  • Line pipes with high temperature services

    We supply the pipes that are suitable for bending and are used for the constructions of plants and equipment subject to high temperatures and pressures. The seamless pipes, hot rolled or cold drawn/cold finished with heat treatment.

    The ASTM A335/ASME SA335 and  EN 10216-2 norms require heat treatment also for the hot rolled pipes. The welded pipes are manufactured according to EN 10217-2. Supply of pipes suitable for high temperatures are according to;

    • ASTM A 106 / ASME SA 106 (Seamless pipes)
    • ASTM A 335 / ASME SA 335 (Seamless pipes)
    • EN 10216-2 (Seamless pipes)
    • EN 10217-2 (Welded pipes)
  • Line pipes with low temperature services

    We can supply pipes for the construction of pipelines, equipment and tanks subject to low temperatures as Seamless or welded pipes, hot rolled or cold finished. Pipe norms suitable for low temperatures are according to;

    • ASTM A 333 / ASME SA 333 (seamless and welded pipes)
    • EN 10216-4 (Seamless pipes)
    • EN 10217-4 (Welded pipes)

  • Seamless tubes for mechanical applications

    As per the norm EN 10297 specifies the technical delivery conditions for seamless round steel tubes.
    The tubes for mechanical applications are mainly used in those processes in which turning and CNC machines are used.

    The wide size range available, with OD from 21.3 to 812 mm, gives the possibility to manufacture several kinds of components for different applications: small machine parts, flanges, fittings, Archimedean screws, hydraulic cylinders for heavy machines etc.


  • Tubes for construction

    The round SEAMLESS tubes are hot rolled and satisfy both the requirements of the norm EN 10210 for structural applications and EN 10297-1 for mechanical applications.

    These steel tubes are fully killed and are suitable for structural applications but with the possibility to reach up to 100 mm w.t., which is impossible for welded tubes. These tubes are used for the manufacture of various kinds of construction components, above all where heavy wall thickness are required.

    • EN 10210-1/2 (structural applications)
    • EN 10297-1 (mechanical applications)
  • Hot finished or cold finished welded tubes with bead trimmed

    The round tubes are manufactured from a coil that is bent and electric resistance welded (ERW). The forming process can be according to EN 10210, which foresees hot forming or cold forming followed by heat treatment, or according to EN 10219, which foresees cold forming without following heat treatments. The finished product is fully killed and welding seam bead is inside and outside trimmed.
    These products are used to manufacture both welded and bolted structures, in the field of constructions, engineering,  industrial constructions, transports, automotive, agricultural machinery and earth moving machinery.

    The cold finished tubes are particularly suitable for structures at sight or for  aesthetical uses, thanks to the surface aspect typical of cold
    forming.

    NORMS

    • HOT FINISHED” TUBES EN 10210-1/2
    • COLD FINISHED” TUBES EN 10219-1/2
    • INSIDE TRIMMING EN 10217

  • Cold drawn tubes

    The different kinds of cold drawn tubes ready on stock cover a wide range of applications:

    • COLD DRAWN SEAMLESS AND WELDED TUBES SUITABLE FOR HONING.
    • COLD DRAWN SEAMLESS AND WELDED TUBES INSIDE H8.
    • COLD DRAWN SEAMLESS TUBES FOR SHAFTS.
    • WELDED SMOOTH BORE CYLINDER TUBES INSIDE H9 OR H10.
    • COLD DRAWN SEAMLESS TUBES FOR HYDRAULIC AND PNEUMATIC POWER SYSTEMS.

    Seamless and Welded Cold Drawn pipes honed or ready for honing;

    • H8, H9 or H10.
    • STEELGRADES AND DELIVERY CONDITIONS
      COLD DRAWN / HARD
      (+C acc. EN 10305 / BK acc. DIN 2391)
      No heat treatment after final cold drawing.
    • COLD DRAWN / SOFT
      (+LC acc. EN 10305 / BKW acc. DIN 2391)
      The final heat treatment is followed by a suitable drawing pass (limited reduction of area).
    • STRESS RELIEVED
      (+SR acc. EN 10305 / BK+S acc. DIN 2391)
      After the final cold drawing process, tubes are stress relieved in controlled atmosphere in order to reduce work hardening due to the cold forming process.
    • ANNEALED
      (+A acc. EN 10305 / GBK acc. DIN 2391)
      After final cold drawing process, tubes are annealed in
      controlled atmosphere.
    • NORMALIZED
      (+N acc. EN 10305 / NBK acc. DIN 2391)
      After final cold drawing process, tubes are normalized in controlled atmosphere at a temperature exceeding the austenitizing temperature.

  • Line Pipes

    Applications
    Pipes for the construction of pipelines for water, liquid hydrocarbons, natural gas and for the construstion of chemical and industrial plants, refineries etc.

    Norms
    Line pipes are according to the following norms:
    API 5L (ISO3183) (seamless and welded pipes)
    ASTM A53 / ASME SA53 (seamless and welded pipes)

    Manufacturing methods
    Seamless pipes, hot rolled or cold finished with following heat treatment:
    ERW pipes up to dia 24" and SAW pipes for the other sizes.
