PE100 60 Degree Seamless Bend SDR 11 — Mid-Angle Mandrel-Bent HDPE Sweep for Water & Gas
The PE100 60° seamless bend (SDR 11) is a mid-angle mandrel-bent fitting engineered for the turns that fall between a 45° sweep and a 90° elbow. Dual-rated Water PN16 (1.6 MPa) and Gas 10 Bar, it is manufactured from solid PE100 pipe heat-bent over a mandrel — continuous wall, no mould parting line, no weld seam.
On mountain and hillside water transmission lines, the 60° angle lets the pipeline follow the natural slope without kinking; at reservoir and tank intakes it aligns the incoming pipe with the inlet nozzle. In gas distribution it provides a smooth angled transition around buildings, services and other underground obstructions without the sharp head loss of a moulded 90° elbow.
The long sweep radius (standard 3D, custom up to 10D) keeps flow velocity smooth — a particular benefit on long-distance water transmission lines where every metre of head loss counts.
Typical Applications
- Mountain and hillside water transmission mains following terrain slopes
- Reservoir, tank and clean-water basin inlet connections
- Gas distribution network angled transitions around buildings and utilities
- Water treatment plant piping and pump station header turns
- Cross-country pipelines negotiating moderate bends without excavation widening
Key Features & Benefits
- 60° mid-angle sweep — fills the gap between 45° and 90° turns, matching real-world pipeline geometry
- Dual-rated SDR 11 — Water PN16 and Gas 10 Bar in one fitting, no need to stock two SKUs
- Mandrel-bent seamless construction — continuous wall, no mould parting line, no weld seam
- Smooth bore — long sweep radius reduces head loss on long transmission lines
- No stress concentration — better fatigue life than moulded elbows under cyclic pressure
- Butt fusion ends — welds directly to SDR 11 PE100 pipe per DVS 2207
- Custom radius available — 3D standard, up to 10D on request for minimum head loss
Why 60° instead of two 45° elbows?
Two 45° elbows welded together create a sharp reverse-kink with two fusion joints and two pressure boundary points. A single 60° seamless bend is one continuous piece of PE — fewer welds, fewer potential leak paths, smoother flow, and faster installation on remote mountain or reservoir sites.
60° Seamless Bend SDR 11 — Size Range & Rating
The 60° seamless bend is available across the full SDR 11 range. d63–315mm is standard stock; d20–50mm and d355–500mm are produced to order.
Product Standards & Certifications
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 / ISO 4427-3 — PE fittings for water supply (PN16)
- EN 1555-3 / ISO 4437-3 — PE fittings for gas distribution (10 Bar)
- DVS 2207 / ISO 21307 — Butt fusion jointing procedures for PE pipes and fittings

Note: SDR 11 is the most universally certified PE100 wall class for both water and gas duty. Material certificates and test reports supplied on request.
Shipping & Delivery Information
60° seamless bends are long, swept pieces that ship as shaped cargo. We pack them with angle-form separators so the bend angle is protected in the container.
After-Sales Service & Warranty
We stand behind the quality of our spigot fittings. Our commitment doesn't end at delivery — we provide welding, radius selection and installation technical support for your PE100 water or gas pipeline project.
Frequently Asked Questions
Common questions about our 60° SDR 11 seamless bend
What is a 60 degree seamless bend used for?+
A 60 degree bend is a mid-angle sweep used where a 45° turn is too shallow and a 90° turn is too sharp — typical uses are hillside and mountain pipeline turns, reservoir and tank inlet connections, and gas distribution angled transitions.
Is SDR 11 rated for both water and gas?+
Yes — SDR 11 is dual rated: Water PN16 (1.6 MPa) and Gas 10 Bar. It is the most common PE100 wall class for both municipal water mains and gas distribution networks.
What makes a bend 'seamless'?+
A seamless bend is mandrel heat-bent from solid PE100 pipe rather than moulded. The wall is continuous with no parting line or weld seam, giving a smoother bore, lower head loss and fewer stress concentrations.
Which sizes are available?+
The 60° seamless bend is available from d20mm to d500mm, with d63-315mm in standard stock and larger sizes produced on request. Custom radius is available on request.
Can the 60° bend be butt-fused to standard PE100 pipe?+
Yes — both spigot ends are machined to the same outer diameter and wall tolerance as standard SDR 11 PE100 pipe, so they weld with a standard butt fusion machine per DVS 2207.
