Characteristics of pipes for petroleum cracking, fertilizer, and chemical industry
Steel pipes for petroleum, petrochemical, and chemical industries (including coal chemical industry), commonly referred to as steel pipes for chemical industry, generally refer to steel pipes used in petrochemical industry, including petroleum refining, chemical fiber production, coal chemical industry, chemical industry, and fertilizer production. According to the production method of steel pipes, they are divided into seamless steel pipes and welded pipes. According to the type of steel, it can be divided into carbon steel pipes, alloy steel pipes, stainless steel pipes, as well as composite steel pipes widely used in recent years. Due to the fact that the main physical and chemical reactions in the three chemical production process are carried out under specific pressures and temperatures. The raw materials, reaction processes, and products all have temperature and pressure requirements, and the raw materials, reaction processes, and products all have a certain degree of corrosiveness. Therefore, there are certain technical requirements for steel pipes used in specific chemical production.
The characteristic of China’s energy resources is rich in oil and less coal. Utilizing China’s abundant coal resources and adopting coal liquefaction technology to convert coal into high-quality liquid fuel is an effective way for China to utilize thermal coal, especially high sulfur coal.
Direct coal liquefaction is a hydrogenation process under high pressure and high temperature, so process equipment and materials must have high pressure resistance and hydrogen corrosion resistance under critical hydrogen conditions. In addition, the materials directly liquefied contain solid particles such as coal and catalysts, so it is necessary to solve technical problems such as sedimentation, wear, and sealing caused by the processed particles. Using large-diameter seamless steel pipes for inclined conveying can suppress the phase separation of slurry and residue in the conveying pipe during the process. The wall thickness of seamless steel pipes can reach up to 105mm
Seamless steel pipes for petrochemical and chemical industries (including coal chemical) and their temperature range for use in petrochemical and chemical industries (including petroleum cracking, fertilizer, chemical pipes) are commonly referred to as steel pipes for petrochemical and chemical industries. They generally refer to steel pipes used in petrochemical industries, including petroleum refining, chemical fiber production, coal chemical, chemical industry, and fertilizer production. According to the production method of steel pipes, they are divided into seamless steel pipes and welded pipes. According to the type of steel, it can be divided into carbon steel pipes, alloy steel pipes, stainless steel pipes, as well as composite steel pipes widely used in recent years.
