Product Description

Our domain expertise has enabled us to render remarkable services of Chimney Boiler Refractive Lining. These service are provided for every chimney that lacks a masonry liner or has a cracked liner so as to avoid any kind of hazard. We use refractory material in this service to ensure longevity of chimney. High in demand, our range withstands the action of abrasive or corrosive solids, liquids or gases at high temperatures.


  • The process begins with a complete chimney sweep that removes soot, cake and any loose material

  • Deteriorated tile liners are removed too

  • This provides a solid base for the new lining

  • All stoves and heaters are then detached and the flue openings are temporarily sealed

  • One or more inflatable rubberized tubes are inserted so that they project from both the top and bottom of the chimney

  • Available standard tubes can form flues from 3 to 12 inches in diameter and from 3x5 to 6x11 inches, elliptical

  • Stainless steel spacer springs are placed around the tube form so that the flue will be centered in the void

  • Then the tube is inflated to create the properly size d opening for the flue

  • The rubber tubes tend to shorten as they expand to provide a uniform diameter throughout their length

  • When deflated later the tube returns to its original longer length, making it easier to break away from the chimney


  • Withstand high temperatures

  • Withstand sudden changes of temperatures

  • Withstand action of molten metal slag, glass, hot gases

  • Withstand load at service conditions

  • Withstand load and abrasive forces

  • Conserve heat

  • Have low coefficient of thermal expansion

  • Should not contaminate the material with which it comes into contact

Melting point:

  • Pure substances melt instantly at a specific temperature

  • Most refractory materials consist of particles bonded together that have high melting temperatures

  • At high temperatures, these particles melt and form slag

  • The melting point of the refractory is the temperature at which a test pyramid (cone) fails to support its own weight


  • The size and shape of the refractories is a part of the design of the furnace, since it affects the stability of the furnace structure

  • Accurate size is extremely important to properly fit the refractory shape inside the furnace and to minimize space between construction joints

Bulk density:

  • The bulk density is useful property of refractories, which is the amount of refractory material within a volume (kg/m3)

  • An increase in bulk density of a given refractory increases its volume stability, heat capacity and resistance to slag penetration
