Stainless steel capillary tube is a slender pipe made of stainless steel material. It has a variety of excellent properties and is widely used in various fields.
Stainless steel capillary pipe are made of high-quality stainless steel materials, such as 304, 316, etc. These stainless steel materials have excellent corrosion resistance, high temperature resistance and mechanical strength. This enables stainless steel capillary tubes to adapt to various complex environmental conditions, including corrosive liquids such as acids and alkalis.
The diameter of stainless steel Capillary Tubing is usually small, generally in the millimeter level, and the wall thickness is also relatively thin. The diameter of stainless steel capillary tubes is usually between 0.1 mm and 1 mm. It is an ultra-thin tube product with a small cross-sectional area. Due to the small diameter of the pipe, the wall of the stainless steel capillary tube is also very thin, usually between 0.01 mm and 0.1 mm, to ensure a certain mechanical strength. This design allows the capillary tube to have sufficient channel size while ensuring smooth pipe flow and low resistance.
stainless steel round capillary tube have thin walls and soft materials, so they are easy to be bent and formed by a pipe bender, but the bending radius cannot be too small, otherwise the tube wall will easily deform.
Austenitic Stainless Steel Capillary Tubes are widely used in many fields. Due to their excellent flow characteristics and high precision, stainless steel capillaries are indispensable in analytical techniques such as liquid chromatography and capillary electrophoresis. In addition, it can also be used to transport small flows of liquid or gas, such as fluid control and delivery in microfluidic systems.

SS Capillary Tubes
Heat treatment (annealing) of stainless steel capillary tubes
For 304/304L stainless steel, it cannot be hardened by heat treatment itself. But its tensile strength and hardness can be enhanced through cold working, such as stretching, bending or twisting. When it comes to annealing, the temperature is typically set between 1850°F and 2050°F. The main purpose of annealing is to soften the material and improve its plasticity. But importantly, because this material is prone to oxidation at high temperatures, it needs to be cooled quickly. For heavier parts, water cooling is recommended, while for lighter parts, air cooling is recommended.
