Comparison of carbon steel lined with rubber or FRP
Thread Content
Either rubber lining or FRP lining made of carbon steel can be used. Let’s compare which one is more suitable (in terms of price, construction, etc.)
It depends on which side you will use it on, as well as what requirements you have regarding corrosion resistance. The cost of lining with rubber is much higher than that of FRP, and in terms of construction process, the time required to apply a rubber lining is also relatively longer. However, rubber-lined versions are clearly much more durable than FRP ones.
What medium is inside the device? However, I think that given the good quality of the rubber lining, pre-vulcanized butyl rubber could be considered as an option. It can be applied right after sandblasting and rust removal, and the installation speed is not slower than that of fiberglass linings; once applied, it’s ready for use. The price is just a little higher than that of fiberglass linings
The price of fiberglass lining is generally lower than that of rubber lining, and the construction difficulty is also lower； The quality of rubber linings is generally better than that of fiberglass-reinforced linings. Both their quality and price are related to the specific bonding process and the type of bonding material used. It should be selected based on the corrosive environment of the equipment and its usage conditions.
It mainly depends on what type of medium is involved; lining with rubber isn’t a solution that works for all types of media. With the advancements in material technology, the corrosion resistance of FRP is also improving, and it offers many advantages in terms of construction (it can be shaped into various forms and used to create small devices, etc.). Generally, rubber sheets are more expensive, but high-quality FRP materials aren’t cheap either.
