Vallourec says that it has finalized the sale of Serimax, Vallourec’s subsidiary specializing in manual and mechanized orbital welding solutions, for an enterprise value of €79 million (US$92.7 million).

The transaction is part of Vallourec’s initiatives to rationalize its invested capital and focus the company on its core business as a seamless tubular solutions provider. 

As part of this process, Vallourec says that Serimax has undergone a “rapid transformation” and is now operating profitably as a standalone company. Serimax generated approximately €105 million (US$123.2 million) of revenues in 2024.

As a new shareholder, Aldebaran, a French investment company, will enable Serimax, a global provider of manual and mechanized orbital welding solutions, to continue its development plans.
