35CrMo seamless steel pipe is an important alloy steel pipe with excellent mechanical properties and high-temperature resistance, widely used in the petroleum, chemical, aviation, and aerospace industries.
1. Manufacturing Process of 35CrMo Seamless Steel Pipe:
The manufacturing process of 35CrMo seamless steel pipe mainly includes the following steps:
- Raw Material Preparation: High-quality 35CrMo alloy steel is selected as the raw material to ensure that the chemical composition and performance of the steel pipe meet the standard requirements.
- Hot Rolling: The preheated steel billet is fed into a rolling mill for hot rolling. Through multiple rolling and piercing processes, the billet gradually forms the initial shape of a seamless steel pipe.
- Heat Treatment: The hot-rolled steel pipe undergoes heat treatment processes such as annealing and normalizing to adjust the microstructure and improve the strength and toughness of the steel pipe.
- Cold Working: Cold drawing, cold extrusion, and other cold working processes further improve the dimensional accuracy and surface quality of the steel pipe.
- Subsequent processing: This includes pickling, rust removal, and painting to improve the surface finish and corrosion resistance of the steel pipe.
2. Application Areas of 35CrMo Seamless Steel Pipes:
Due to its excellent performance, 35CrMo seamless steel pipes are widely used in various fields:
- Petroleum Industry: Used in oil wells, oil pipes, and oil pipelines, subjected to high-pressure and high-temperature environments, requiring good corrosion resistance and tensile strength.
