SEYAME specializes in seamless cold drawn stainless steel tubes in straight length and in coils . In addition we have a complete offer of centrifugal casting tubes . We deliver all over the world but our market is 95 % European . We are constantly strengthening our range in order to offer a global solution to our customers . Seyame started with stainless steel tubes , then we developed steels , aluminum , special grades and we are associated with the American tube cutter machines producer VULCAN PARADIGM for whom we are the exclusive representative in EUROPE .

Straight tubes The tubes in straight lengths are the most used in industry , our ranges extend from diameter 3 to 114.3 mm with thicknesses varying from 0.5 to 5.5mm . Lengths from 3 to 18 meters . We produce almost all austenitic and refractory grades with all finishing methods . We mainly produce cylinder tubes , hydraulic tubes , exchanger tubes and precision tubes for mechanical applications . Our capacity is approximately 2000 tons / year .

Coils tubes The tubes in coils are more technical to produce than the straight lengths , they answer a need for a continuity and a homogeneity of the circuit over great lengths , mainly used in the applications of oil and gas , hydrogen ... Our ranges extend from diameter 3 to 38.1 mm with thicknesses varying from 0.4 to 2 mm . The lengths depend on the dimension because the starting blank is always 100kg , the final coil will therefore be 100kg divided by the weight per meter of the dimension +/ - 10 %. Length extensions are possible by orbital welding of several rings together , maximum 3km depending on the nominal diameter . We mainly produce bright annealed 316L , other grades are available on request but always bright annealed . Our capacity is approximately 800 tonnes / year .

Centrifugal tubes Centrifuged tubes allow obtaining a high purity steel with very high mechanical characteristics much better

than traditional casting systems , ideal for highly stressed shafts or bearings , moreover centrifugal casting allows obtaining flared shapes , bi-material tubes and we also offer the machining of these tubes for the production of your finished parts . Our production capacity is approximately 7000 tons / year and 80 % of our production is ordered directly machined by our customers . Our ranges extend from diameter 60 to 2300 mm with a minimum thickness of 15 mm and a minimum internal diameter of 22 mm for a maximum unit weight of 5 tonnes and a maximum length of 4 meters . Extensions up to 8 meters can be made by welding , but the depth of the weld cannot exceed 200 mm . The applications that use these tubes the most are oil and gas , marine construction , pumps , settlers , compressors , galvanizing and printing machines , motors ... Almost all nuances are possible .
