High frequency welded – induction steel pipes
HFW / HFI / ERW

Pipes are manufactured according to the requirements of the following standards:

  • Council Directive CPR 305/2011,
  • Council Directive 2014/68/UE,
  • PN-EN ISO 3183,
  • PN-EN 10219-1/2,
  • API Spec 5L,
  • ASTM A53,
  • PN-EN 10217-1,
  • PN-EN 10217-2,
  • PN-EN 10217-3,
  • PN-EN 10224.

 

Pipes are manufactured in diameter range from 114,3 mm to 406,4 mm, in production lengths from 6 m to 18 m. Pipes are supplied with plain or bevelled ends, after hydrostatic test and automatic non-destructive ultrasonic or eddy current tests.

During production process the heat treatment is performed to eliminate stresses generated in the seam as well as to guarantee both homogenous steel structure and higher strength properties.
Depending on the required mechanical and technological properties or application, the pipes are produced from the following steel grades:

  • unalloyed and low-alloyed,
  • killed,
  • quality,
  • special.

Upon the customer’s needs pipes are supplied as: bare – without protection coating, or with external three-layer polyethylene (PE) or polypropylene (PP) anticorrosion coatings and with internal either cement or epoxy lining. Against agreement pipes may be supplied with other anticorrosion protection e.g. galvanized pipes.

High frequency welded (HFW) pipes manufactured by “FERRUM” S.A. can be successfully used to produce steel fittings including tees, reducers, elbows and bends. Fittings are made by either cold or hot bending process depending on the strength parameters of steel grade as well as the diameter and wall thickness.

Application of welded pipes demonstrates the highest level of excellence in microtunneling, most modern “digging” technique used to construct small tunnels. Completing the microtunneling by application of steel welded pipes provides both minimum im- pact on environment and slight interference with ecological land management.

In 1999 the most modern production line of high frequency welded (HFW) steel pipes and structural hollow sections was commenced into operation. The line was designed by the German enterprise SMS Meer and has an annual production capacity of 120 000 Mg for the specified production mix.
