Introduction to the similarities and differences between FRP sand-filled pipes and FRP ventilation ducts

FRP sand-filled pipes and FRP ventilation ducts are both types of FRP pipe. They are made of glass fiber as the basic raw material. The manufacturers also use centrifugal casting, continuous winding, and fixed-length winding. The following introduces the similarities and differences between FRP sand-filled pipes and FRP ventilation ducts.
1. The application environment of the two is different
FRP ventilation ducts are mainly used in textiles, chemicals, printing, metallurgy, underground facilities, and other places where corrosive waste gas needs to be discharged. FRP sand-filled pipes are mainly used in the chemical industry, drainage projects, pipeline projects, etc.
2. The product characteristics of the two are different
The corrosion resistance of FRP sand-filled pipes is lower than that of FRP ventilation ducts. FRP ventilation ducts have extremely strong corrosion resistance and can be used for a long time even in corrosive environments.
