BIG SIZE SPIRAL WELDED AND LONGITUDINAL STEEL TUBES (HFW, HFI, ERW,
SAWH, SAWL)
Our company deals with spiral and longitudinally welded steel tubes as well from stock and from fresh production with
favorable prices with different lenghts and qualitis. Our spiral and longitudinally welded tubes used mainly at the machinery,
building an energy sectors.
The outside diameter sortiment of the welded tubes is untill 4500 mm in case of spiral welded tubes and untill 2200 mm
in case of longitudinally welded tubes. In both welded tube typs there is a possibility to produce and adjust unique and
customised wall thickness, outside diameters different from the standard.
In case of steel qualitis the most common structural qualitis available such as the most specific boiler ones.

The advantage of steel tubes for precision applications is the high precision of their manufacturing, the good quality of their surface, and the guaranteed mechanical and technological properties. That is why the pipes are widely used in the machining industry and in the automotive industry. Welded pipes for precision applications are manufactured in the process of cold drawing.
