In our country39。s total output of oil wells is more than 180W tons, the total of steel tube to %. Domestic market share than 80% of total exports 344W tons of oil wells, the import and export exceed import 322W tons, for two years to bee a exports. To the needs of, except with the help of steel chemical constituents and mechanical properties, metallurgy have strict requirements, manufactured to the outside diameter and bore diameter, a thick and threads argument, sealing and structural integrity and a strict demand. According to the design requirements, this paper is a design of petroleum tube based on the equipment conditions of the ?140mm mandrel mill in BaoSteel Co. Ltd. The product designed is of in . and in wall thickness. The design of the production process includes main parameter of machinery equipment。product’s balance of metal。product presentations。 product rolling schedule。 parameters adjusting。 tools design。identification passing。 mill cpacity。 the equipment strength and motor ability checking and econotechnical norms of the emphasis of these products is making rolling schedule。adjusting the calculation parameters。tools design。equipment strength and motor ability checking.
