The application of small-diameter seamless steel pipes has been applied in many areas, mainly in the metal industry, building materials industry and some construction pipeline industries. However, the production of small-diameter seamless steel pipes should follow certain technologies. The process flow of processing technology is very important, so conventional technology is indispensable. Next, we will mainly look at the production process flow of small-diameter seamless steel pipes.
The production process of small diameter seamless steel pipe mainly includes cold drawing, hot rolling and hot expansion. The main processing procedures include billet sawing, ring furnace heating, piercing, pipe rolling, sizing, cooling bed, straightening, pipe cutting and soot blowing, magnetic flux leakage testing, surface inspection and length measurement, weighing to packaging and warehousing.
The main technical standards include seamless steel pipes for structures (GB / t8162-2008), seamless steel pipes for fluid transmission (GB / t8163-2008), seamless steel pipes for low and medium pressure boilers (gb3087-2008), hot rolled seamless steel pipes for hydraulic support (GB / t1396-1998), seamless steel pipes for high pressure boilers (GB5310-2008), API casing and oil pipes (api5ct), pipeline steel pipes (api5l-44), and seamless steel pipes for low temperature pipelines (GB / t18984-2003).
