Tungsten Tube/Pipe

The Tungsten Tube, also called tungsten pipe, is made from high-purity tungsten metal. It has an extremely high melting point (3422 ℃) and excellent corrosion resistance and is widely used in industries requiring high-temperature or high-pressure applications. Shanghai Yuepeng can provide custom sizes, shapes, and compositions to meet specific demands.

Tungsten Tube/Pipe Production Process

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

Tungsten Tube/Pipe Processing Method

• Sintering
• Forging
• Rotary Forging
• Rolling
• Polishing

Tungsten Tube/Pipe Surface Treatment

Depending on the intended applications, tungsten 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 dimension control.

Tungsten Tube/Pipe Applications

• High-temperature Furnace: Tungsten Tubes are mainly used for thermocouple protection tubes in high-temperature furnaces, sapphire crystals, and support parts for high-temperature sintering furnaces.
• Medical: Due to it has good radiation shielding effect, tungsten tubes can be used as shielding strings in medical treatment.
• Aerospace: Because of its good high-temperature resistance, tungsten tubes are also commonly used in the lining components of rocket engines and ignition tube components.

Tungsten Tube/Pipe Packaging

The Tungsten Tube/Pipe is 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.
