Frequently Asked Questions (FAQ)
Q1: What are the main applications of ASTM A-312 stainless steel precision pipes?
A1: These precision pipes are widely utilized for fluid conveyance (such as oil, gas, water, and steam), heat exchangers, mechanical engineering applications, medical devices, precision sensors, capillary antennas, and decorative fittings like handrails and railings.
Q2: Which material grades are available for these precision tubes?
A2: The standard material grades available include 201, 202, 304, 304L, 310S, 316, 316L, and higher performance duplex grades such as S31803 and S32750 depending on specifications.
Q3: What are the outer diameter and thickness ranges for the stainless steel capillary tubes?
A3: The outer diameter ranges from 0.1mm to 8mm, and the wall thickness ranges from 0.05mm to 2.1mm, ensuring precise specifications for micro-diameter and high-precision applications.
Q4: What surface finishes and polishing levels can be provided?
A4: We offer satin and hairline finishes (180# and 320#), bright annealed (BA) finishes, as well as highly polished mirror surfaces (400#, 600#, and 800#) for both inside and outside surfaces.
Q5: How is the quality control and product testing managed for these tubes?
A5: Quality is maintained via strict production controls and finished product testing, including non-destructive testing (NDT), hydrostatic tests, surface finish inspections, dimensional accuracy checks, flare and coning tests, and full mechanical/chemical property verifications.
Q6: What packaging standards are used to prevent damage during transit?
A6: Tubes are typically packed in protective plastic bags, woven knitting strip bundles, secure wooden boxes, or heavy-duty steel boxes to safeguard against surface scratches and bending during transport.
