Self-supporting Steel Chimney

Sleeve self-standing anticorrosive steel chimney is an invention patent of Rainbow, sleeve structure is mainly composed of outer cylinder, inner cylinder, heat insulation layer, air layer. The outer cylinder supports the cylinder part and resists atmospheric corrosion; The inner cylinder has the function of smoke exhaust and anti-corrosion; The heat insulation layer is to control the flue gas temperature does not transfer to the outer cylinder, avoid condensation on the wall of the cylinder, and stabilize the flue gas flow rate and temperature of the inner cylinder; The air layer is the second insulation line, and provides space for axial displacement to prevent huge thermal expansion force from damaging the inner cylinder.

Each steel chimney is designed according to the customer`s special requirements and demands, and the design is based on the national standards in force and the project specifications.
