Physical Properties

The physical properties of stainless steel grade 625 Capillary Pipe are tabulated below.

PHYSICAL PROPERTIES
Yield strength: ≥40,000 psi
Tensile strength: ≥100,000 psi

Capillary tubes with a maximum bore of 0.0158 in., available in a wide range of stainless steels. Alleima capillary tubes are characterized by tight tolerances, and the inside surface of the tubes is free from oil, grease and other particles. This ensures, for example, an optimized and even flow of liquids and gases from the sensor to the measuring instrument

SS CapillaryTube are widely used in making shock absorber, gas spring applications, tie rods, side impact beam, propeller shafts, stem steering system etc. It provides feature such as corrosion resistance, high strength, environmental free, etc.

Stainless Steel Capillary Pipe is very small internal diameter. It is coiled to several turns so that it could occupy less space and it has a very long continuous length. T direct s used to control the flow of refrigerant. It also connects the remote bulb to the thermostatic expansion valve or vice versa.

SS Capillary Tube Seamless is designed to change the high pressure liquid refrigerant into a low pressure spray of refrigerant. Its pressure drop amount is dependent on the length and inside diameter of the tube.

Stainless Steel Capillary Tube ,
Alloy 625 grade stainless steel.
Precise precut lengths.
Clean and smooth surface finish.
Color coded for easy identification.
Tight tolerance: OD and ID +/-0.001″.
Whether you need to replace system tubing as part of your troubleshooting or want to reduce the dwell volume of your system as you move to narrower columns, Restek has the quality tubing in the lengths and IDs you need. Each ID is color coded, so it is easy to identify and replace correctly.
Tubing is precision cut, resulting in clean, square-cut ends without ovality.
