Initially, high-quality carbon or alloy steel is selected as the raw material. The billets undergo rigorous testing for chemical composition and mechanical properties to ensure they meet the standards for seamless pipe production.
The billets are fed into a high-temperature furnace for heating to the appropriate processing temperature. This step softens the steel, making it more malleable for subsequent forming processes.
The heated billets are pierced to form a hollow long cylinder. This step is crucial in seamless pipe manufacturing, requiring precise control to ensure uniformity and quality of the pipe material.
The pierced billets are rolled on a mill to gradually reduce the wall thickness and achieve the desired outer diameter and wall thickness through a continuous rolling process.
Finished seamless pipes undergo a series of quality inspections, including non-destructive testing, dimensional accuracy measurement, and surface examination, to ensure each pipe meets stringent quality standards.
