Following the decline in crude steel production in the first ten days of this month, crude steel production rose again in the first ten days of this month. Inventories of heat preservation and anticorrosion pipe manufacturers and factories also declined. The production situation of secondary or steel plants is not clear. At present, as raw material prices continue to fall, consumer enterprises still have profit margins; coupled with financial pressure, most steel mills need to maintain operation in order to continue to obtain savings; therefore, steel mills still adhere to a higher start-up rate; Anshan region, for example, as of this month, Tangshan blast furnace start-up rate is about.0%, high production capacity application rate. Up to.0%, the rate of increase was normal.山东大鼎钢管厂、山东大鼎金属材料有限公司

Compared with solid steel such as round steel, seamless steel tube has the same bending and torsion strength and light weight. It is an economical steel. It is widely used in the manufacture of structural mechanical parts such as oil drill pipe, automobile transmission shaft, bicycle frame, steel scaffolding for construction. The use of seamless steel pipe to manufacture ring parts can process, save materials and processing time, such as rolling bearing rings, Jack sleeves and so on. Steel pipes are also indispensable materials for various conventional weapons, such as pipes, guns and so on. According to the shape of the section area, the steel pipe can be divided into circular pipes and special-shaped pipes. Because the circumference is equal and the circular area is large, the circular tube can transport more fluid. In addition, the ring section under the action of internal and external radial pressure, the force is more uniform, so most of the steel pipes are circular.
