Introduction
Niobium tubes are specialised pipes designed for conveying and transferring materials under extreme conditions, such as high temperature and high pressure. They are widely used in nuclear energy, aerospace, shipbuilding, chemical processing, and electronics.
Niobium’s excellent corrosion resistance and high-temperature stability make these tubes capable of withstanding compressive, tensile, fatigue, and thermal stress, making them ideal for high-end industrial applications.
The surface of niobium tubes can be treated using various methods to enhance corrosion resistance, cleanliness, and surface finish:
Mechanical Polishing – improves surface flatness and finish.
Electrolytic Polishing – enhances smoothness and corrosion resistance.
Pickling – removes oxides and impurities for a clean surface.
Sandblasting – ensures uniform surface texture and removes contaminants.
