As an important raw material for industrial manufacturing, the production process of seamless steel pipe directly affects the mechanical properties of the product. In this field, Changzhou Tianzhan Steel Tube Co., Ltd. has become the industry leader by virtue of its advanced production technology and strict quality control system. This paper will take the production process of hot-rolled and cold-drawn seamless steel pipe as an entry point to explore the differences in its impact on the mechanical properties of steel pipe, and analyze the production practice of Changzhou Tenjan Steel Tube Co., Ltd.

Hot rolled seamless steel pipe is heated by high temperature billet, and then through the rolling mill for rolling molding process. The hot rolling process makes the steel pipe have good ductility at high temperature, and can solve the quality problems caused by internal defects of the billet in the process. Moreover, the high temperature in the hot rolling process also makes the material grain to grow up fully, and the mechanical properties of the final product tend to be more stable. Ltd. Hot rolled seamless steel pipe is widely used in petrochemical, energy construction and other demanding industries because of its superior fracture resistance and high fatigue resistance.

In contrast, cold-drawn seamless steel pipe is produced at room temperature through a multi-pass cold-drawing molding process. The cold drawing process avoids the effect of high temperature on the material crystals, resulting in higher dimensional accuracy and better surface quality of the steel pipe. Meanwhile, due to the work-hardening effect, the hardness and strength of the cold-drawn steel pipe is significantly improved compared with that of the hot-rolled steel pipe. Changzhou Tenjan Steel Tube Co., Ltd. through the introduction of advanced cold-drawing equipment and technology, the cold-drawn seamless steel tubes are widely used in automobile manufacturing, precision instruments and other fields that require high precision and high strength.

To summarize, hot-rolled and cold-drawn seamless steel tubes have their own advantages and disadvantages in mechanical properties due to their different production processes. Choosing the right production process and product type can not only improve manufacturing efficiency, but also meet the specific needs of different applications. Changzhou Tenjan Steel Tube Co., Ltd. with its high quality production capacity and rich experience in the industry, meets the market demand and at the same time makes important contributions to promote the technological progress of the steel tube manufacturing industry.
