5. FAQ
Q1: What is the difference between 304 and 316 stainless steel welded pipe?
A1: 316 contains molybdenum element, better acid resistance, salt corrosion resistance and high temperature resistance than 304. 304 is for general corrosive environment; 316 is more suitable for marine, chemical, pharmaceutical and coastal projects.
Q2: Can you provide customized size and length?
A2: Yes. We support custom outer diameter, wall thickness, fixed length, surface finish and special end processing according to customer drawings.
Q3: Do you provide Mill Test Certificate and inspection report?
A3: Absolutely. Each batch is attached with official MTC, SGS/BV test report, PMI certificate for customs clearance and project acceptance.
Q4: What is your MOQ?
A4: Small trial order is acceptable. Regular MOQ is 1 ton; stock goods can support mixed container loading.
Q5: How to guarantee the product quality?
A5: Strict raw material incoming inspection → online weld quality control → hydraulic & eddy current pressure test → full dimension inspection → before shipment recheck. Third-party inspection is welcomed.
Q6: What payment terms do you accept?
A6: T/T, L/C at sight, Western Union, Trade Assurance. Flexible payment for long-term cooperation clients.
