Tubes for boilers and heat exchangers

seamless and welded tubes for high temperature and high pressure service.
Fields of application: these tubes are incorporated, providing high efficiency, into the equipment and processes of power generation, heat transfer, solar thermal, chemical and petrochemical industries; e.g. in boilers, heat exchangers, condensers, etc.
Heat exchanger tubes can be supplied in straight lengths or U-bent according to DIN 28179 or ASTM A556.
