Characteristics and applications of Molybdenum tube
Molybdenum tube has high melting point,high strength,outstanding thermal conductivity,excellent resistance to thermal impact and corrosion,and can be used at service temperature up to 2000°C.
There are many uses of molybdenum thin walled seamless tube, for instance, applied as components of electron tubes,heaters of high temperature furnaces,thermocouple retainers,etc.

Special specifications can be customized according to customer requirements.
We has four kinds of method in manufacturing process of molybdenum tube: deep hole drilling, sintering, welding and stretching.
Deep hole drilling molybdenum pipe: punch the high-quality molybdenum rods by drilling machine. This method has a high cost and wastes molybdenum materials, but the mechanical properties are much better.
The process of sintering is mainly used to manufacture the large molybdenum tubes, such as smelting equipment, furnace tube, circular target material, vacuum heating chamber, etc. Compress the molybdenum powder in the mould by the isostatic pressing process, sintering under high temperature. And then polish the outer surface and inner surface of molybdenum tube through mechanical processing.
Welding molybdenum tube is mainly used for equipment spare parts which not strict with size. Rolling the molybdenum sheet into a tube, welding in vacuum, then proceed to roundness correction treatment.
The process of stretching is used in the production of small molybdenum tube. The technology is complex. Basically is stretching the common molybdenum tube by special equipment.
In order to avoid the molybdenum tube have any collision in transit or damage, usually wrapped with pearl cotton (expandable polyethylene), then packed into wooden case .To ensure the integrity of the product after delivery.
