　　The production process of API 5L A106/A53 seamless steel pipe is divided into the following steps: round tube blank → heating → perforation → three-roll cross rolling, continuous rolling or extrusion → tube removal → sizing (or diameter reduction) → cooling → straightening → hydraulic pressure Test (or flaw detection) → Mark → Warehouse. Seamless steel pipes are made from steel ingots or solid tube blanks that are perforated into capillary tubes, and then hot rolled, cold rolled or cold drawn.

　　API 5L A106/A53 Seamless steel pipes are mainly divided into: hot-rolled seamless steel pipes, cold-drawn seamless steel pipes, and cold-rolled seamless steel pipes.

　　The production process of cold-rolled seamless steel pipe is similar to that of cold-drawn seamless steel pipe. The difference is that the cold-drawing process is changed to a cold-rolling process. Generally, there are two-roller cold rolling and three-roller cold rolling, and some individuals have five-roller cold rolling. Cold rolling, there are many types of cold rolling machines.

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.
