alloy20-seamless-steel-square-pipe were initially developed to be used in an environment with exposure to sulfuric acid mostly in pulp and paper mills. Later on, due to the corrosion resistance properties of alloy 20 tubes, their bandwidth was increased to accommodate petrochemical, power generation, and chemical industries.
