Production Process
Product Description
The Din 1629 St52.0 Seamless Steel Pipe is a high-strength, precision-engineered piping solution compliant with Germany’s DIN 1629 standard—specifically designed for mechanical engineering, structural applications, and fluid transport systems. As a seamless pipe, it is manufactured without welded joints, eliminating weak points and delivering exceptional uniformity in wall thickness, dimensional accuracy, and mechanical performance. The St52.0 grade (a low-alloy structural steel) further enhances its appeal, offering an optimal balance of tensile strength, ductility, and weldability—making it a go-to choice for demanding industrial and construction projects worldwide.
High strength & high pressure resistance: Welded-free design, more uniform overall performance, resistant to high pressure and less prone to leakage.
High dimensional accuracy: Especially for cold-drawn tubes, the dimensional control is precise, making them suitable for precision mechanical equipment.
High-temperature resistance and corrosion resistance: Suitable for high-temperature and corrosive environments such as boilers, heat exchangers, petrochemicals, etc.
Long service life: The combination of high-quality raw materials and precise craftsmanship ensures safer and more reliable operation over the long term.
Strong processability: Easy to be processed by deep techniques such as cutting, drilling and welding.
