Arvedi tubes for pressure applications are high frequency welded (HFI) products in alloy and non al-alloy carbon steels. The excellent final characteristics are achieved using raw materials of constant and uniform quality from Arvedi Acciaieria ATA’s special production equipment which allows close dimensional tolerances to be respected. The results are better workability and repeatability in the welding, rolling expansion and curving phases. These tubes are mainly used ijn industrial and domestic boilers, high and low temperatures heat exchangers and in applications for the conveyance of pressurized fluids in the chemical and petrochemical industry. The tubes for pressure applications can be supplied in lengths up to 15 meters and in the following states: On request, in the order phase, it can be agreed to supply the tubes by completing the product documentation with PED (pressure equipment directive) certification in conformance with the requirements of PED 2014/68/EU or the certification AD 2000 W4/TRD 102. ENERGY AND POWER APPLICATIONS BOILER TUBES AND HEAT EXCHANGERS The reference standards are: welded and calibrated normalized in a controlled atmosphere seam annealed hot rolled EN 10217-1 for uses at ambient temperature EN 10217-2 for uses at high temperatures EN 10217-3 for fine grain alloyed tubes ASTM A214 electrically welded carbon steel heat exchangers and condensers EN 10217-4 for uses at low temperatures ASTM A178 electrically welded carbon steel tubes for boilers and heat exchangers Welding Relations
