雙金屬復合管復合工藝研究進展

Progress Made in Research on Cladding Process for Bimetal Clad Pipe

摘要: 綜合介紹了雙金屬復合管的復合工藝類型——機械復合和冶金復合；重點對這兩大復合類型的各種工藝優(yōu)缺點進行了對比分析，并提出應立足于國內現(xiàn)有生產水平，借鑒外國的研究和應用經驗，進一步開展對雙金屬復合管復合工藝和焊接工藝研究，為雙金屬復合管在惡劣環(huán)境油氣田的成功應用奠定基礎。

Abstract: Comprehensively elaborated here in the paper are the cladding process types for bimetal clad pipes, i.e., the mechanical cladding process and the metallurgical cladding process. Focused on are the comparative analyses of separate technological advantages and disadvantages of these two major cladding processes. Based on the analysis result, it is proposed that based on the current production level, domestic bimetal clad pipe-making circles should borrow relevant research achievements and application experiences as made abroad to continue R & D of cladding process and welding process for bimetal clad pipes in a bid to lay a solid foundation for successful application of such pipes in harsh-conditioned oil and gas field.
