Clamping tools and accessories.

Clamping systems.

High-quality pipe welding starts with the fixing of the pipe components. We offer a wide range of different clamping tools for this purpose:

Internal clamping device with two pneumatic cylinders
Hydraulic internal clamping device for thick-walled pipes
Manual stapling and forming device
Hydraulic stapling and forming device

Internal clamping device with two pneumatic cylinders.

The clamping systems specially developed by Westfalen bring enormous benefits for pipe production. The numerous advantages facilitate prefabrication both in the pipe workshop and on construction sites. Savings of up to 60 % are possible.

No stapling.
Optimum pre-alignment of the pipe parts thanks to separate clamping (double cylinder).
Gap-free pressing of the pipe parts to be welded together.
Automatic centring of the pipe fittings.
Minimises ovality tolerances.
No post-treatment of the workpieces (tarnish-free root).
Significantly reduced forming gas consumption (small forming gas chamber/no gas pre-flow time).
Flexible use as a mobile construction site tool or in pipe production.
Suitable for continuous use with water cooling.
Clamping range from DN 25 - DN 400 mm.

Hydraulic internal clamping device for thick-walled pipes.

For welding thick-walled pipes in pipeline construction.
Clamping, forming and welding in a single operation.
No tacking.
High force transmission, thus equalising ovalities up to 15 mm wall thickness.
Therefore safe use of mechanised orbital welding.
No post-treatment of the workpieces (tarnish-free root).
Clamping range from DN 150 - DN 400.

Manual stitching and forming device.

3 sets of jaws per diameter for flange/pipe or flange/elbow connection.
Simultaneous alignment and fixing of the components.
Precise tacking and welding device - with and without air gap.
Tarnish-free due to precise and uniform internal forming.
Due to design measures, only one set of jaws is initially clamped, making it easy to handle Scope of delivery with ISO or DIN jaws.
Complete in a case for nominal sizes: DN 25, 40, 50, 65, 80, 100 each with 3 sets of jaws and handles for DN 25, 40, 50/65 and 80/100.

Hydraulic stitching and forming device.

With the hydraulic tacking and forming device, both pipe/pipe and pipe/fitting connections can be tacked and also welded with low power.
Due to the high clamping force, only one piston is required for nominal diameters DN 40 - DN 200. Only a quick jaw change is required for adaptation.
Thanks to the small piston, this device can also be used for long pipes.
