Common surface defects of thick wall stainless steel pipes and their causes

What are the common appearance defects of stainless steel thick wall pipes? What are the causes of the differences? Here is a look at the introduction of the Haosteel.

1. Scratches

Wiping is the appearance of scratches on the outer surface of the stainless steel thick wall pipe. Because of its own strength is large, if there is a scratch is generally a longitudinal straight line of scratches, more commonly for the groove.

Formation reason: The common reason is that there are internal lines on the pipe material, and the residue is not eliminated in time when drawing, which will have a certain impact on the quality of stainless steel thick wall pipes.

Two, folding

Folding is the folding of the inside or outside of the stainless steel thick-walled pipe. There are spiral folds and continuous discontinuous folds.

Formation reasons: Most of them are caused by the poor material of the stainless steel thick wall pipe itself, and may also be caused by impurities, serious scratches and cracks on the surface of the material.

3. Cracks

The crack is a spiral distribution of small cracks on the surface of the stainless steel thick wall pipe, about one millimeter deep.

Formation reason: Usually good material stainless steel thick wall pipe is not cracks appear, generally due to the hot rolled pipe under the skin bubble or impurities caused, which is a defect generated in the processing process.

The above is the common appearance defects and reason analysis of stainless steel thick wall pipes! Common surface defects of thick wall stainless steel pipes and their causes
