one range — 11°, 22°, 30°, 45°, 60°, 90° cover any offset or alignment need
• Heavy-wall SDR 7.4 — rated Water PN25 (2.5 MPa) for high-pressure duty
• Mandrel-bent seamless construction — continuous wall, no mould seam, no weld line
• Smooth bore — lower head loss and less turbulence on high-velocity lines
• Small angles for precision — 11° and 22° bends dial in exact offsets without over-turning
• Full wall thickness at bend — no thinning or ovalisation beyond PE100 tolerance
• Butt fusion ends — welds directly to PE100 pipe per DVS 2207

Field pipework rarely turns a neat 90°. Most installations need a small offset — 11° to bring a riser back into line, 22° to clear a beam, 30° to align with a pump flange. Carrying the full angle range in stock means the fitter never has to make a double-90° compromise or a field weld that could fail under PN25 pressure.

Note: sizes d20–500mm across all six angles; d63-315mm standard stock, d20-50 and d355-500mm to order. Custom angles (5°, 15°, 75° etc.) and custom radii (up to 10D) produced on request — send your offset drawing for quote.

All spigot fittings are manufactured from certified PE100 virgin material and tested against international piping system standards. Production is backed by ISO 9001 and ISO 29001 quality management systems.

• EN 12201-3 — Plastics piping systems for water supply — Polyethylene (PE) — Part 3: Fittings (PN25)
• ISO 4427-3 — Plastics piping systems for water supply — Polyethylene (PE) — Part 3: Fittings
• DVS 2207 / ISO 21307 — Butt fusion jointing procedures for PE pipes and fittings (heavy-wall parameters)
• ISO 9001 / ISO 29001 — Quality management for pipeline product manufacture

Note: SDR 7.4 is a high-pressure water-duty class only. For gas-rated seamless bends, see SDR 11 (10 Bar) and SDR 17 (6 Bar). Certificates on request.

SDR 7.4 is the heaviest wall class — bends weigh more per piece and ship as long-length cargo. Multi-angle kits may be consolidated per size to reduce freight.

We stand behind the quality of our spigot fittings. Our commitment doesn't end at delivery — we provide welding, angle selection and installation technical support for your high-pressure PE pipeline project.
