| Product introduction | |||||||||
| Seamless steel pipe for chemical industry: mainly used for conveying high-temperature and high-pressure fluid on chemical fertilizer equipment. The representative materials are 20, 16Mn, 12CrMo, 12Cr2Mo, etc. | |||||||||
| Properties of chemical pipes; | 1. Manufacturing annular parts with chemical pipes can improve the material utilization rate, simplify the manufacturing process and save materials and processing time, such as rolling bearing rings and jack sleeves, etc. At present, steel pipes have been widely used to manufacture them. 2. Chemical pipes are indispensable materials for all kinds of conventional weapons, and barrels, gun barrels, etc. must be made of petroleum cracking pipes. Chemical pipes can be divided into round pipes and special-shaped pipes according to different cross-sectional areas and shapes. Because the area of oil cracking pipe is the largest under the condition of equal circumference, more fluid can be transported by circular pipe. |
