Abstract: Up to now Baosteel has set up a complete process flow production system as from steel melting to thread processing of the 13Cr tubing and casing. Descried here in the article are the Baosteel-made progresses as related to the main aspects of the 13Cr tubing and casing production，including the steel-making，the rolling technology，the heat treatment technology，the NDT technology and the thread processing technology，etc. The consistent technology capacity as from the liquid steel to the thread has got tremendously enhanced，which significantly supports the smooth development of domestic hi-temperature，hi-pressure oil/gas wells，deep water oil/gas wells and gas storage wells.
