Fiberglass piping is extensively used in fields such as oil, thermal power, chemical industry, urban water supply and drainage, factory wastewater treatment, seawater desalination, gas transmission, and coal mine ventilation. Known for its excellent corrosion resistance, smooth inner surface, low energy consumption during transportation, long service life, light weight, easy transportation and installation, and no need for additional anti-corrosion treatment like metal or concrete pipes, it offers a low overall cost and is increasingly accepted by a wide range of users.
