The main differences between fiberglass pipes and plastic pipes:
Material Differences
Fiberglass pipes are made of resin (such as polyester, epoxy, etc.) and glass fiber, belonging to composite materials; plastic pipes are mostly made of high molecular polymers (such as PP, PVDF, etc.), belonging to single materials.
Performance Comparison
Corrosion Resistance: Fiberglass pipes have stronger resistance to corrosive media such as acids, alkalis, and salts, and are especially suitable for harsh environments such as chemical plants; plastic pipes have weaker corrosion resistance and are easily corroded by acids and alkalis.
Strength and Stiffness: Fiberglass pipes have better impact resistance and pressure bearing capacity than plastic pipes and can withstand greater external forces; plastic pipes have better toughness but are prone to deformation or breakage.
Temperature Resistance: Fiberglass has limited long-term temperature resistance (generally ≤120°C) and softens easily at high temperatures; plastic pipes have poor temperature resistance and are prone to aging at high temperatures.
Service Life: Fiberglass pipes have a longer service life due to their strong corrosion resistance; plastic pipes need frequent replacement due to aging.
