 Honor: Liaocheng Tongyuan Steel Pipe Co., Ltd. is China's steel pipe Harbor http://www.zgggxxg.cn/ named the 2010 Top 10 credit units tongyuan, lodge a complaint, the transaction is all praise! Welcome to purchase! 
 An inferior steel pipe prone to folding. Folding steel pipe formed on the surface of the broken line, and this defect often throughout the entire product vertical. Of folding because of the shoddy manufacturers pursuit of high efficiency, the reduction amount is too large, resulting in the ears, under a rolling to produce folded, folded products after bending will crack the big decline in the strength of steel. Two. The appearance of inferior steel pipe often pockmarked face phenomenon. Ma surface is due to the rolling groove serious wear and tear caused by the steel surface irregularities, uneven defects. Exceeded due to shoddy steel pipe manufacturers to the pursuit of profit, often rolling groove rolling. 3. Shoddy steel pipe surface is easy to produce scarring. There are two reasons: (1). And shoddy steel pipe material is uneven, more impurities. (2). Shoddy materials manufacturers guide simple equipment, easy to stick to steel, these impurities the bite roller easy to produce scarring. 4. The surface of the inferior material easy to crack, because it blank adobe, adobe stomatal adobe in the cooling process due to thermal stress, cracks, cracks after rolling there. 5 The inferior pipe is easily scratched because of shoddy steel pipe equipment is very easy to produce glitch, scratch the steel surface. Depth scratch reduce the strength of steel. 6. And shoddy steel pipe without metallic luster, pale red or similar color of the pig iron, two two reasons, it's blank is adobe. Shoddy material rolling temperature standards, the temperature of the steel is by visual inspection, so that can not be carried out by the provisions of the austenite region rolling, the performance of the steel is naturally not standard. 7. Fine transverse ribs of the inferior steel pipe is low, often sufficient dissatisfaction with the phenomenon, because the manufacturers to reach a large negative tolerance, finished a few of the reduction is too large, iron-type small, pass sufficient dissatisfaction. 8. Shoddy steel pipe cross section appear oval because the manufacturers in order to save materials, finished roll two of the reduction is too large, the strength of this steel is greatly decreased, but does not conform to the standard of rebar Dimensions.
