Niobium Tube/Pipe Production Process

Raw Material: Select high-purity niobium powder.
Powder Metallurgy: Mix with binder and compact into a green billet.
Sintering: High-temperature sintering to remove the binder and increase density.
Drawing: Draw the rod to achieve the desired size and finish.
Heat Treatment: Anneal to relieve stress and enhance properties.
Surface Treatment: Clean and polish the surface.
Cutting & Customization: Cut or customize according to requirements.

Sintering
Forging
Rotary Forging
Rolling
Polishing

Niobium Tube/Pipe Surface Finish

Depending on the intended applications, niobium tubes and pipes have three main surface finishes as follows:

Black: The surface is “as swaged” or “as drawn”, retaining a coating of processing lubricants and oxides.
Cleaned: The surface is chemically cleaned to remove all lubricants and oxides.
Ground: The surface is centerless ground to remove all coating and to achieve precise dimensions control.

Niobium Tube/Pipe Applications

Superconducting Technology: Niobium tubes and pipes can be used in superconducting magnets, such as in MRI machines and particle accelerators.
Aerospace: Niobium tubes and pipes can be applied in engine components and rocket nozzles due to their high temperature and corrosion resistance.
Nuclear Energy: Niobium tubes and pipes are used in fuel cladding and high-temperature components in nuclear reactors.
Chemical Industry: Niobium tubes and pipes can be employed in reactors and pipelines in highly corrosive environments, such as acidic or alkaline conditions.
Electronics: Niobium tubes and pipes can be used in high-end electronic devices for superconducting materials.
Niobium Capillary Tube: Niobium capillary tubes are often used in high-pressure sodium lamp production.

Niobium Tube/Pipe Packaging

The Niobium Tube and Niobium Pipe are carefully placed in wooden cases or cartons with additional support from soft materials to prevent any shifting during transportation. This packaging method guarantees the integrity of the products throughout the delivery process.
