Frequently Asked Questions (FAQ)

What standards do your stainless steel coil tubes comply with?

Our stainless steel coil tubes are manufactured in compliance with major international standards, including ASTM A-312, ASTM A-269, ASTM A-632, ASTM A-213, DIN 17458, DIN 17456, and JIS G3463/G3459/G3448.

What are the available material grades for these coil tubes?

We supply products in multiple material grades, including standard Austenitic grades such as 201, 202, 304, 304L, 310S, 316, 316L, 317L, 321, 347, and duplex grades like UNS S31803 and UNS S32750.

What size ranges do you offer for stainless steel precision coiled tubing?

Our outer diameter (OD) ranges from 0.1mm to 8mm, with wall thicknesses spanning from 0.05mm to 2.1mm. Lengths can be customized to 2440mm, 3050mm, 5800mm, 6000mm, 6100mm, or tailored to customer requests.

How is the quality of the control line tubing ensured?

Quality is maintained through a combination of controlled manufacturing and finished product tests. These include non-destructive tests, hydrostatic testing, surface finish inspections, dimensional checks, flare/coning tests, and mechanical/chemical analysis.

What surface treatments are available for stainless steel coil tubing?

We provide Bright Annealed (BA) finish as well as polished inside and outside surfaces. Polishing specs include Satin/Hairline (180#, 320#) and high polish finishes (400#, 600#, 800# or Mirror finish).

What are the typical applications for precision capillary tubes?

Capillary tubes are widely used in medical devices, temperature sensors and industrial controls, instrumentation, electronic micro-tubes, car antennas, laser engraving setups, and high-precision dispensing equipment.
