- JIS G3459: Japanese standard for stainless steel pipes.
- GB/T 12771 (China): Standard for fluid transportation stainless steel welded pipes.
2. Key Quality Requirements
- Material: Must meet 304, 316, 316L, 321, or other specified grades.
- Dimensions: Strict tolerance control on outer diameter (OD), wall thickness (WT), and length.
- Surface Finish: Smooth, burr-free, with options for polished, brushed, or pickled surfaces.
- Testing: Hydrostatic testing, eddy current testing, or ultrasonic testing (UT) for defect detection.
