What is precision tube?

Precision tube is a high-precision, high-brightness seamless pipe produced by cold drawing or cold rolling. It is one of the combustion devices made of special materials. Due to its high dimensional accuracy, strong corrosion resistance, and high temperature resistance, it is widely used in thermal control, specific gravity meter, gas generator and other fields in high-temperature smelting process.

Classification of precision tubes

According to the different materials of precision tubes, they can be divided into three types, namely tungsten precision tubes, molybdenum precision tubes and tantalum precision tubes.

1. Tungsten precision tube

Tungsten precision tube is made of tungsten material, which can withstand high temperature up to 4000℃, has high hardness and high melting point, and is widely used in distillation, electronic processing and other fields.

2. Molybdenum precision tube

Molybdenum precision tube is made of molybdenum material, which can withstand high temperature up to 3000℃, has good wear resistance and strong chemical stability, and is used in semiconductors, high-temperature smelting and other fields.

3. Tantalum precision tube

Tantalum precision tube is made of tantalum material, which can withstand high temperature up to 2400℃. It has good corrosion resistance and good welding performance. It is widely used in chemical industry, medical field and other fields.

Application fields of precision tube

The high precision and high stability of precision tube make its application field very wide. Here are several main application fields.

1. Thermal control

Precision tube can maintain stable performance in high temperature environment, so it is widely used in thermal control system, such as furnace temperature control in high temperature smelting process, control of high temperature gas generator, etc.

2. Hydrometer
