Stainless steel capillary and stainless steel small tubes are widely used in medical treatment, fiber-optic, pen making, electronic welding products, light cable joint, food, vintage, dairy, drink, pharmacy, and biochemistry. Different lengths can be provided according to specific requests.

Capillary tubes with a maximum bore of 0.0158 in. are available in a wide range of stainless steels. Our 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.

Stainless steel coiled tubing is available in a range of different product forms depending on customer requirements. We manufacture welded and seamless tube products. The standard grades are 304, 304L, 316L (UNS S31603), Duplex 2205 (UNS S32205 & S31803), Super Duplex 2507 (UNS S32750), Incoloy 825 (UNS N08825), and Inconel 625 (UNS N06625). Other grades of stainless steel in duplex, super duplex, and nickel alloys are available on request.

Diameter ranges from 3mm (0.118’’) to 25.4mm (1.00’’) OD. Wall thickness ranges from 0.5mm (0.020’’) to 3mm (0.118’’). Tubing can be supplied in the annealed or cold-worked stainless steel control line pipe condition.

Frequently Asked Questions (FAQ)

What steel grades are available for your coiled tubing?
We manufacture coiled tubing in standard grades such as 304, 304L, 316L, Duplex 2205, Super Duplex 2507, Incoloy 825, and Inconel 625. Other duplex, superduplex, and nickel alloy grades are available upon request.
What dimensions can you supply for stainless steel coiled tubing?
Our coiled tubing is available in outer diameters (OD) ranging from 3mm (0.118’’) to 25.4mm (1.00’’), and wall thicknesses from 0.5mm (0.020’’) to 3mm (0.118’’).
How is the inside surface quality of the capillary tubes ensured?
The inside surfaces of our precision capillary tubes are kept completely free from oil, grease, and other particles. This guarantees tight tolerances and an optimized, consistent flow of gases or liquids.
What quality tests do your control line tubes undergo?
We perform comprehensive quality testing on our products, including non-destructive testing, hydrostatic testing, surface finish control, dimensional accuracy checks, flare & coning tests, and full mechanical/chemical property evaluations.
What is the standard packaging and length for coiled tubes?
We typically package coiled tubing in woven bags or plastic bags. Lengths range from 200m to 1500m per coil, and we can also customize lengths to fit specific customer requirements.
