Re: Joining Different Material In Steam Ducts
Here a product that you may want to investigate. I am not sure if it is available in your area. I will leave that research to you.

Have you try with polyurethane pipes ?

Re: Joining Different Material In Steam Ducts
Dear Sushanta,
We recommend a two-part ceamic-epoxy wearing compound.
For more details, please visit :

Your temperature range is no poblem for Eli-Cote FR1008LV.

Steam Ducts
We have great experience in coating duct/pipes against
corrosion upto 225 deg C.
The coating is applied over a shot blasted surface to a thickness
of 1mm.
The coating must be chemically fused to the sub straight @150
deg C. This is done by process gas or external heaters.
It comes in two derrivitives;
Corrosion resistant only,
Wear protection/corrosion resistant, with an integral micro filler
to give Alumina Ceramic type wear resistance.
The coating will also give a non stick surface therefore does not suffer with dew point enviroments. ■
Joining different material in steam ducts
We have a problem of corrosion in steam ducts, while cooling anodes going through the cooling tunnel in anode paste plant.
The anodes are being cooled by spraying water, while they are transferred through the tunnel. The steam generated is evacuated through the exhaust system.
Due to this the steam duct gets worn out and requires frequent replacement.
The temperature of the steam inside the duct goes maximum to 60 Deg. Centigrade.
Recently we have changed a part (almost half) by Galvanised steel, the rest need to be replaced.
We wanted any non metallic like HDPE, but came across from local manufacturer that the mateial can not take this high temperature on continuous basis.
Do any one have any other material suitable for this purpose.
We have an idea of changing the other portion by Aluminium, will it react (Cathodic Reaction) with GI Steel, even though if we provide some kind of rubberised flexible connection separating the joint.
Please advice.
Regards
