Seamless Tube

Tubing&casing

Baosteel OCTGs are widely used in Daqing Oilfield, Tarim Oilfield, Shengli Oilfield, Sichuan oil and gas fields with complicated geological conditions, and Bohai Bay Oil Field. Furthermore, its OCTGs are exported to many different countries in Europe, America, Middle East, Central Asia, and Southeast Asia. At present, Baosteel is capable of producing a whole series of OCTG products including tubings, casings and drill pipes. It can offer API standard products and non-standard products and has the capability to develop special threads and new grades with independent intellectual properties. The raw materials range from low-alloy steel through 13Cr martensitic stainless steel to top-end nickel-based alloy. Different categories of OCTG products have been gradually formed, including deep well series, anti-collapse series, anti-sulfur series, economical anti-CO2-corrosion series, and combinations of the above, to meet different needs for oil drilling and production under different complicated geological conditions.

Drill Pipe

aosteel is the only Chinese steel manufacturer with a complete drill pipe production process from steelmaking, rolling, upsetting, heat treatment, straightening, NDT, and friction welding till completion of drill pipes. Since it started production of drill pipes in 1989, Baosteel has, through 25 years of production experience, overcome a series of critical technical challenges hindering the production of drill pipes, such as steel purity, MIU length of internal taper, impact toughness and straightness. Starting from production of API drill pipes, it has now expanded to produce high-end non-standard drill pipes. Through its launches of new products such as ultrahigh-strength, ultrahigh-toughness, super-large-displacement, super 13Cr, sulfur-resistant, BGDS high anti-torsion, BGST super high anti-torsion, and NC52 non-standard drill pipes, it has been able to develop advanced drill pipe production processes that meet complicated requirements for drilling deep wells, ultra-deep wells, directional wells, and extended reach wells. For example, Baosteel products were successfully used in Tarim Oilfield to break the record of the world's deepest well by deveolping a 7,620-meter well and a 8,023-meter well in a row. Besides, Baosteel also created the world record of horizontal directional crossing of 2,350 meters, making its drill pipe products among the world's leaders. At present, apart from wide application in domestic oilfields, Baosteel drill pipes are also sold to other countries and regions such as the United States, Canada, Russia, the Middle East and Southeast Asia.¡£

Line Pipe

Baosteel seamless line pipes are widely used in petroleum and natural gas industries for transmission of media such as gas, water, oil, and slurry (liquid mixture), applicable in both terrestrial and marine environments to address complicated working conditions such as low temperature, acidity, and huge drop height. Besides, Baosteel can also develop economic grades (steel types) for users to meet their special requirements. For instance, Baosteel partnered with Northwest Bureau to develop the 1Cr seamless line pipe, which achieved a good balance between cost efficiency and corrosion resistance and was highly recognized by users. The subsea line pipes supplied by Baosteel for Nanhai Liwan Deepwater Pipeline Project (1,500 meters) also won users' recognition because of their excellent pipe-end dimensional accuracy and weldability which facilitated the onsite automatic welding process and enhanced the efficiency of pipelaying.
