PVE recently constructed three acid towers ranging from 8-12 feet in diameter and from 48-55 feet tall. They are constructed from 304, 316L, 310S and Zecor Stainless Steels at different elevations to provide superior corrosion resistance at elevated temperatures. These units were built with a 3 mm tolerance. The towers were shipped overseas via sea transport. Picture features one of the towers prepared for shipping to sea transport.
