Frequently Asked Questions (FAQ)

What are the primary applications of 316 stainless steel pipes?

Due to their exceptional corrosion resistance and mechanical strength, 316 stainless steel pipes are widely used in fluid transportation (oil, gas, water, steam), heat exchangers, boilers, medical devices, sensors, hydraulic pneumatic components, and instrumentation systems.

What standards do your stainless steel pipes comply with?

Our pipes are manufactured in strict compliance with major international 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.

What are the typical size tolerances for these pipes?

The standard tolerances are: Outer Diameter: +/- 0.2mm; Thickness: +/- 10% (or as requested by the customer); Length: +/- 10mm.

What surface finishes and polishes can be provided?

We offer Satin / Hairline finishes (180#, 320#) and multiple Polished finishes (400#, 600#, 800#, or Mirror surface) depending on your design and application requirements.

What tests are performed to ensure product quality?

Every batch undergoes standard quality controls, including Non-destructive testing, Hydrostatic testing, Surface finish inspection, Dimensional accuracy measurement, Flare/coning tests, and full Chemical/Mechanical property assessments.

How are the tubes packaged for delivery?

Tubes are typically packed in plastic bags or woven wrapping. Specialized packaging requirements can also be accommodated based on specific customer requests.
