Acid & Corrosion​

Belden shale and fire clay chemical resistant brick offer engineers a wide range of utility in environments that involve aggressive corrosive conditions and elevated temperatures.

These brick are currently in use in such industries as chemicals, steel, and metalworking, pharmaceuticals, pulp and paper, food and beverage, public utilities, aircraft, automotive and electronics. Typical applications in these industries are represented by process vessels, plating tanks, storage tanks, reaction vessels, fume ducts, scrubbers, bleach towers, waste treatment pits, rinse lines, and pickling tanks.

Chemical resistant masonry construction is designed to protect containment tanks and vessels made of steel, concrete, ordinary masonry, fiber-reinforced polyesters and the like. Chemical resistant brick provides thermal, mechanical, and chemical protection for these kinds of structures.

Belden chemical resistant brick is a particularly versatile construction material for sulfuric acid plants when installed as linings for carbon steel shells. These linings can be used regardless of the size of the vessels or equipment when prescribed construction techniques are followed. They can lower the temperature of the surface of the shell and eliminate erosion of the protective sulfate film. No other system of corrosion resistance can provide the same level of cost effective protection in wet areas where acid concentrations vary from 2% to 98% and at high temperatures, as the three component system using chemical resistant brick and mortar with a membrane backing.
