90° pipe bend, Type 5: Long radius for maximum flow

When flow efficiency and wear protection are top priorities, a standard elbow is often not sufficient. The 90° pipe elbow, Type 5 (also known as Type 5D), is characterised by its particularly long radius. With r ≈ 2.5 times the external diameter, the bend is significantly more pronounced than that of a standard elbow. At FeNau GmbH, you can obtain these special fittings made from seamless steel in the as-rolled condition – the perfect solution for demanding pipework systems.

Type 5 vs. Type 3: What is the difference?

The difference lies in the geometry. Whilst a standard elbow (Type 3) redirects the fluid relatively abruptly (radius = 1.5 × diameter), the Type 5 pipe elbow guides the fluid gently round the bend (radius = 2.5 × diameter).

Lower pressure loss: The wide bend results in less turbulence. Pump capacity can often be reduced.
Less wear: In pipes conveying abrasive media (e.g. granules, sand, slurries), the long radius significantly reduces the impact on the pipe wall.
Easier cleaning: Pipes suitable for pigging benefit from the wide radius.

Ideal for industry, material handling and design

In addition to technical pipework (e.g. for compressed air or hydraulics), the long-radius steel bend is also often used for other purposes: in design and balustrade construction, the wide curve creates a completely different, very elegant look that stands out from standard designs. As we supply the bend as raw (untreated) steel, you have complete freedom in terms of further processing – whether welding, painting or galvanising.

Frequently asked questions about Type 5 arches (long radius)

When should I choose Type 5 rather than Type 3?

Opt for Type 5 if you need to maintain a high flow velocity without losing pressure, or if the material inside the pipe is abrasive (risk of abrasion). For purely structural applications (railings), it is a matter of the desired appearance (wide curve).

Are Type 5 bends standardised?

Yes, these products comply with DIN 2605 Part 2 and the current EN 10253 (Type 5D). Dimensional accuracy and wall thickness are precisely defined, making them ideal for professional plant engineering.

How much space does a 90° Type 5 bend require?

Allow for significantly more space than with the standard type. Rule of thumb: The overall length (centre to end) is 2.5 times the pipe diameter. A 42.4 mm bend therefore has a projection of over 100 mm (compared to approx. 60 mm for Type 3).
