Ceramic Gland Packings

Square Ceramic packing has great flexibility and mechanical resistance and can withstand continuous temperatures of up to 650°C (glass fibre reinforced) or 1050°C (Inconel reinforced). The product contains around 20% organic binders to aid in the carding process. The binders burn at low temperatures but have no influence on the unique ceramic fibers. On request, it can be impregnated with graphite to improve lubrication.

Ceramic Gland Packing

Features :

  • Non-hazardous heat resistant fiber construction
  • 1000°C for constant duties, with excursions to 1100°C
  • Competitively priced alternative to normal ceramic fiber packings
  • Far better value for money than other non-hazardous high temperature materials, such as those made of pure silica fiber
  • Good chemical compatibility

Materials :

General specification
Applications: Sealing joints in boilers, industrial furnaces, oven doors, coke furnaces.
Characteristics: Excellent chemical stability resisting attack from most corrosive agents.
Exceptions are fluorides, phosphoric acids and concentrated alkalis.
Chemical analysis of square ceramic packings:
  • Aluminium oxide AL2O3 45-48%
  • Silicon oxide SiO2 51-55%
  • Iron oxide Fe203 0,7-1,2%
    		•
    Temperature resistance °С up to 650°C (glass-fibre reinforced) or up to 1050°C (Inconel reinforced)

    People also ask

    • What is the temperature range of ceramic packing?
    • The ceramic fibre itself is rated to 1260°C in optimum conditions, but the organic content will burn off at 200°C and so it should be noted that ceramic packing might 'flash flame' on first application.
    • What is the best material for packing glands?
    • PTFE (polytetrafluoroethylene) compression packing are widely used due its resistance to chemical attack, low coefficient of friction and wide temperature.
    • Can ceramic crack from heat?
    • On the other hand, naturally brittle materials like glass, porcelain, and ceramic are more likely to crack or even shatter in response to sudden temperature changes, which is why most manufacturers advise letting a freshly-baked pie cool down before putting it in the fridge.
    • Does ceramic contain iron?
    • material without some iron—it's found in almost everything from feldspars to kaolin to ball clays, earthenware clays, and many colorants.
