Frequently Asked Questions (FAQ)

What are the primary material grades available for coiled tubing?

We offer a wide selection of grades, including standard Austenitic grades like 304, 304L, 316, 316L, 321, 347, and high-performance options like Alloy 825, 904L, UNS31803, and UNS32760.

What sizing limits apply to your precision capillary tubes?

Our precision capillary tubes are manufactured with outer diameters (OD) spanning from 0.1mm to 8mm, and wall thicknesses ranging from 0.05mm to 2.1mm. Lengths can be customized to match your project specifications.

What certifications and manufacturing standards do the tubes meet?

Our manufacturing processes comply with key international standards including ASTM A-312, ASTM A-269, ASTM A-632, ASTM A-213, DIN 17458/17456, and JIS G3463/G3459/G3448.

Which quality inspection procedures do you implement?

Every batch goes through strict verification steps, including non-destructive testing (NDT), hydrostatic tests, dimensional accuracy checking, surface finish controls, flare and coning tests, alongside mechanical and chemical property analyses.

What options do you offer for surface finishing?

We supply custom surface finishes to suit industrial requirements, including Satin/Hairline (180# and 320#), and Polish configurations (400#, 600#, 800#) up to a bright mirror finish.

Are these tubes suitable for high-corrosion environments?

Yes. High-performance alloys like Alloy 825 feature balanced additions of Nickel, Chromium, Molybdenum, and Titanium, which deliver outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking in severe environments.
