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.
Historically, Belden corrosion resistant brick linings have won wide acceptance because of these features:
• Usage flexibility without sensitivity to minor changes in chemical processes, and applicability for many different processes.
• Cost savings: where alloys and special metals become uneconomical because of accelerated chemical attack at high temperatures, chemical resistant brick liners inside the vessel can lower temperatures and concentration levels, making it feasible to use less expensive alloys.
• Repairability compared to the finite durability of alloys.
• Insulation inside a vessel is less susceptible to damage than is
external insulation.
• Cooler operation reduces degree of external protection necessary
for worker safety.
Quality ... from the ground up
Belden chemical resistant brick, backed by more than 100 years of brick making experience, are manufactured of specialty selected American shales and fire clays. These are fine-ground and specifically formulated for density and strength and fired at over 2000ÍF. This process results in brick that resists virtually all corrosive liquids and gasses, except for acid fluorides and strong hot caustics.
