Always striving for quality and new technologies in the production of seamless stainless steel tubes,we can produce high-quality tubes in accordance withall major specifications and grades. The millmanufactures hot-extruded pipes and cold finished tubes and pipesto more than 100 standards. Our product range covers austenitic, ferritic, austenitic-ferritic steel grades, duplex,super duplex, nickel alloys in a dimensional rangeOD 4 – 250mm with wall thickness of 0.2– 35mmand a maximum tube length of 25 metres includingU-tubes OD 12.7-38.1mm ( ½ –1 ½ inch) with maximumlength of 25 metres.

Currently Centravis ranks as one of the leadingglobal producers of seamless stainless steel heat-exchanger tubing. Products are supplied for a variety of applications that involve heat transfer processes, including solutions for nuclear steamgenerators. Year by year the product range is increased, technological processes improve, efficiency andproductivity increases. During the last years our mill at Nikopol gradually increased its production volume of high quality heat-exchanger tubes. These positive trends are accompanied by the expansion of our geographic distribution.All in all we are delivering product solutions to morethan 70 countries.

In order to continue the development Centravishas launched a new highly productive 44 MN press line producing OD 57 – 250mm, and a new streamlinefor heat-exchanger tubes manufacturing. The streamline includes new and highly productive cold pilgermills (KPW –25), bright annealing furnace, straightening, grinding machines, cutting machine and testingequipment, provided by leading European suppliers.

Technical requirements

U-BENT TUBES:

Straight tubes for bending (ASTM/ASME A/SA 213; ASTM B 163; ASTM B 729; ASTM B 407; ASTM B 423; ASTM A 789;DIN 28180; EN 10216-5)

* − Tubes of other alloys and steel grades can be produced in trial lots.

22

Heat Treatment:

Heat treatment is carried out by resistometric method on a curved part of the tube and on straight parts 300 mm in length by heating the tube to the required temperature (see table below), and then soaking and rapid cooling of the tube to the temperature 370 C & below. Nitrogen blow-off tubes used before and during the process of heat treatment to protect the inner and outer surface from oxidation.

Marking − before bending by marking machine all over the tube length (bent section after heat treatment without marking). Marking is also possible after bending on the straight parts of U-bent tube. Packaging − closed wooden boxes of corresponding dimensions for each tube length, radius, diameter, according to PO requirements or in bundles wrapped in polyethylene film with plastic clamping spacers on each tube. Transportation − a truck with capacity of 20 tonnes, body length 13.6 m, width 2.46 m.

BENDING RADIUS − from 1.5 OD to 1250 mm. When ordering tubes with R ≤ 1.5D it is necessary to agree precision of geometrics. STRAIGHT TUBES MAXIMUM LENGTH (before bending) − 26 000 mm upon agreementLEG LENGTH − min 1 meter, max 10.5 meters (for max R=1250 mm)HYDROSTATIC TEST − maximum test pressure 600 bar, soaking 10 sec. with demineralized water. Compressed aircleaning after hydro-test.
