FAQs
-
As the name suggests, seamless hollow sections have no weld seam and therefore no potential predetermined breaking point. This prevents faults or failure of the hollow section at the seam.
-
voestalpine Tubulars offers hollow sections in square and rectangular shapes. The portfolio currently includes square dimensions from 40 x 40 mm up to 170 x 170 mm and rectangular dimensions from 50 x 30 to 200 x 100 mm.
However, this is being continuously expanded and further developed.
-
Our seamless hollow sections are used in a wide variety of areas. These include structures such as support structure for large-scale and photovoltaic systems, hall and building constructions, agricultural equipment, mechanical engineering and the mobility sector.
-
The leading standard for hollow sections is DIN EN 10210-1, -2, -3 and ASTM A501/A501M, which defines the requirements for the pipe. The seamless hollow sections from voestalpine Tubulars fully comply with this standards.
-
With seamless hot-rolled hollow sections, the homogeneity of the material properties can be guaranteed across the entire cross-sectional area. Furthermore, a tighter corner radius can be produced while maintaining the same product properties.
-
The main special features are the homogeneous structure across the entire cross-sectional area and the tighter corner radius achieved through the seamless hot rolling process. In addition, our seamless hollow sections have no mechanical weak point due to the lack of a weld seam and can be used for a wide range of applications.
