Linde Engineering has been manufacturing spiral-welded aluminium pipes at its Schalchen plant since 1976. The Group has produced over 1000 km of spiral welded pipes over the decades, delivering outstanding results for customers such as Siemens, ABB and CGIT.
Linde’s spiral-welded aluminium pipes can be used for a wide range of applications, including cryogenic processes, gas-insulated switch gears and transmission lines, and process engineering (gas treatment plants).
The pipes are made from aluminium and a range of aluminium alloys. They can be up to 18 metres long, with diameters ranging from 273 to 1,200 mm and wall thicknesses from 4 to 10 mm. This flexible portfolio means that Linde spiral welded pipes can be tailored to any industrial requirements.
The pipes are manufactured using an optimized proprietary welding process that guarantees joint efficiency of V = 1.0. All materials are tested in line with the code requirements and individual customer specifications. In addition, our pipe surfaces are free of oil and grease, making them ideal for use with oxygen.
