Maintain the quality of raw materials

The raw material primarily used in the production of seamless steel pipes is continuous casting billets. Ensuring the quality of the billets is crucial for the quality of the steel pipes, which primarily involves steelmaking levels, casting and cooling processes, as well as the molding quality.

Ensure the accuracy and uniformity of the furnace temperature control.

In seamless steel tube manufacturing, the thermal furnaces used include billet heating furnaces and steel tube heat treatment furnaces. The accuracy and uniformity of temperature control are two critical indicators for evaluating the quality of heating equipment and a crucial guarantee for the heating process. Therefore, manufacturers should strictly adhere to the service life and calibration cycle of thermocouples and inspect the uniformity of the furnace chamber temperature.

3. Streamlined inspection processes and equipment

Intermediate product inspection is a crucial step in controlling the quality of finished stainless steel seamless steel tubes, especially the inner wall surface quality, which requires strict control from the source.
