1949. The initiative of three entrepreneurs, Messrs. Alfredo Evangelista, Armando Canosa and Roberto Marchese, who joined efforts in the late forties, led to the constitution of ALFREDO EVANGELISTA y Cia SRL, a company engaged in the design/construction of equipment and projects for the oil, gas and petrochemical industry

The first workshop of the firm was at Salom and California, in Barracas neighborhood, to support the execution of electro-mechanical construction agreements. The equipment to be later mounted at the works was pre-manufactured and assembled at this shop.




1950. From this year on, having entered the market fast, the company performs uncountable field supplies and assemblies, mainly of oil storage tanks (batteries), oil pumping plants and storage plants.

1951. Plaza Huincul draining system is built when the city was incipient and Route 22 was just a trail on the soil. A colorful touch: sending the materials from Buenos Aires took nine days.

1954. Las Flores-Buenos Aires Gas Pipeline is built. Fabrication of Heaters and Furnaces for the oil industry starts.

1957. Fabrication of shell and tube heat exchangers starts.

By the end of this decade the company purchases the land, builds the sheds and installs what would become Villa Zagala Workshop.

Clients: Y.P.F. (Yacimientos Petrolíferos Fiscales), Gas del Estado and Pan-American are the main clients at this time.

The company is engaged in the supply and assembly of tanks for product storage, and the fabrication and supply of process equipment is intensified. Highlights: the construction of four portable gas dehydration and liquefied gas and gasoline recovery plants for Gas del Estado, under design of Portable Gasoline Plants Inc., Tulsa, Oklahoma, as well as Algarrobo y Plaza Huincul pumping plants. Also in this decade, bubble and distillation towers are manufactured, pioneering this activity in the country.

1960. The same founding partners, under the corporate name Siderúrgica Termec S.A., start installing a Plant for valve fabrication in the town of Canning, Province of Buenos Aires, a place that would over the years concentrate all the business of the company and would become Canning Plant. The plant was manufactured and built by Alfredo Evangelista y Cia SRL.

1964. The company starts subscribing agreements with different foreign firms, aiming at obtaining the Licenses for local fabrication of equipment that was so far imported. The most substantial agreement was subscribed with Graver Tank to fabricate floating roof storage tanks; this agreement allowed the Company to become a leader in the fabrication and assembly of storage tanks of all types and sizes.

1969. Alfredo Evangelista y Cia S.R.L. becomes Alfredo Evangelista y Cia S.A.

Clients: The portfolio of clients expands to include SAIPEM, ASTRA CAPSA and Bechtel.

The company continues fabrication of tanks, and the manufacture of 20, 30 and 40 million liter tanks is usual, as, for instance, those installed for Yacimientos Petrolíferos Fiscales in La Plata, Allén, Puerto de Barranqueras and Puerto Rosales. In this town, a storage plant is installed including the largest fixed roof tank fabricated and assembled in the country. The tank was fabricated at Villa Zagala Workshop.

This decade was particularly complex due to the great economic difficulties the country went through, such as suspension of imports, inflation, etc., in addition to the sharp increase in the price of steel products at global level and the large quantity of Russian storage tanks that were exchanged for grains and caused fabrication of this product to decrease towards the end of this decade.

Despite the difficulties, important projects were executed -as regards their complexity, size and economic values- which enabled the growth and consolidation of the company.

1972-1975. Design and construction of model storage and dispatch plants in Villa Mercedes (San Luis), Junín (Buenos Aires) and Luján de Cuyo (Mendoza) for Yacimientos Petrolíferos Fiscales.

1973-1978. Alfredo Evangelista y Cia S.A. takes over Siderurgia Termec owned by the same partners. The existing installations are recycled and three new industrial bays are built, the thermal treatment oven and a warehouse, leading-edge imported equipment is added. Thus, Canning Plant is born, built by the same company. Villa Martelli and Villa Zagala workshops are closed, and all activities are concentrated in Canning, and the commercial, technical and administrative offices in the Federal Capital. At this time, more design and manufacture license agreements were subscribed, such as:

With O´Neill Tank Co, from Great Bend, Kansas, USA, and Process Equipment International Inc, from Tulsa, Oklahoma, USA, for the development and manufacture of electrochemical Heaters and Treaters.

With Rainey Corporation, from Tulsa, Oklahoma, USA, to design and manufacture Air Coolers and Condensers.

With Chitton Equip. Inc. from Tulsa, Oklahoma, USA, to manufacture industrial fans and air-driven shutters.

For this undertaking, Petromin SA. is created.
