DIN 1629 Seamless Pipe Manufacturer

DIN 1629 is a German standard for seamless circular steel pipes used in industrial applications requiring high strength and pressure resistance. These pipes are made from non-alloy and alloy steels, with grades like St37.0, St44.0, and St52.0, tailored for various mechanical and structural uses. They are manufactured through hot or cold forming processes, ensuring precise dimensions and excellent surface quality.

DIN 1629 pipes are widely used in construction, machinery, and general engineering for components like pipelines, cylinders, and structural supports. The standard ensures superior durability, weldability, and performance under high-pressure conditions.

DIN 1629 Seamless Steel Pipe Standards and Properties

Standard and Material Grades: DIN 1629 specifies seamless circular steel pipes for general structural and mechanical engineering purposes. It includes non-alloy steel grades such as St37.0, St44.0, and St52.0. These grades are suitable for applications requiring different strength levels and operating temperatures up to 300°C.

Chemical Composition and Mechanical Properties

The chemical composition varies by grade. For example, St37.0 has a maximum carbon content of 0.17%, phosphorus of 0.04%, and sulfur of 0.04%. St44.0 has 0.21% carbon, while St52.0 has 0.22% carbon. Mechanical properties include tensile strengths ranging from 350 to 650 MPa and yield strengths from 235 to 355 MPa, depending on the grade and wall thickness.

Advantages of DIN 1629 Seamless Steel Pipe

DIN 1629 seamless steel pipes are versatile and suitable for a wide range of structural and mechanical engineering applications due to their excellent mechanical properties. They offer good weldability and can be used in various welding operations such as gas fusion welding, arc welding, and flash butt welding. These pipes have no restrictions on working pressure values and a maximum working temperature of 300℃. Their high tensile strength and durability make them ideal for use in structural components.

Applications of DIN 1629 Seamless Steel Pipe

DIN 1629 seamless steel pipes are commonly used in the construction of chemical plants, vessels, pipelines, and general mechanical engineering. They are also used in industries such as automotive, chemical, and petrochemical. These pipes are suitable for applications requiring operating temperatures up to 300°C.
