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

What are the common appearance defects of stainless steel thi₹ck wall pipes? What are the causes of the differences? Here is a look at the introductλion 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 in☆ternal lines on the pipe material, and the residue is not eliminated in time whenπ drawing, which will have a certain impact on the quality of stainless steel th♠ick 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 m'ay also be caused by impurities, serious scratches and crack$s 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 millime≈ter 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, w€hich 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 pi÷pes and their causes
What are the common appearance defects of stainless ∑steel thick wall pipes? What are the causes of the differences? Here i•s a look at the introduction of the Haoshi.

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 εmaterial, and the residue is not eliminated in time when dr✔awing, which will have a certain impact on the quality of stai↕nless steel thick wall pipes.

2, folding

Folding is the folding of the inside or outside of t±he stainless steel thick-walled pipe. There are spiral folds and continuous discontin♠uous 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 materialγ.

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 defe↓ct generated in the processing process.
