Product category: Formed tubes

Tubes

SOTEP transforms standard tubes (known as basic or draft tubes) into precision tubes by means of a cold drawing process.
Drawing involves cold pulling a bar or a tube through a die to reduce its cross-section and increase its length. This is a process which enables the outer and inner diameters to be calibrated according to criteria set by the customer, with good control of dimensional tolerances, a good surface finish and mechanical properties as required by the stipulated standards or specifications.

The drawing process uses a die which calibrates the outer diameter of the tube and internal tools to calibrate either the thickness or the internal diameter.

Tube parts

SOTEP also aims to provide its customers with additional support, no longer only supplying raw material in the form of precision tubes but also precision tube parts...

... this is an additional step towards providing a comprehensive service, with the objective of supplying functional parts ready to be integrated onto the piece of equipment or installation. SOTEP is at your service to optimise your logistics chain.

In order to do so, SOTEP has reinforced its technical team and acquired suitable manufacturing facilities, while relying on the services of flexible and qualified local partners for special processes.

SOTEP thus ensures quality control of sub-contractors and the continuity of its manufacturing processes while limiting the risks linked to transport.

For internal manufacturing processes, SOTEP designs its own tools and machines to create parts. Given the size of the batches worked, this is the most viable techno-economic solution for customers.

Applications

SOTEP supplies tubes and tube parts to the most demanding industries: aeronautics, nuclear energy, medicine, high pressure applications, oil, exploration, etc.

Dimensional precision, obtaining special mechanical characteristics, mastery of special processes, and meticulous surface finishes are just some of the criteria that lead high-ranking manufacturers to work with SOTEP.

SOTEP's know-how and mastery in terms of the processes applied enable it to manufacture tubes and parts in very small dimensions (small diameters and small thicknesses such as capillary tubes), and also with very high diameter/thickness ratios enabling flow optimisations while controlling mass.

Products manufactured by SOTEP are installed on often extreme applications - whether in the middle of a nuclear island in very high temperatures and under very high pressures, inside a gas or oil well, in corrosive atmospheres (NACE MR0175-MR0103) and under very high pressures, on aircraft engines, in vibratory environments requiring a high level of fatigue resistance, in security organs, etc. SOTEP's quality and rigour are the assets required for the successful achievement of such projects.

Moreover, SOTEP is not just a manufacturer of tubes and tube parts - it is also a quality organisation structured around its Quality Department for the successful completion of projects which are highly demanding, not only from a technical point of view, but also in terms of documentation (quality plan, PTF (technical manufacturing programme), RFF (end of manufacturing report), etc.).

About us

Company details

The Société Technique d’Étirage de Précision (Technical Precision Tube Drawing Company - SOTEP) was created in 1980.
SOTEP was created in 1980 on its current Chouday site, in the Indre département in France. Installed on a site in the heart of the Berry countryside, the SOTEP factory has grown significantly over the years, growing from a building of 800 m2 to a covered complex of 6,400 m2. Endowed with generous land reserves, the site is conducive to the future development of the factory.

SOTEP's main activity is the manufacture of stainless steel precision tubes in small and medium quantities, in order to meet manufacturers' needs in terms of specific products that neither steelmakers nor stockists are able to supply to them. For some years now, SOTEP has also been supplying metal tube parts from tubes the company manufactures so as to help its clients to shorten and optimise their supply chain for their specific tubing needs.

With expertise developed over several decades of manufacturing hundreds of thousands of metres of tubes, SOTEP has experienced employees with real know-how, a solid command of the processes for manufacturing tubes and an increasing number of very high quality tube parts, meeting very advanced specifications for highly demanding market segments such as aeronautics, the nuclear industry, oil exploration, the medical industry, etc.

SOTEP is today a recognised precision tube stakeholder at international level, its influence going far beyond France. Thanks to the company's partners (OEMs, end users and distributors), SOTEP tubes are to be found in China, in the Taïshan, and Hualong nuclear power plants, in Slovenia, Sweden, Belgium, in refineries in the Middle East, in oil fields all over the world and in the air, on the entire Airbus range, on the Rafale, on helicopters, etc.
