Raw Material Selection | We start with high - grade steel coils or sheets. These materials are carefully sourced to ensure they meet strict quality standards, providing a solid foundation for the pipes. The steel used has optimal carbon and alloy content, contributing to the pipes' strength and durability. |
Forming | State - of - the - art machinery is used to precisely form the steel into pipe shapes. Whether it's a round, square, or rectangular pipe, the forming process is highly controlled to achieve accurate dimensions. For round pipes, the diameter tolerance can be as low as ±0.5mm, ensuring a perfect fit in various applications. |
Welding | Advanced welding technologies, such as submerged arc welding (SAW) and high - frequency induction welding (HFIW), are employed. Our skilled welders ensure that each joint is flawlessly executed. The welding process creates a strong, seamless bond, with the weld strength often exceeding the base metal strength. This results in pipes that can withstand high internal pressures and external mechanical forces. |
Finishing and Quality Control | After welding, the pipes undergo a series of finishing processes, including surface polishing to remove any imperfections. Rigorous quality control checks are carried out at every stage. Non - destructive testing methods, such as ultrasonic testing and radiographic testing, are used to detect any internal flaws, ensuring that only the highest - quality pipes reach the market. |
