Welding Relations
HIGH TECHNOLOGY & EXPERIENCE 3 Welding Relations Advanced technology, experience consolidated over the years, the constant search for quality, flexibility and customer service are the main pillars of Arvedi Tubi Acciaio S.p.A, a leader in welded tube for special applications. With a production capacity of over 600,000 tpy, the Cremona-based company holds a consistent market share in the automotive, mechanical applications, heat transfer, pressure equipment, piping, industrial and civil constructions. Its stretch-reducing mill and HFI welding lines, fitted with the most advanced automation technology, allow customer to be offered a vast range of products that can meet the strictest requirements and standards. ATA’s production range meets the requirements of three basic areas of application namely special, energy and civil engineering and includes round tubes and pipes in diameters from 17.2 to 355.6 mm. Square hollow section can be produced from 100x100 to 300x300 mm and rectangular hollow section from 120x80 to 400x200 mm in a range of wall thicknesses from 1,2 to 16 mm.
Starting with black and galvanised gas and water pipe production with the trademark Arvedi LC (hot rolled), in two years the company was able to propose a new product, GSM, heavy wall hot reduced tube for specialist applications. The excellent degree of workability, appreciated by users of Arvedi LC® and GSM® tube, is the result of a controlled hot reduction process which, besides supplying the tube in the normalized state, guarantees complete homogeneity of the material’s mechanical and physical characteristics. The SRM produces the whole range of tubes in diameters from 17,2 to 88,9 mm in wall thicknesses from 1,8 to 12,5 mm. 4 Arvedi hot rolled tubes (Arvedi LC® and GSM®) are produced on the hot stretch-reducing mill, a unique plant that allows to obtain small and medium diameter tubes with the internal bead removed. The plant dates back to 1974 when the stretch reducing mill (SRM) was installed downstream from a high frequency welding line (HFI), an absolute innovation in Europe. HOT STRETCH REDUCED
5 ARVEDI GSM® TUBES ARVEDI LC®/GSM vs SEAMLESS The characteristics of homogeneity and workability of Arvedi hot stretch reduced tubes are enhanced in the heavy wall mechanical tubes (GSM®) where the ratio between wall thickness and diameter is pushed over 30%. GSM tube presents a smooth internal surface without the welding bead, even for small diameter and heavy wall products, as it is rolled from a large diameter welded tube whose bead has been removed. GSM is therefore suitable for cold drawing and for all mechanical processing’s which require a good internal tube surface. Welding Relations The uniqueness of Arvedi process is due to the rolling of HFI welded mother shell on stretch reducing mill. The Arvedi mother shell is not obtained from billet “piercing” (as for seamless process). In addition, the Arvedi mother shell is generated from a strip with limited thickness variations. All these peculiarities guarantee superior geometrical characteristics and negligible or limited internal polygonality. Synergy with Acciaieria Arvedi allows to develop new products made with special steels and aimed at specific projects. The production line from the steel to the finished and pre-processed tube responds with ideas and solutions, even personalised ones, to the most varied demands. ECCENTRIC SEAMLESS CONCENTRIC ARVEDI LC/GSM eccentricity absent or negligible both in the cross section and along the tube length

12 PRECISION TUBES APPLICATIONS 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 compliance with standard EN 10305-3 and in accordance with customer specifications. These tubes, which have the most severe prescriptions on dimensional tolerances are often processed with deep deformations and the obtained finished products are then frequently subjected to occasional loads or continuous fatigue stress. Industrial parts, machinery such as rolls, moving structures and crane parts are examples of their applications. ARVEDI Mother shell for cold drawing represent ATA’s core business; for this specific application, ATA confirms its position as a leader in Europe and the only independent supplier of these products. These tubes can be produced as hot stretch-reduced or welded from black or pickled stripe and according to standard EN10305-3, EN10210, EN 10296 or to customer specification; 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 shell are suitable for cold drawing to obtain tubes with close tolerances and low roughness used in particular in the automotive sector and hydraulic or pneumatic industry. WELDED PRECISION TUBES MOTHER SHELL FOR COLD DRAWING
Welding Relations 13 PRECISION TUBES APPLICATIONS The high frequency induction welded (HFI) precision tubes produced by ATA in accordance with EN 10305-3 and / or in accordance with customer specifications are used 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 IATF 16949. Thanks to a team composed of engineers and experts in the sector, ATA supports customers during the various project phases, from steel choice to the development of the product and 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 innovative ISP and ESP processes with controlled thickness, mechanical and physical characteristics, properties appreciated by car manufactures which become constancy and uniformity of behavior under processing and then in performances on the vehicle. Subsequent processing carried by the customers includes bending, hydroforming, cold and hot forming and mechanical processing for making small and large series of automotive parts such as axles, camshafts, stabilizing bars, chassis parts, engine and bodywork supports and reinforcements and safety parts. Integration upstream with Acciaieria Arvedi guarantees short supply times of the raw material and considerable production flexibility. Integration downstream with Metalfer Spa and Metalfer Automotive offers the end customers the possibility of receiving the cut-to-size tube on a just-in-time basis. ARVEDI AUTOMOTIVE TUBES
14 ENERGY AND POWER APPLICATIONS 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 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 in 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 together with PED (pressure equipment directive) certification in compliance with the requirements of PED 2014/68/EU or the certification AD 2000 W4/TRD 102.
