12Cr5Mol Seamless Steel Tubes For Petroleum Cracking

Introduction of 12Cr5Mol seamless steel tubes

12Cr5Mol seamless steel tube is a type of high temperature alloy steel pipe. It is specified in detailed according to GB/T 9948 standard. Steel grade 12Cr5Mol is equivalent to steel grade P5 and T5 of ASTM standard. In order to completely eliminate the internal stress, and improving the mechanical properties of the steel tube. 12Cr5Mol seamless steel tubes shall be heat treated before delivery. The delivery condition is complete annealing or isothermal annealing.

 

Features of 12Cr5Mol seamless steel tubes

1. Excellent oxidation resistance: 12Cr5Mol seamless steel tubes contain multiple alloy elements. The addition of chromium and molybdenum elements give it excellent oxidation resistance, expanding the service life of steel tubes.

2. High-temperature resistance: 12Cr5Mol seamless steel tubes have high heat stability, which still maintain good mechanical properties in high-temperature environments.

3. Good processing performance: 12Cr5Mol seamless steel tubes have good welding and processing performance, making it easy to perform cutting, bending, drilling and other processing.

Applications

12Cr5Mol seamless steel tubes have a wide range of applications in the petroleum industry. It is mainly used in key parts such as furnace tubes, heat exchanger tubes, and conveying pipelines in petroleum cracking units. During the high-temperature and high-pressure petroleum cracking process, 12Cr5MoI seamless steel pipes can stably transport petroleum and cracking products, ensuring the smooth progress of the petroleum cracking process. Meanwhile, its excellent corrosion resistance enables the steel pipe to operate stably for a long time in corrosive media, extending the service life of the equipment.
