摘要
Abstract
Described here in the article are the three main aspects of the domestic MF hot-expanded steel pipe production,i.e.,the present development situation of the manufacturing process,the technological progress,and the process of preparation(revision)of applicable product standards.It is pointed out that the revision of the definition concer-ning the steel pipe manufacture methods as specified in Standard GB/T 5310-2023 Seamless Steel Pipe for High Pressure Boiler symbolizes that the said steel pipe MF hot-expansion process has been approved in relevant National Standard.Also elaborated are some new understandings of the steel pipe MF hot-expansion process in associated with such aspects as the process flow,the quality control of the mother tube,the material determination and the shape design of the mandrel and the intelligent formation control system,etc.Furthermore more thinking about the said MF hot-expanded pipe is made,invo-lving R&D,market access and approval of the new product as well as low carbon and energy-saving production and so on.关键词
