Among the variety of carbon steel pipes offered in the market, there are galvanized pipes, which are characterized by their high corrosion resistance, made possible by the hot-dip galvanization process the product undergoes.
Hot-dip galvanization involves applying a protective layer to the metal surface by immersing the steel in a bath containing molten zinc. The goal is to protect the steel pipes against corrosion, extending the product’s lifespan and providing a better finish. In practice, oxidation affects the zinc layer, preserving the steel structure. Because of these characteristics, galvanized pipes are an excellent choice for use in fluid conduits, electrical cable networks, and the construction of metal structures.
At Tuper, galvanized pipes, both structural and for conduits, meet strict manufacturing standards in accordance with criteria established by technical regulations.
Pipes that meet ABNT NBR 5580 receive a 400 g/m² zinc layer, while pipes that meet ABNT NBR 5590 feature a superior protective layer with 550 g/m². Both are designed for non-corrosive fluid conduits used in water, gas, compressed air, oil, and steam pipelines.
The ends of conduit pipes can be smooth, beveled, grooved, or threaded – BSP or NPT – according to the pipe standard. Threaded ends are also protected with anti-corrosion oil and come with a plastic protective cap.
Pipes conforming to ABNT NBR 5597 and NBR 5598 standards, which meet the requirements for rigid galvanized electrical conduits used for the passage of wires and electrical cables, receive a 300 g/m² zinc coating suitable for the technical specifications of the regulatory standard.
ABNT NBR 8261 standard regulates pipes for structural uses. These pipes receive a 300g/m² zinc coating and are recommended for use in civil construction for metal structures, scaffolding, columns, foundation piles, the photovoltaic energy sector, among others, and for various market segments, including automotive, agribusiness, and general industry.
With one of the most modern production lines in South America, Tuper was one of the first companies in Brazil to carry out continuous hot-dip galvanizing from the year 2010 onwards. This means that, unlike the dripping method, Tuper’s tube galvanization process is done continuously, with control of the internal and external layers, making the layer completely uniform. Also included is normative printing for traceability with manufacturing information.
