4. Manufacture Process

The production process of molybdenum tube is roughly as follows:

1) Raw material preparation: select high-purity molybdenum metal powder as raw material, and carry out sieving, drying, and other treatments.

2) Pre-compression: Put molybdenum metal powder into the mold and perform slight compression to give it a certain shape and stability.

3) Sintering: Put the pre-pressed molybdenum material into a high-temperature heat treatment furnace to form a high-density sintered body through heat treatment.

4) External processing: processing the sintered body, such as cutting, grinding, polishing, etc., to make the pipe shape that meets the requirements.

5) Internal processing: processing inside the tungsten tube, such as drilling, reaming, etc., to achieve more precise size and surface requirements.

6) Cleaning: The finished tungsten tube is cleaned to remove surface dirt and impurities and ensure its high purity.

7) Inspection: Quality inspection of finished tungsten tubes, such as appearance, size, mechanical properties, and other indicators, to ensure that the product quality meets the standards.

8) Packaging: Packaging and labeling qualified finished tungsten tubes to facilitate storage, transportation, and use.

5. Working Principle

Molybdenum tube is a tube made of pure molybdenum with high temperature, high hardness, and high corrosion resistance. Molybdenum has very good thermal and chemical stability at high temperatures, so molybdenum pipes are often used in high-temperature smelting, vacuum equipment, rocket engine nozzles, and other fields.

The working principle of molybdenum metal tubes is mainly based on the high temperature and high hardness of molybdenum. It can withstand high temperatures and high pressure and has excellent thermal conductivity and electrical conductivity, so when used under high-temperature conditions, molybdenum pipe can maintain good mechanical properties and structural stability. At the same time, molybdenum pipes also have excellent corrosion resistance and can work in harsh environments such as strong acids and alkalis, so they are widely used in chemical, energy, aerospace, and other fields.

6. Application Fields

Molybdenum pipes can be used in a variety of fields, including:

1) Semiconductor industry: It is used in semiconductor production to manufacture insulating materials and support and fix various high-temperature areas.

2) Chemical industry: It is used in chemical reactors to make electrodes, heat exchangers, and heaters.

3) Medical equipment: It is often used as X-ray target materials in medical equipment and other medical equipment.

4) Aerospace industry: It is widely used in conducting high-temperature tests, satellite and rocket propulsion systems, and other aerospace equipment.

5) Vacuum equipment: It is widely used in the manufacture of vacuum devices, such as high vacuum bulbs, vacuum containers, vacuum pipes, etc.

7. Package and Shipment

Regarding packaging and transportation, molybdenum tube is usually packed in wooden boxes, wooden boxes or steel drums, and can be shipped by sea or air.
