Frequently Asked Questions (FAQ)

What size ranges are available for stainless steel capillary tubes?

Our capillary tubing is available in outer diameters (OD) ranging from 0.25mm up to 28mm, and wall thicknesses from 0.08mm up to 1.5mm. We can accommodate custom sizing requirements within this range.

Which stainless steel grades do you supply?

We supply a comprehensive list of grades, including standard grades like 201, 304, 304L, 316, and 316L. We also provide specialty and high-alloy grades such as 904L, 310s, duplex 2205, super duplex 2507, and nickel alloys like Inconel 625 and Incoloy 825.

Can capillary tubes be supplied in long continuous coils?

Yes, we specialize in manufacturing long continuous coils without any welded joints, with lengths ranging from 600 to 3500 meters per coil. We also supply straight cut-to-length tubes depending on your application requirements.

What types of testing and quality inspections are performed?

To guarantee the highest quality and safety, all our capillary tubes undergo strict inspections, including Chemical Composition verification, Physical Properties analysis, Eddy Current Testing, and Hydrostatic (Hydro) Testing.

What are the primary applications of stainless steel capillary tubes?

Capillary tubes are widely used for dynamic instrument signal transmission, automatic instrument wire protection, precision optical rulers, industrial sensors, electronic equipment protection, thermal instrument capillary systems, and inner support structures for high-voltage cables.

What surface finish is provided on the tubes?

Our stainless steel capillary tubes are supplied with a bright and soft annealed surface finish, which ensures optimal flexibility, smooth inner/outer surfaces, and excellent corrosion resistance.
