Stainless Steel Capillary Tube/ Tubo capilar de acero inoxidable
A tube with a very thin inner diameter is called a capillary tube. Usually refers to the inner diameter is equal to or less than 1 mm of thin tube, because some of the diameter as fine as hair, so called capillary. At present, it can be seen in medicine and building materials.
Application: The capillary tube is used for signal tube and wire protection tube of automatic instrument; precision optical ruler circuit, industrial sensor and electronic equipment circuit protection tube; safety protection of electrical circuit, protection of thermal instrument capillary tube and inner support of hollow high voltage optical cable.
Main Standard: ASTM A632
Main Grade: 304, 316L; 1.4301, 1.4404
Outer Diameter: 1-4.7mm
Wall Thickness: 0.1-1mm
Length: as customers’ requirement

How is it Measured? Outer Diameter (A) X Schedule or Wall Thickness (B) X Length
PS: 304 VS 316L
| 304 benefits | 316L benefits |
| Lower cost | Superior corrosion |
| Easier to weld and form | Stronger and more durable |
| Able to withstand corrosion from most oxidizing acids | Better for marine, offshore and washdown applications |
