The production of high-grade steel line pipe relies on a micro-alloying heating process.
The heat treatment process for high-grade steel line pipe is crucial.
The scope of welded pipe applications for pipelines has gradually expanded, particularly in the large-diameter group spacing range where welded pipe offers more advantages and is dominant due to cost factors. This has restricted the development of stainless steel seamless pipeline pipes. The development of pipeline steel plate technology and advancements in welded pipe molding and welding technology have contributed to this expansion. In 2004, approximately 400,000 tons of seamless pipeline pipe were produced, including steel grades X42-70, and varieties of onshore and submarine line pipe.
The production of high-grade steel line pipes involves a micro-alloying heating treatment process. Although the production costs of seamless stainless steel pipes are significantly higher than those of welded pipes, they are necessary for steel grades above X80 due to carbon equivalent restrictions. However, the conventional process of seamless steel pipes may not meet user requirements. Therefore, each 12Cr1moV alloy pipe manufacturer is working to improve the anti-corrosion properties of their line pipes and ensure stable performance in low and high-temperature environments through scientific research.
