Various Uses Of Vacuum Pin Tubes

Posted by Admin on September, 13, 2013

Vacuum Pin Tube, also known as Evacuated Pin Tube, is used for collecting samples of molten material for the purpose of hydrogen analysis. Vacuum Pin Tubes are fabricated from borosilicate glass, and the wall thickness stays approximately 0.5 mm. Both the ends of the tube are sealed. The following section elaborates on how exactly the Vacuum Pin Tubes work.

How Do Vacuum Pin Tubes Work?

The characteristic feature of a Vacuum Pin Tube is the thin, approximately 1 mm., wall bulb section. When the tube is brought in contact with the molten sample such as gold, silver, steel, iron etc, the bulb melts and allows the fluid to enter into the tube. This results in the formation of a solid, slag-free pin.

The process described above involves the use of a simple spring holder that holds the Evacuated Pin Tube. It is the requirement of the process that tube be inserted into the molten metal precisely at an angle of 45°. Special care is taken for ensuring the same.

Vacuum Pin Tubes are available in varying volumetric capacity as well. For example, you can select tubes that can section half a gram or 1 gram of the sample from the pins. It is quite clear that Evacuated Pin Tubes are a simple apparatus for rapid sampling of molten metal.
