Abstract: Elaborated in the article is the R & D of H FW oil casings in Baosteel, focusing on the present development situation, and the technological difficulties and process characteristics of the HFW casings as have been developed. Moreover, the R & D prospect of the HFW casings of Baosteel is discussed. It is pointed out that for further developing the HFW oil well pipes in Baosteel, the superiority of steel-making +pipe manufacturing +pipe processing, and consistent quality control should be taken, differential development be realized, product mix and output of the products as have been developed be expanded and increased, and large-sized heavy wall K55 casing and, high collapse-resistant casing and anti-corrosion casing be researched and developed.
