    厂家说如冷拔无缝钢管质量好坏何区分

    无缝钢管的运用规模很广,尤其是冷拔无缝钢管。人们对冷拔无缝钢管的质量是有需求的,那么区分冷拔无缝钢管质量是怎样的呢?首要质量好的冷拔无缝钢管在成分上是均匀的,在切头上看起来是很规整,摸着也是一种滑润的感受,而不是有毛刺刺手的感受。所以如果是残次资料的话,在切头上即是高低不平的,并且全部钢管看起来毫无光泽。如果是伪劣冷拔无缝钢管,那么在色彩上就会有格外的显着,是呈现出一种淡红色的色彩,还有残次冷拔无缝钢管在温度上也是达不到规范的。

    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 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. 还有即是伪劣的冷拔无缝钢管的横截面不是呈圆形,可能是呈椭圆形可能是别的形状,这即是因为厂家节省资料,偷工减料的成果,所以这就很不契合外形尺寸的规范。还有即是结疤表象的呈现,这点在优质的冷拔冷拔无缝钢管上是不允许呈现的,但是在残次冷拔无缝钢管上就很容易看到这一表象。

    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 is easy to see this appearance on the residual cold-drawn seamless steel tubes.
