Boiler construction

Best quality steel for boilers and apparatus

Flender quality steel pipes are employed in numerous applications relating to the construction of boilers and apparatus and stand for consistently high quality. We specialise in pipes from 33.7 mm with seam annealing. In comparison to seamless pipes, they have lower tolerances and more evenness in the internal and external surfaces of the pipe.

We keep a variety of material goods and wall-thicknesses in stock for our customers and also convince with a needs-based production process and flexible delivery times.
