Refractory and Acid-Resistant Linings for Process Plants

Chemical, fertilizer, and pigment plants can combine high-temperature duty with acidic or chemically aggressive service. The process medium, equipment zone, temperature, permeability requirement, and jointing system must be identified before selecting either a heat-resistant or acid-resistant lining.

Common lining requirements

  • Process-heater, furnace, and boiler refractory linings
  • Acid-resistant brick and tile lining systems
  • Compatible sodium- or potassium-silicate mortars
  • Thermal insulation and maintenance castables

Typical equipment and lining zones

Process furnaces, heaters, boilers, and incinerators
Sulphuric-acid and fertilizer process areas
Chimneys, ducts, tanks, and containment zones
Pigment and chemical manufacturing thermal equipment
