Pipes DIN 24151 (EN 1506) / Ducts DIN 24192 (EN 1505)

We manufacture pipes, pipe fittings and ventilation ducts for air handling systems.
We are happy to manufacture special sizes according to your specifications.

Applications

Welded pipelines are used in air handling systems (process air) for conveying air (including dust-laden) without the addition of aggressive vapors or wear-promoting solids. They are used in the areas of ventilation, extraction, dust removal, exhaust air cleaning or flue gas cleaning.

We are happy to assist with the planning/design of pipe systems and material selection. The material grade to be used, pipe length, wall thickness, requirements for welding technology/surface treatment etc. are generally based on the respective purpose of use and are to be agreed between buyer and supplier on an order-by-order basis.

You can order a selection from our pipe range directly in our shop.

Pipe Connection Variants

Connection with Welded Flanges

Flat or angle flanges are permanently welded to the pipe ends - standard from the back side. On request, the flanges can also be additionally welded from the inside.

Sealing Options

For sealing, we offer a sealing cord that is glued to the flange. In addition, we offer suitably perforated flat gaskets that cover the entire flange profile.

Application Area
  • For oil mist-laden air
  • For hot exhaust gases
  • For vertical or longer-running pipelines where tightness and stability are required.
Dimensions
  • Diameter 80 to 2000 mm
  • Wall thicknesses 1.5 to 5.0 mm

Connection with Loose Flanges Behind Bead

The pipe ends are beaded about 10 mm wide. The flanges remain rotatable so that the components can be aligned more easily during assembly.

Sealing Options

For sealing, we offer a sealing cord that is glued to the bead.

Application Area
  • For air lines or dry conveying media
Dimensions
  • Diameter 80 to 2000 mm
  • Wall thicknesses 1.5 to 5.0 mm
Bitte beachten Sie

The double-sided beading shortens the nominal length of the pipes by 20 mm. Example: A pipe with a nominal length of 3000 mm then has an installation length L of 2980 mm. When ordering fixed lengths, the exact installation dimension must be specified.


Connection with Clamping Rings

The pipe ends are beaded 6 mm wide. The connection is made by means of a clamping ring pulled over the beads of two pipe ends.

Sealing Options

For sealing, we offer a bead sealing ring that is pulled over a bead. The clamping ring is then tightened.

Application Area
  • For quick assembly of pipelines with small diameters. To avoid the risk of sagging, adequate support of the pipe components must be ensured.
Dimensions
  • Diameter 80 to 400 mm
  • Wall thickness 1.5 to 2.0 mm
Bitte beachten Sie

The double-sided beading shortens the nominal length of the pipes by 16 mm. Example: A pipe with a nominal length of 3000 mm then has an installation length L of 2984 mm. When ordering fixed lengths, the exact installation dimension must be specified.


Weld Connection

The pipe ends remain smooth and are butt-welded on site.

Application Area
  • Primarily for parts that need to be adapted on site.

Combination of Different Connection Types

We manufacture individual components according to your wishes, e.g., one pipe end with flange, the other pipe end smooth, etc.
