How to Choose Carbon Steel Pipe Size?
Oct .20.2026
When selecting carbon steel pipe (CS Pipe) size, pipe diameter (NPS/DN), wall thickness (Schedule Number), and pressure rating are three interrelated core parameters. Their selection requires comprehensive calculation based on the system design pressure, flow rate, and medium characteristics.
DIN 1629 St37 St52 Seamless Steel Pipes
Oct .15.2026
DIN 1629 is a German industrial standard primarily used for the manufacture of seamless steel pipes for chemical equipment, piping, vessels, mechanical engineering components, and steel structures, requiring high strength. It includes three base material grades (St37.0, St44.0, and St52.0) and covers mechanical properties, chemical composition, and manufacturing requirements. In simple terms, it specifies high-quality seamless carbon and alloy steel tubes for pressure-bearing applications.
