Seamless Mo Molybdenum Alloy Pipe Tube for high temperature furnaces

Product Description

Molybdenum tube refers to a type of high-purity molybdenum metal tube made by melting or sintering high-purity molybdenum powder into molybdenum rod billets, and then undergoing a series of processes such as forging, rolling, and machining. According to different wall thicknesses, molybdenum pipes can be divided into seamless thin-walled molybdenum pipes and conventional molybdenum tubes.

We have 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.

 

Application

Molybdenum tubes are widely used in electric vacuum industry. It also can be used as high temperature environment cooling tube, heating tube, high temperature environment protection tube, etc. Large molybdenum tube can be used as circular target material etc. small molybdenum tubes are used as instrument parts.
