?? Shandong shunxinda Machinery Co., Ltd. (13969559358) is located in Liaocheng Economic Development Zone, Jiangbei water city with beautiful scenery. It is a company specializing in the production, processing and sales of precision seamless pipe, cold drawn precision seamless pipe and cold-rolled precision seamless pipe
Foreign 20Cr precision steel pipe focuses on breaking the industry boundary
It is suggested that efforts should be concentrated on breaking the industry boundary, the prospect of building a 20Cr precision steel pipe mill in China, the development trend of oil and gas transmission pipe abroad, the production status and market demand forecast of domestic oil and gas transmission pipe. It is pointed out that it is necessary and urgent to build a set of high starting point uoe20cr precision steel pipe unit with world advanced level, so as to meet the demand of domestic pipeline construction and enhance the competitiveness of international market. Pipeline transportation is a convenient and economic transportation mode for oil, natural gas, coal and other energy media. The steel pipes used in pipeline transportation mainly include spiral 20Cr precision steel pipe, precision seamless steel pipe in stock and seamless pipe, etc. The spot production methods of precision seamless steel pipe can be divided into longitudinal high frequency welding and longitudinal submerged arc welding. LSAW is generally used to produce large diameter 20Cr precision steel pipe.
? With the development of 20Cr precision steel pipe industry, a simple calculation method for die matching of cold drawn steel pipe with short core head has been widely used for high strength and high toughness pipeline steel pipe_ D and wall thickness reduction coefficient K_ S instead of traditional elongation coefficient ¦Ë To make it become a single successive multiplication operation. In recent years, there have been many small seamless gap CI in China, or other related matters (such as checking pipe factories, which mainly produce the value of large elongation coefficient of finished pipe mainly by cold drawing, and sometimes it is necessary to check the material for new products. In order to improve the cold drawing technology of these factories and tap the potential of drawing force or drawing safety factor in each pass, the author recommends a short core head
