SDR 17 Light-Wall 90 Degree Seamless Bend Mandrel-Bent HDPE Bend for Agricultural Irrigation

The PE100 90° seamless bend (SDR 17) pairs the smooth, continuous-wall mandrel-bend construction with the lighter SDR 17 wall — rated Water PN10 and Gas 6 Bar. It is the cost-effective seamless bend for agricultural and rural loops where heavy-wall PN16 is over-spec.

Like the SDR 11 version, it starts as a solid PE100 pipe heated and bent over a mandrel — no mould parting line, no weld seam, smooth bore. The lighter wall lowers material weight and cost, which matters on long snake runs across farms and greenhouse bays where dozens of bends add up.

Typical use cases are agricultural snake runs weaving around fields and crops, greenhouse heating and circulation loops, rural irrigation circuits, farm obstacle avoidance and low-pressure gravity loop pipework. Sizes cover d20mm to d500mm, with d63-315mm held as standard stock.

• Agricultural snake runs across fields, orchards and crop rows
• Greenhouse heating loops and warm-water circulation circuits
• Rural irrigation main circuits and pivot feed lines
• Farm obstacle avoidance around sheds, tanks and paddock fences
• Low-pressure gravity loop pipework and stock yard water rings

• Light-wall SDR 17 — lower weight and cost per bend for long loop runs
• Mandrel-bent seamless construction — continuous wall, no mould parting line, no weld seam
• Smooth bore — lower head loss, important on long irrigation circuits
• Custom radius — 1.5D to 5D standard, up to 10D on request
• Water PN10 / Gas 6 Bar — dual certified per EN 12201-3 / EN 1555-3
• Full wall thickness at bend — no thinning or ovalisation beyond PE100 tolerance
• Butt fusion ends — welds directly to PE100 pipe per DVS 2207

A 100-metre irrigation loop can use dozens of bends. Specifying SDR 17 (rather than SDR 11) on a low-pressure PN10 circuit cuts material weight and cost per bend by roughly a third — without compromising the smooth, leak-free mandrel-bend bore.

Note: sizes d20–50 and d355–500 available to order. Custom radius (up to 10D), custom angle (30°/45°/60° etc.) and special CLR produced on request. Send your loop 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.

Note: SDR 17 seamless bends are rated Water PN10 / Gas 6 Bar. Custom radii beyond 5D produced to project specification. Certificates on request.

SDR 17 seamless bends are lighter than SDR 11 — more pieces per carton and lower freight cost, which matters on bulk agricultural and greenhouse loop orders.
