METZ Carbon Bricks

Description

Owing to its chemical inertness, and ability to be produced to close dimensional tolerances, carbon is an ideal material for lining process vessels where severe chemical or physical operating conditions are encountered. Carbon brick linings are used exclusively where fluorides and hydrofluoric acid are encountered, due to their ability to resist chemical attack from fluoride solutions – for example, phosphoric acid production.

Features

  • Chemical Resistance
    Resistance to practically all corrosive inorganic chemicals, except those which are strongly oxidising, such as oleum, concentrated chromic acid and concentrated nitric.
    Will resist concentrated boiling hydrofluoric acid.
  • Inert
    Chemically inert. Will not taint or influence the composition of chemicals in contact with the lining.
  • Thermal Shock Resistance
    Will withstand damage due to sudden change in temperature.
  • High Temperature Resistance
    Can be used in most chemical processes where temperature is below 400ºC. Above this temperature, strict control of atmospheric conditions must be enforced to ensure that the atmosphere is either reducing or neutral.

Uses

  • Phosphoric Acid manufacturing plants
  • Alkaline Pulp digesters – Pulp and Paper Industry
  • Humidifying Towers – Sulphuric Acid manufacturing plants
  • Stainless Steel Pickling Plants – utilising Hydrofluoric and/or Nitric acids.
  • Benzene and Naphthalene washing plants.
