Pipes HFW/HFI

HFI and HFW pipes are made using longitudinal welding with high frequency currents HFI (High Frequency Induction). The basic offer includes pipes made of normalized (N) and thermomechanically rolled (M) steel.
For specific projects, we can also provide pipes made of steel:
  •  special
  •  qualitative
  •  unalloyed
  •  low alloyed
  •  calmed down

Pipes are subjected to non-destructive testing, i.e. they are tested by ultrasounds or eddy currents. The basic tests also include the tightness test. The range of pipe diameters we offer covers the DN 200 - DN 500 range. The offered goods come from producers from the European Union. The aforementioned manufacturers operate in accordance with the implemented ISO 9001 quality management system. Our goods meet the requirements of the PED 2014/68 / EU pressure directive, have a construction mark and other approvals required on the Polish market.

  •  PN-EN ISO 3183
  •  PN-EN 10217-5
  •  PN-EN 10217-3
  •  PN-EN 10217-2
