Cast iron and concrete are only two examples of the various materials that glass fiber-reinforced polymers (GFRP) are a strong substitute for. It is distinguished by having strong erosion and corrosion resistance and high corrosion resistance. Commercial GRP was utilized in erosion and corrosion tests. It is well-known for being installed in the severe environment of petroleum fields' effluent. This kind of GRP material was put through a simulation of an inclement, or severe, climate. A large number of experiments were conducted: fifteen liters of water were mixed with four different amounts of abrasive sand (200 gm, 250 gm, 300 gm, and 350 mg) of 65 µm diameter. The resulting mixture of abrasive agents is struck by GRP samples that were taken from the walls of cylinder pipes at three different angles—85, 90, and 95 degrees—as well as two different flow rate conditions. Also, the effect of the diameter of the nozzle from which the fluid is projected is investigated by using three different nozzle diameters: 0.25, 0.375, and 0.5 inch The effect was also investigated when a 5% weight of chlorine was added to the sample. Additionally, the same tests were run for one, two, three, and four hours at different times. The amount of abrasive sand and the flowrate both increased the erosion rate, according to the results. The amount of weight loss, which served as an indication of erosion activity, was shown to have a significant impact on the corrosion rate. Therefore, in hostile environments or in situ situations, GRP provided higher erosion and corrosion protection than traditional materials.
