 Analysis of the causes of common defects in seamless steel pipes: (1) Reasons for the irregular distribution of folding defects. Improper viscosity of mold slag, obvious abnormality of molten steel vortex or abnormal vibration frequency of mold will cause slag entrainment. Most of the mold slag exists in the subcutaneous or surface area of the continuous casting billet, so there may be cracks or folding defects in the local area of a rolled tube. (2) Causes of the longitudinal distribution of large folding defects. The casting temperature of the open casting furnace is high, and the liquid level of the mold fluctuates greatly, which will cause longitudinal cracks on the surface of the continuous casting billet. Due to the longitudinal defects of cracks on the surface of the billet, heating the billet in an annular heating furnace (1280°C) for two hours, the cracked part is severely oxidized and decarburized during high temperature heating, and the rolling process cannot be rolled,...

 In the Oct last year of 2018, the new middle area contractor placed an order with 12 containers seamless steel pipe, after received our first order goods, customer is really happy for our quality.

 1. The thickness of capillary wall shall be uniform and there shall be few internal and external surface defects; External surface polishing and internal hole defect cleaning equipment shall be equipped. 2. Compared with the ordinary cold drawn steel pipe, the cold drawn precision seamless pipe production increases the pickling and re inspection process of hot-rolled capillary, which is mainly to ensure that the outer surface of the capillary is free of folding, cracks and other defects, and eliminate the capillary with folding, serious scribing, pitting and other defects on the inner surface. 3. Generally, the surface finish of the tools used in the production of cold drawn precision seamless steel pipe is required to be Ra0 Above 4, the dimensional accuracy shall reach above H3, and the hardness shall be above HRC70. At the same time, it is required that there shall be no steel sticking on the plug or die in the drawing process. 4. Annealing is a very important process in all co...
