X120 UOE Linepipe With Improved Properties and Varied pipe production technology and properties of x120 linepipe polishing
Oct 02, 2008 · Nippon Steel has developed X120 UOE linepipe as a part of joint development program with ExxonMobil. After establishment of the basic production technology of X120, the mechanical properties have been improved, especially to increase the suitability to strain based design application and the size range has been expanded.When did Nippon Steel start developing X120 linepipe?Nippon Steel started joint development of X120 with ExxonMobil in 1996 when most linepipe produced was grade X65 or lower and very limited amount of X80 had been manufactured. Therefore, a large step in linepipe manufacturing technology was required to develop X120 from the existing technological basis.See all results for this questionWhat kind of steel is used in pipeline pipe?B, X42, X46 and X52, X56, X60, X70 and X80, now the big steel mills and factories have developed steel grade for X100 and X120 measures of pipeline steel. Steel pipe of higher steel grade, relatively have higher requirement of raw materials and production, the carbon equivalent between different grade of steel is strictly controlled.See all results for this question
What are the different grades of API 5L pipe?
API 5L steel line pipe adopts different steel grades, generally are Gr. B, X42, X46, X52, X56, X60, X65, X70, X80. Some manufacturers are capable of manufacturing steel grade up to X100 and X120. As the steel line pipe grades higher, more strictly control on the carbon equivalent control, and higher mechanical strength performances.See all results for this questionUDC 669 . 14 . 018 . 292 - 462 . 2 : 621 . 643 . 23 pipe production technology and properties of x120 linepipe polishingAn X120 linepipe requires far higher production technology than an X65 or X80 linepipe does, and the research and development ac-tivities for the X120 linepipe in all the technical fields such as mate-rial design, steelmaking, casting, plate production and pipe produc-tion (UOE press forming, seam welding, etc.) had to be organized in an organically integrated manner. 3. Product Development and Its PropertiesThe Thermomechanical Controlled Processing of High pipe production technology and properties of x120 linepipe polishingThe next frontier is the X100-X120 strength range, where bainitic or martensitic microstructures are required. It is clear that achieving a high-strength bainitic microstructure in heavy plate requires a high Carbon Equivalent value (C. E. II or Pcm), a rapid cooling rate, and a low water-end temperature.
Prospects and State of the Art of TMCP Steel Plates for pipe production technology and properties of x120 linepipe polishing
Higher strength and higher thickness are ongoing demands on plates for pipes and structural applications. At the same time other properties like toughness and weldability must be kept or even be improved. As a consequence these demands must be achieved with limited addition of alloying. Specific aspects must be incorporated in the design of thick plates.Pipe Production Technology and Properties of X120 To conrm X120 mass production technology, more than 100 pipes were manufactured in a small-scale, commercial-production runa mini-roll. The produced pipe generally met the dimensional tolerances and mechanical prop-erty targets, but improvements are planned. Field bending of the X120 pipe has been demonstrated, and the resistance toPipe Production Technology And Properties of X120 LinepipeTo provide a lower cost option for long distance gas transmission, X120 UOE linepipe has been developed. After development of heavy plate and basic seam welding technology, finite element models and forming tests in the UOE mill established the forming conditions and tooling design criteria to solve the problem of the large spring back that occurs during forming of the plate.
