Large size stainless steel welded pipes

Stainless steel welded pipes with large diameter is the core business of Inox Tech, the leading manufacturer located in Italy producing this niche component, mainly used for LNG plants, oil extraction and desalination-desulphurization plants.

With a covered and uncovered area of approx 80.000 square mtrs and 120 employees, 80% of working on three shifts, Inox Tech leads the market of the large size stainless steel welded pipes since mid 90s.
The strength of Inox Tech technology stands in the ability to manufacture a wide size range with small quantities as well as complete project supplies up to several kilometers and thousands of tones of pipes. This is called Inox tech flexibility, and has created the success of the company which is now at the top level in this market.

The Company is strongly customer-oriented, and focuses its targets to the main EPC contractors, who can be served with the most efficient documentation service, as well as with an efficient project management that allows the client to monitor production day by day.

Some examples of projects executed for the main global EPC contractors are:
Algeria (Saipem, Sonatrach) 7.000mtrs, 2.500Tons
Chile/Peru (CB&I) 9.500mtrs, 1.350Tons
Iran (OIEC, IOEC, Sepanair) 8.000mtrs, 2.000Tons
Korea (Korea Gas, Hyundai, Samsung) 5.000mtrs, 1.450Tons
Nigeria (KBR, Saipem, Shell) 12.000mtrs, 4.250Tons
Qatar (Chiyoda, JGC, Shell) 35.000mtrs, 16.000Tons
UAE (Petrofac, Gasco) 4.000mtrs, 1.000Tons
UK (CB&I, BP) 5.000mtrs, 1.200Tons.

The size range for the large diameter pipes covers from 24" up to 80", from 5 up to 50-60mm wall thickness, and all these sizes can be manufactured in 12 mtrs random length.
The manufacturing method varies from size to size, and it is mainly limited to the capability of the steel mills to manufacture such wide plates. These limits are easily exceeded by Inox Tech with its long term experience and a cut-to-size equipment that allow the mill to satisfy customers need in every single occasion.

The material range varies from the "normal" stainless steel, namely 300 series, up to duplex and superduplex, Nickel alloys, bimetal materials (clad) and have also a dedicated line for carbon steel for urgent deliveries.
The company designs, manufactures and updates by itself all the machines in the mill, and has just completed an investment plan of several millions euros for the set up of a new mill with new facilities dedicated to the manufacturing of stainless steel welded pipes, with large diameter.

The new mill is just in front of the old one, and will allow the Company to enlarge the production capacity as well as the production range.The mill has an annual production capacity of approx 25.000 tons, that will be increased by 25% by the end of 2011 when the second part of the investment plan will be completed.
