DELFIN TUBES SA
Delfin Tubes SA is a Spanish Sociedad Anonima registered in the Mercantile Registry of Asturias under registration number (CIF) A52557030. The company traces its current legal form to 10 November 2017, when it was incorporated as Delfin Tubes Fabrication, S.A.U., one of two beneficiary entities created when the original Delfin Tubes, S.A. underwent a total corporate scission (escision total) on 29 June 2018. The new entity assumed the "Delfin Tubes" corporate designation and continues to operate from the same site in Gijon, Asturias. Its current registry status is active.
Delfin Tubes SA manufactures finned and studded (extended-surface) steel tubes and related heat-transfer equipment, classified under CNAE code 2420 (manufacture of steel tubes, pipes, hollow profiles and accessories). Its products are used in the petrochemical, oil and gas, power generation and waste-heat-recovery sectors, supplying heat exchangers and furnace components to engineering contractors and end users that the company’s own published references identify as including Tecnicas Reunidas, Repsol, BP Oil and ExxonMobil. The company’s plant is located near the Port of Gijon (El Musel) on Spain’s northern coast.
Delfin Tubes SA is not listed on any stock exchange.
Registry-linked business databases (Axesor) classify Delfin Tubes SA as a medium-sized enterprise with approximately 87 to 90 employees as of 2025 and an estimated annual turnover band of EUR 3,000,001 to EUR 50,000,000. These figures are third-party registry-derived classification estimates rather than figures drawn directly from filed annual accounts and should be read accordingly. The most recent Mercantile Registry filing identified during this review was published in the Boletin Oficial del Registro Mercantil (BORME) on 21 November 2023.

Group Structure
Group structure of Delfin Tubes SA
No verified parent, subsidiary or sister-company relationship for Delfin Tubes SA could be confirmed through the official Spanish and Italian registry sources reviewed for this profile. Zavia’s underlying registry-linked data associates Delfin Tubes SA with an Italian entity recorded as "Fidastur SPA" (Italian tax identifier IT03190940126) in a group/ownership record, but this association could not be independently corroborated through the Spanish Mercantile Registry, BORME filings, or the Italian Registro Imprese, and is therefore presented here as a possible, unverified relationship rather than a confirmed parent company. Delfin Tubes SA’s own published company history describes it as a private company founded in 2000 and does not reference a holding company or corporate group. No direct or indirect subsidiaries of Delfin Tubes SA were identified.
