The product is hot rolled steel strip of raw materials, often warm spiral shape, welded by automatic submerged arc welding process, API SPEC 5L, EN10217, GB/T9711.1, GB/T9711.2 standard product implementation. Mainly used for oil, natural gas industry to transport flammable fluid and non-flammable fluid and steel structure 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 the basic profile www.pvdfgc.com pvdf pipe www.bengguan168.com pump tube www.naimoguanjian.com pump Pipe www.thgangguan.com spiral steel pipe www.hbthgg.com Spiral Pipe |
