stainless steel tubes

High quality welded tubes

including flaring, flattening, reverse bending and expansion, in order to evaluate the integrity of the weld area. In addition, in order to guarantee the integrity of the whole tube wall, 100 per cent of production is eddy current tested off-line. The Ilta Inox production programme includes round tubes in a wide range of austenitic stainless steel grades including 304, 304L, 321, 316, 316L, 316Ti, 316SL, 310S, 31803, and 309. The company has recently extended the size range of its production to include tubes up to 711mm OD, with annealed tubes now available up to 219.1mm OD.

incoming material using a portable spectrometer, followed by further laboratory analysis to verify the exact chemical composition. A wide range of grades and thicknesses are held in stock to ensure that customer requirements can be met quickly. Slitting of coil feedstock is carried out in-house on coils up to 30 tonnes, followed by welding with laser welding lines, and subsequent pickling to remove every trace of ferrous and oxidising contamination, which could be detrimental to corrosion resistance. Ilta Inox has the capability to pickle tubes in lengths up to 18m. Tubes produced by Ilta Inox are subjected to a constant on-line dimensional check (laser OD checking), as well as continuous destructive tests,

Ilta Inox, founded in 1963, produces welded stainless steel tubes, supplying demanding industrial sectors such as power generation and the chemical, pharmaceutical and food industries. With its modern production facilities, Ilta Inox can guarantee products that meet stringent market requirements, and that are certified by important international testing organisations. The company has been certified according to ISO 9002:1994 since 1994, and according to ISO 9001:2000 since 2000, and is also certified to AD 2000-Merkblatt-TRD 100 97/23/EC (PED), and has ISO 14001 environmental certification. Raw material is purchased only from suppliers who are ISO 9000 certified. Before processing, the company undertakes a 100 per cent check on in manufacturing stainless and nickel alloy tubes. It is a rapidly expanding company, and since 2005 has had two production units, located in Delebio and Gordona, covering a total surface area of 7,000m 2 . The company produces redrawn precision tubes, both in bar and coil form, by using the TIG welding process. The company offers a modern, well-equipped department for tube cutting and is able to produce cut pieces measuring just a few millimetres in length, completely burr-free. Tecnofar SpA specialises

urgent requirements, the family-owned company can produce pipes with wall thicknesses from 6.35 to 12.7mm. The company also specialises in storing steel plate in duplex or super duplex. Butting can manufacture, within a very short time, duplex pipes (UNS 31803 or UNS 32205) in wall thicknesses from 4.78 to 22.7mm. H Butting GmbH & Co KG – Germany info@butting.de www.butting.de

steel pipes are required, even in small numbers or in special sizes or materials, Butting manufactures them from steel plate. The company has enlarged its stocks of the necessary pre-materials, to ensure that they can satisfy individual pipe requirements with short delivery times at a high level of quality. As well as the standard materials, 1.4541 and 1.4571, the company’s store in Knesebeck also includes steel plates of TP 304L and TP 316L. To cover

H Butting GmbH & Co KG, Germany, is able to supply individual solutions to customers who require duplex pipes for urgent repairs, who have to cover shortages of thick-walled pipes at short notice, or who need pipes in special sizes as quickly as possible. Since stainless steels were first developed, the production of high- quality longitudinally welded pipes has been the company’s focal point. When longitudinally welded stainless
