Arvedi Tubi Acciaio

BOILER TUBES AND HEAT EXCHANGERS Arvedi tubes for pressure applications are high frequency welded (HFI) products in alloy and non-alloy carbon steels. The excellent final characteristics are achieved using raw materials of constant and uniform quality from Acciaieria Arvedi and 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 in industrial and domestic boilers, high and low temperature heat exchangers and in applications for the conveyance of pressurised fluids in the chemical and petrolchemical industries. The reference standards are: EN 10217-1 for uses at ambient temperature EN 10217-2 for uses at high temperatures EN 10217-3 for fine grain alloyed tubes EN 10217-4 for uses at low temperatures ASTM A214 electrically welded carbon steel heat exchangers and condensers ASTM A178 electrically welded carbon steel tubes for boilers and heat exchangers The tubes for pressure applications can be supplied in lengths up to 15 metres and in the following states: - welded and calibrated - normalised along the weld area - normalised in a controlled atmosphere - hot rolled On request, in the order phase, it can be agreed to supply the tubes by completing the product documentation with PED (pressure and equipment directive) certification in conformance with the requirements of European Directive 97/23/EC and/or AD 2000 TRD 102/ADW4 certification. DISTRICT HEATING Arvedi produces and supplies tubes for district heating in line with the provisions of standard EN253 and stringent customer specifications. ARVEDI tubes for district heating are welded tubes produced in accordance with the series of standards EN 10217 and can be supplied seam annealed or full body normalised, they are made in steel grades provided by the standards or in special steel grades in accordance with customer specifications and ensure use in extreme conditions; depending on the application requirements the ARVEDI tubes can be supplied in lengths ranging from 6 to 16 metres. As completion of production documentation Arvedi Tubi Acciaio can provide PED (pressure equipment directive) certification in compliance with the requirements of European Directive 97/23/EC. WATER PIPE Arvedi Tubi Acciaio uses high quality carbon steels characterised by excellent physical and mechanical properties. The repeatability of these characteristics allows tubes to be obtained that are highly weldable and workable in the installation phase. The water pipes are produced with (HF) longitudinal welding from hot rolled strip, comply with the prescriptions of standard EN 10224 and can be coated externally with polyethylene and lined internally with epoxy varnish. Arvedi water pipes are made and supplied in compliance with standard EN 10244 and CE certified (in accordance with European Directive 305/11 CE) and are accompanied by a performance declaration (as per directive EU 305/2011). LINE PIPE ARVEDI line pipes are tubes destined for conveying pressurised fluids and are typically used in the civilian and industrial oil and gas sectors. These pipes are supplied both crude and coated in polyethylene and are produced and supplied in accordance with standard API5L and ISO 3183. ATA produces line pipe using high frequency (HF) induction welding without the addition of filler materials. e n e r g y a n d p o w e r A P P L I C A T I O N S ARVEDI PRECISION TUBES Welded Precision Tubes Starting from steel strips, produced by Acciaieria Arvedi, which guarantee constant mechanical characteristics and close wall thickness tolerances, ATA produces high frequency induction welded (HFI) precision tubes in conformance with standard EN 10305-3 and in accordance with customer specifications. These tubes, which have the most stringent prescriptions on dimensional tolerances are often processed with deep deformations and the obtained finished products are then frequently subjected to occasional or continuous fatigue stress. Industrial plant parts, machinery such as rolls, moving structures and crane parts are examples of their applications. Mother shells for drawing ARVEDI mother shells for cold drawing represent ATA’s core business where it is the leading European company and the only independent supplier of these products. These tubes can be produced as hot stretch- reduced and welded, and rolled from cold welded black or pickled strip, to standards EN 10305-3, EN 10210, EN 10296 or to customer specifications; they are made in a wide range of steel grades and in the full size range of diameters from 17 to 355.6 mm and wall thicknesses from 1.5 to 16 mm. ARVEDI mother shells for drawing are suitable for cold drawing to obtain tubes with close tolerances and low roughness used in particular in the automotive sector and cylinder industry. ARVEDI AUTOMOTIVE TUBES The high frequency induction welded (HFI) precision tubes produced by ATA in compliance with standard EN 10305-3 and/or in accordance with customer specifications are used in in the car and truck components sector. Arvedi Tubi Acciaio is an appreciated supplier of the leading car manufacturers and their subcontractors. The quality management system at Arvedi Tubi Acciaio in Cremona is certified ISO TS 16949 . Thanks to a team composed of engineers and experts in the sector, it supports its customers in the various project phases, from the choice of steel to the development of the product down to the launch of the finished series, guaranteeing efficient after-sales assistance. Synergy between Acciaieria Arvedi and ATA leads to the development of specific steel grades dedicated to individual projects. Once they are series, these grades are produced with the innovative ISP and ESP processes with controlled thickness, mechanical and physical characteristics, properties appreciated by car manufacturers which become constancy and uniformity of behaviour under processing and then in performances on the vehicle. Integration upstream with Acciaieria Arvedi guarantees short supply times of the raw materials and considerable production flexibility. Integration downstream with Metalfer SpA and Metalfer Automotive offers the end customer the possibility of receiving the cut-to-size tube on a just-in-time basis. Subsequent processing carried out by the customer includes bending, hydroforming, cold and hot forming and mechanical processing for making small and large series of automotive parts such as axles, camshafts, stabilising bars, chassis parts, engine and bodywork supports and reinforcements and safety parts.
