 1 shoddy steel prone to folding. Fold is formed on the surface of steel pipe line, this defect often throughout the product vertical. Have folded due to shoddy manufacturers for high efficiency, the amount of pressure is too large, resulting in the ears, under the fold to produce a rolling, folding of the product after bending will crack, the strength of steel fell. 2. Ma often shoddy steel exterior surface phenomenon. Pock is due to severe wear and tear caused by the steel rolling groove irregular uneven surface defects. Steel pipe manufacturers as inferior to the pursuit of profit, most often excessive rolling rolling groove. 3. Inferior steel surface is easy to produce scarring. There are two reasons: (1). Inferior steel material is uneven, impurities. (2). Shoddy materials manufacturers guide and guard equipment simple, easy to stick steel, these impurities after the roll bite is easy to produce scarring. 4. Inferior material surface easy to crack, because it is blank adobe, adobe pores more, adobe in the cooling process due to thermal stresses, cracks, after rolling through the cracks there. 5. Inferior steel is easy to scratch, because the poorly equipped and inferior steel pipe manufacturers, easy to produce glitch, scratch the steel surface. Deep scratches reduce the strength of steel. 6. Inferior steel no metallic luster, pale red or similar color of pig iron, for two reasons Second, it is adobe blank. 2, inferior wood rolling temperature non-standard, their steel temperature is visual, so the region can not be required for austenitic rolling, the natural properties of steel can not be reached. 7. Inferior steel cross bars thin and low, a phenomenon often fully satisfied, because the manufacturers to achieve large negative tolerance, a few of the finished product before the pressure is too large amount of iron-type small, hole fully satisfied. 8. Inferior steel oval-shaped cross section appear before, because the manufacturers in order to save materials and finished products before the two rollers of rolling reduction is too large, which greatly decreased the strength of steel, but steel does not conform to the standard dimensions.
