Sosta manufactures austenitic, duplex and nickel alloy welded stainless steel pipes both from coil and from plate. During continuous production from coil, in one single operation the base material can be formed into a pipe, welded, heat-treated and subjected to non-destructive testing. All welding processes are controlled by laser seam tracking equipment to optimize the quality of the weld seam.
For the production of pipes from single stainless steel plates, the base material is formed into a pipe on the press brake or in the three roll bending system, subsequently welded by fully automated welding equipment and afterwards heat-treated.
Destructive and non-destructive testing on base materials, longitudinal and circumferential welds are done in our in-house testing facilities.
All pipes are pickled and passivated in our 13 meter long pickling facilities.
