Well-designed Roof Paving Slabs - 27SiMN Quenched And Tempered Steel Pipe API Series Pipeline Steel Pipe Carbon Steel Round Pipe – Ruixiang

Product Description

Carbon steel pipe or carbon steel pipe is made of steel ingot or solid pipe blank through perforation, and then made by hot rolling, cold rolling or cold drawing. Carbon steel pipe plays an important role in China’s steel pipe industry. The raw material of carbon steel pipe is round tube blank. The round tube blank is cut and processed by cutting machine, and the blank with a growth of about 1m is sent to the furnace for heating through conveyor belt. The billet is sent to the furnace for heating at a temperature of about 1200 degrees Celsius. The fuel is hydrogen or acetylene. The temperature control in the furnace is the key problem. After the round tube billet is discharged from the furnace, it should be pierced through the pressure piercer. Generally, the more common piercer is the conical roll piercer. This piercer has high production efficiency, good product quality, large perforation expansion and can wear a variety of steel grades. After perforation, the round tube blank is successively rolled by three roll cross rolling, continuous rolling or extrusion. After extrusion, take off the pipe for sizing. The sizing machine rotates into the steel embryo at high speed through the conical drill to form a steel pipe. The inner diameter of the steel pipe is determined by the outer diameter length of the sizing machine bit. After sizing, the steel pipe enters the cooling tower and is cooled by water spray. After cooling, the steel pipe will be straightened. After straightening, the steel pipe is sent to the metal flaw detector (or hydrostatic test) by the conveyor belt for internal flaw detection. If there are cracks, bubbles and other problems inside the steel pipe, they will be detected. Steel pipes should be strictly selected by hand after quality inspection. After the steel pipe is inspected, the number, specification, production batch number, etc. shall be sprayed with paint. And hoisted into the warehouse by crane.

27SiMn Steel Pipe = 27 silicon manganese steel pipe, which is one of the materials of seamless steel pipe, and the carbon content is between 0.24-0.32%. SIMN is listed separately because the content of silicon manganese in the five elements (carbon C, silicon Si, manganese Mn, phosphorus P, sulfur s) is about 1.10-1.40%.

Content: it has been operating in the field of seamless steel pipe in China for more than 20 years. The group has more than 10 seamless steel pipe production lines, mainly producing 27SiMn quenched and tempered steel pipe, API series pipeline steel pipe, carbon steel round pipe and American standard series steel pipe. It has a wide range of applications. Now its main customers are concentrated in South Africa, Central Asia, Europe and other countries, with thousands of tons of stock to supply customer demand.
