Abstract:
Reviewed here in the article are the progresses as achieved by domestic steel-making enterprises in the aspects of development and innovation of the main products during the period of the 14th FYP. Focusing on the applications of the home-made pipes for deep well and extra deep well service and the 13Cr corrosion-resistant series tubing and casing to relevant fields, development and progress of the hydrogen linepipe and the CO
2 linepipe and the submarine linepipe, and the achievements associated with products like P92 and Super304 hi-pressure boiler pipes for the ultra supercritical power generation unit, and the metallurgical compound pipe and so on. It is regarded that although China has become a world steel pipe-making giant, many of the products as developed are based on the experiences of foreign product developments. Therefore we have to try to improve the product quality, create new steel pipe types, and speed up the product upgrade and development of original products as well.
