Other applications include rolls and bandages of metallurgical rolling mills, mills for glass rolling, papermaking machines and sheet bending rolls; rollers for billets continuous die- casting machines, including bimetal; disk knives for coils cutting; sleeve blanks for internal-combustion engines; press mould blanks for machine building, abrasive, refractory and mechanical-rubber industry; casing and ring blanks for big bearings, electric motors, hydro-cylinders and pumps, valves (including ball valves); tube products operating in sea water, namely periscopes, oil platform columns, piles with anticorrosion oxide-silicon coating; heavy loaded construction columns; low waste billets in machine building for gas turbine stator rings; crane and brake drums; sleeves including wear- resistant bimetal; bandages, flanges, gears; billets for press instruments; tube billets for pilger mills, cone rolling mills, for press deformation. Centrifugally cast tubes have no alternative among the known tube manufacturing methods when seam- less large diameter heavy wall hard- deformed or non-deformed steel tubes are required. The production of abrupt bend offsets has been started, with a range from 22 to 630mm of carbon and stainless steel grades according to GOST and international standards requirements. The production of offsets made of titanium alloys, chemical- and high-resistance steel grades has also been mastered.

Thanks to the wide range of materials used, including stainless steels, duplex, superduplex, nickel alloys (Alloy C276- C22-B3-59-200-400-600-625-800-825)

Pressfitting system

Eurotubi’s Pressfitting is a system of tubes and fittings used for hydrothermosanitary installations, recommended for the conveyance of water, gas and compressed air. The fittings use an o-ring seating with a high resistance rubber seal, able to support high pressures and temperatures over 85°C. Tubes and fittings are assembled through the permanent defor- mation of the fitting by special pressing jaws mounted on small electromechanical tools. Once pressed, the o-ring ensures a hermetic, indivisible connection.

Eurotubi’s Pressfitting system is assembled S S using electromechanical tools with special pressing jaws

The Pressfitting system combines the reliability of joints with an easy and quick laying method, as it does not need any gluing, threading or welding. As a consequence, the major costs of fittings are balanced by the low cost of labour.

The system has a wide range of fittings available, in diameters from 15 to 108mm in stainless steel 316L, and 12 to 108mm in carbon steel.

The quality of materials, the constant sealing, duration tests and a rigorous quality control have allowed Eurotubi’s Pressfitting system to obtain conformity with the strictest European certifications. Carbon steel represents for thermal installations a competitive and innovative solution, offering the same quality level provided by traditional copper systems, but at lower costs. The Eurotubi Pressfitting system is compatible with many brands of fittings.

production in extremely short times, to face emergencies such as plant breakdown. The company also possesses an extensive stock of sheet, tubes and fittings. Officine Orsi operates a quality system qualified according to ISO 9001 by Lloyd’s Register, and is certified by TÜV. All products can be supplied with Rina, LLRR, NV, BV and TÜV inspection, in conformity with the PED 97/23/CE directive.

and titanium, the company is able to solve the most common problems concerning corrosion and high temperatures. Production is divided into three departments: welded pipes, fittings and pressure vessels. The wide range of fittings, with diameters from ½" to 40", includes elbows with radius from one to ten times the diameter, concentric and eccentric reductions, 90 and 45° T joints, stub ends, caps, collars, rings, threaded and socket welding fittings, flanges and special pieces to drawing. Experience and the flexibility of the production system make it possible to produce materials which are not commercially available in non-standard sizes and small quantities, including
