Frequently Asked Questions (FAQ)
What are the primary applications for 304 grade precision stainless steel pipes?
304 grade precision pipes are widely used in building, engineering, and manufacturing industries. They are ideal for conveying fluids (oil, gas, water, steam), heat exchangers, mechanical machinery, temperature sensors, medical devices, antennas, and various precision structural systems.
What size ranges and tolerances are available for these precision tubes?
We support outer diameters from 0.1mm to 8mm and thicknesses from 0.05mm to 2.1mm. Standard length configurations include 2440mm, 3050mm, 5800mm, 6000mm, and 6100mm, with custom sizes available. The typical tolerance range is +/- 0.2mm for outer diameters and +/- 10% for wall thickness.
What surface finish configurations can be ordered?
Tubes can be finished with Satin/Hairline (180#, 320#) or polished (400#, 600#, 800#) to a mirror finish. Bright annealed treatments are also available for both interior and exterior surfaces.
How is the quality of these precision tubes verified?
Quality is strictly monitored via a series of finished-product tests, including Non-destructive testing, Hydrostatic tests, surface finish controls, dimensional accuracy measurements, flare and coning tests, and comprehensive mechanical and chemical property analyses.
What standards do these stainless steel pipes comply with?
The precision pipes comply with a wide variety of global standards, including ASTM A-312, ASTM A-269, ASTM A-632, ASTM A-213, DIN 17458, DIN 17456, JIS G3463, JIS G3459, and JIS G3448.
