Chimney Ducts Pipe


Transferring hot air and chemicals through a fireplace flue is heavy-duty work.The use of improper Chimney Ducts can lead to complications such as fire hazards, structural damage to the Chimney, and hazardous materials and fumes coming back into the building To handle the high temperature operating conditions, we recommend using heat resistant a stainless steel or an aluminum Chimney Ducts At ENVIRO TECH, we have multiple Flexible Chimney Pipe options to provide you with the necessary tools for safe and effective operation.


Corrosion is a serious issue that significantly reduces the lifespan of a fireplace flue. Fortunately, stainless steel and aluminum resist corrosion damage caused by moisture, chemicals, and fumes.Our stainless steel Chimney Ducts are an excellent long-term investment because they are resistant to chemicals and materials that would cause severe damage to clay and brick Chimney Ducts Along with great resistance to corrosive materials, the stainless steel construction of some our hose materials is heat resistant up to 1650 degrees Fahrenheit.

Flexible Aluminium Ducting Hose


With rich expertise, we offer our clients a wide range of Aluminum Flexible Duct Pipe which is constructed using special aluminum alloy. These prevents our product from corrosion and metal fatigue. The fabrication of our machines help us in producing a continuous lock seam. This allows the duct to be pulled open, compressed, bent and re-bent without any leakage. Further, these results in not being dry rot when heat aged. These can be installed with severe bends. Apart from this, these can also be installed in unlimited lengths while maintaining an unrestricted diameter. Our range is conveniently boxed in 5 foot, 10 foot and 15 foot lengths. It is compressed to nearly 3 times its original length. This ensures convenient shipping and handling.




Aluminum Flexible Ducting can be used in the following Applications:

Heating air Conditioning


Fresh Air Intakes

Ideal for use in clothes dryer, bathroom and kitchen exhausts


Features Benefits:


Totally non-combustible Maximum operating temperature 435ºF
