Line Pipes

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)

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)

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...

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.
