Heat resistance temperature of fiberglass-reinforced plastic equipment in the sulfuric acid industry
Thread Content
What is the maximum operating temperature in the sulfuric acid industry for fiberglass-reinforced plastic equipment, in order to extend its service life?

Ethylene resin: above 85 degrees; high-performance variants can withstand up to 450 degrees. 3. Unsaturated resin: around 65 degrees
It seems that fiberglass-reinforced plastic is largely resistant to corrosion by various media; temperature has a significant impact on it, and I recall that temperatures below 100°C have little effect on its lifespan
It is best not to exceed 85°C, otherwise the resin will age
Also, there are many things that can corrode fiberglass-reinforced plastic, such as alkalis and chlorine water; we have replaced many of our fiberglass-reinforced plastic equipment.
Temperatures below 80 degrees are safer; it also depends on the adhesive used in construction – if high standards are required, fiberglass is not suitable
