Hot-rolled steel pipe, a metal making process, is part of the hot-rolling process. The production method is mainly divided into the following steps:


1. Preparation stage: First, conduct quality checks on raw materials to ensure that their quality meets standards. Then, according to the required hot-rolled steel pipe specifications, the raw materials are cut and trimmed to meet the requirements of the hot-rolling process.


2. Heating stage: Put the prepared raw materials into the heating furnace and heat to the required temperature. During the heating process, the temperature and time must be controlled to ensure that the material is fully softened and easy to hot-roll.


3. Hot rolling stage: The heated materials are hot rolled through the rolling mill. During the hot rolling process, the pressure, temperature, and speed of the rolling mill must be controlled to ensure the quality and specifications of the hot-rolled steel pipe.


4. Cooling stage: After the hot rolling is completed, the hot-rolled steel pipe is cooled. There are many cooling methods, which can be selected according to actual needs.


5. Post-processing stage: Perform quality inspection, straightening, cutting, and other post-processing work on hot-rolled steel pipes to meet the needs of end users.


Overall, the hot-rolled steel pipe manufacturing method involves multiple steps, each of which has a significant impact on the quality and specifications of the final product. Therefore, during the production process, the operating parameters and process requirements of each step must be strictly controlled to ensure that the quality and performance of the final product meet standards.
