FPSO (floating production storage tanker) and FLNG (floating liquefied natural gas installation system) are the main production methods in offshore oil and gas industry at present. Due to its special location and environment, there are many challenges in the construction, operation and maintenance of FPSO&FLNG. The characteristics of working conditions such as corrosion, high pressure, seawater and deep sea require that the valves used in FPSO and FLNG systems need to be specially designed and manufactured, using corrosion-resistant materials, seals and external special coatings.
