Carbon steel seamless steel pipe is a kind of long steel. The steel pipe has a hollow section and is widely used as a pipeline for transporting fluids, such as pipelines for transporting oil, natural gas, gas, water and certain solid materials. Compared with solid steel such as round steel, steel pipe has the same bending and torsional strength, and is lighter in weight. It is an economical section steel and is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes, automobile transmission shafts, Bicycle racks and steel scaffolding used in building construction, etc.
Small-caliber control of precision machining machinery manufacturing, mechanical structure hydraulic pressure, etc., can greatly save machining time, improve material production quality, and have different product quality at the same time. Pipe surface cleaning, pipeline branch and other obstacles, the hot-core pipe is automatically pulled out on the whole line and rolled, rolled into production, inspected and cut into the required wool, and the hot rolling mill is continuously promoted and hot rolled on the hot rolling mill. And hot rolling is carried out on the hot rolling mill, and it is advanced on the first-line rolling mill and rolling mill. When a large number of rolling mills appear in the automatic conveyor, they can be adjusted by the diameter gauge of the whole machine thickness to meet the requirements. It is the continuous workload of the continuous production line. The female worker's line requires a smaller and better quality machine tube working method, usually cold rolling is used to pull out or rolling on the cold rolling type combined in two holes, and the small diameter pipe is rolled in the cold rolling type on the cold rolling machine. A curved elbow piece composed of a face groove and a stationary head, usually cold drawn on a double-twisted machine, extruded in a single cylinder of twisted cold extrusion or drawn together with a chain stick movement Out of strangulation, made in imitation molds, can produce works of Confucius.
