Now there are many stainless steel seamless tubes on the market, Zhejiang stainless steel tubes produced by different manufacturers have different product quality, so how should we judge the quality of stainless steel seamless tubes when purchasing?

Generally good thick-walled stainless steel pipe will not have folds or cracks, and the surface of the steel pipe will not have pits, nor will it be easily cracked or scratched. A good steel pipe has an obvious metallic luster and no rust-like red luster. In poor quality steel pipe, the cross ribs are relatively small and may be full of unsatisfactory. Generally, the cross-section is mostly oval, and the inner diameter of the steel pipe will keep floating with great deviation. The longitudinal ribs of poor quality steel pipes will have wavy stripes and generally the packaging will not be neat and standard.
