API 5L production process
Process technology:With the development of octg pipeline steel and its welded pipe forming and welding technology advances, welded pipe for line pipe gradually expanded the scope of application, especially in large-diameter welded pipe within the groups, the advantages of more out wet, plus the cost of factors, occupies a leading position in the field of pipe line pipe, limits the development of stainless steel seamless pipe. In 2004 production of about 400,000 t of seamless line pipe, steel grades include X42-70, variety of onshore pipeline and subsea pipeline. API5L pipeline tube of production currently is used micro-alloy of heating processing process, stainless steel seamless tube of production cost obviously above pipe, and with steel level of improve, as X80 above steel level pipeline tube on carbon equivalent of limit, seamless steel tube of general process hard meet user requirements; currently the 12Cr1moV alloy tube production factory are in for improve its pipeline tube of anti-corrosion performance, low temperature, and high temperature environment in the of using performance stable and carried out research work. In this regard, our company has begun transformation process.
