Advantages
1.The flue applies in any kinds of building for exhausting gas and smoke. It has advantages by use the GRC materials, like high strength, fireproof and light weight on installation, etc. 2.The size can be adjusted according to the height between each floor and the amount of the gas exhausted. Exhaust Gas Passage With Variable Pressure with double tubes, to avoid the phenomenon of foul air from floor to floor, it’s anti-downdraught; check valve is added at the joint. 3.The flue pipes applies for any height between the floors, It can bear the weight by layered installation. 4.Measure the height between external pipe and the roof according to the designs.
