Industrial piping, our historical know-how and essential applications for hydrogen

Complex industrial piping is our core business.

Drawing on the expertise we have gathered since 2004, we produce steel, stainless steel and other metal pipes that are specialised for use with fluids at cryogenic temperatures (- 250ºC), high temperatures (200ºC), high pressure (1,000 bar or 100 MPa) or very low pressure (10-6 mbar)
