精密管|品质好的精密管厂家

山东大鼎金属材料有限公司Precision seamless steel pipe (cold-drawn and cold-rolled) has high precision, no oxidation coating inside and outside the pipe, smooth and smooth surface, uniform wall thickness, high precision, small diameter of thin-walled tube to ensure that the error of the outside diameter of the tube in the inner and outer surface of the pipe presents varying degrees and quantities of corrugated ring marks, some are continuous, some are intermittent, may be the entire circle, there are. Not the whole circle. poor quality of pickling and lubrication, increase and change of friction during drawing, mechanical properties of steel pipe in length direction after heat treatment are not consistent, mandrel length and fineness are too large, and the position of mandrel before.
