They are responsible for connecting various pipelines inside and outside the hull to ensure the smooth flow of fluids such as seawater, fresh water, fuel, lubricating oil and exhaust gas. These pipe fittings must not only withstand the complex and changeable environmental pressure at sea, but also have to have good corrosion resistance, vibration resistance and sealing properties. Ship pipe fittings usually need to be sprayed with a protective layer on the surface during production, and some special pipes are usually also sprayed inside. Therefore, a spraying device is required.
