FAQ
Q: What is the difference between metric and imperial 304 stainless steel pipes?
A: Metric 304 stainless steel pipes are measured in millimeters and follow ISO/EN standards, with the outer diameter directly corresponding to the nominal diameter; imperial pipes are measured in inches and follow ASTM standards, with the outer diameter corresponding to inches but the inner diameter determined by the wall thickness.
Q: Do you have quality control?
A: Yes, we have obtained BV and SGS certification.
Q: Can you arrange shipment?
A: Of course, we have a fixed freight forwarder, can get the best price from most shipping companies, and provide professional service.
