廠傢說如冷拔無縫鋼管質量好壞何區分

無縫鋼管的運用規模很廣，尤其是冷拔無縫鋼管。人們對冷拔無縫鋼管的質量是有需求的，那麼區分冷拔無縫鋼管質量是怎樣的呢?首要質量好的冷拔無縫鋼管在成分上是均勻的，在切頭上看起來是很規整，摸著也是一種滑潤的感受，而不是有毛刺刺手的感受。所以如果是殘次資料的話，在切頭上即是高低不平的，並且全部鋼管看起來毫無光澤。如果是偽劣冷拔無縫鋼管，那麼在色彩上就會有格外的顯著，是呈現出一種淡紅色的色彩，還有殘次冷拔無縫鋼管在溫度上也是達不到規范的。
Seamless steel tubes are widely used, especially cold drawn seamless steel tubes. People have a demand for the quality of cold-drawn seamless steel pipes, so what is the difference between the quality of cold-drawn seamless steel pipes? First of all, the quality of cold-drawn seamless steel pipes is uniform in composition, looks very regular on the cutting head, and feeling is a kind of smooth feeling, not a feeling of burr hands. So if it is incomplete information, it is uneven on the cutting head, and the whole steel pipe looks glossy. If it is fake and inferior cold-drawn seamless 环氧地坪steel pipe, then there will be a particularly remarkable color, is showing a light red color, and the residual cold-drawn seamless steel pipe in the temperature is not up to the norms. 還有即是偽劣的冷拔無縫鋼管的橫截面不是呈圓形，可能是呈橢圓形可能是別的形狀，這即是因為廠傢節省資料，偷工減料的成果，所以這就很不契合外形尺寸的規范。還有即是結疤表象的呈現，這點在優質的冷拔冷拔無縫鋼管上是不允許呈現的，但是在殘次冷拔無縫鋼管上就很容易看到這一表象。
Moreover, the cross-section of the fake cold-drawn seamless steel pipe is not circular, it may be elliptical or other shapes, which is because the manufacturer saves information, Jerry work and material reduction results, so this is not in line with the specification of shape and size. There is also the appearance of scarring, which is not allowed on high-quality cold-drawn seamless steel tubes, but it 彩色沥清地坪is easy to see this appearance on the residual cold-drawn seamless steel tubes.
