Heat treatment - Import export

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)

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.

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.
