Stainless Steel Pipe Bends
APT Systems is your reliable partner for the production
of thin-walled pipe bends with large bending radii, especially
those used in pneumatic conveyors. Our products are coldbent
without wrinkles on state-of-the-art CNC mandrel bending
machines.
On request we can produce extension pipe bends according to
your specific requirements. Besides our standard range of stock
products in stainless steel, we also process aluminium.
Features and Benefits
- Patented liner provides unequalled flexibility and kink resistance
- Excellent chemical resistance
- Smooth bore for fast flow and easy clean
- Resistant to diffusion of liquids and gases.

Aluminium Pipe Bends
Aluminium pipe bends are curved sections of aluminium piping used to change the direction of flow in a system. Lightweight, corrosion-resistant, and durable, they are ideal for routing air, gas, or fluids smoothly with minimal pressure loss, especially in pneumatic and industrial applications.
Features and Benefits
- DIN EN 573-3, 755-1, / -2 / -9
- Alloy: AlMgSi 0.5 F22
- Pipe outer diameter: 38.0 – 100.0 x 2.0 mm
- Wall thickness: 1.5mm/2.0mm or thicker
- Radius: 250 / 300 / 500 / 800 / 1000mm
- Wrinkle-free, no initial bumps
- Extremely low ovality
- Visually aesthetic surface
- Straight ends on both sides.
Glass Bends
For conveying abrasive media or for high flow rates,
we can supply you with glass pipe bends made from
3.3 borosilicate glass with a copper grounding strip.
With this glass pipe bends you could achieve the best
service life with respect to applications with glass fibre plastic granules.
These bends have a service life at least 10 times longer than stainless steel bends.
- Made of borosilicate glass 3.3
- Straight ends on both sides
- Copper grounding strip attached at the outer radius.
- NEW – On Request: Glass pipe bends encased in plastic.
High Wear Resistant Bends
We can supply you with highly wear resistant stainless steel pipe bends which have a service life 10 to 20 times longer than that of standard stainless steel pipe bends. This high degree of wear protection is required, for example, for conveying fibreglass-reinforced plastic granules or similarly abrasive media.
Features and Benefits
- Diameters from 38.0 to 168.3 mm
- Wall thickness from 1.5 mm to 2.0 mm
- Radius: 75 / 100 / 150 / 250 / 300 / 500 / 800 / 1000 mm
- For highly abrasive products
- Easy installation
- No stepped pipe couplings and no flange connections required.
