Vipul Pipes and Tubes, which is based in Chennai, India, is a well-reputed Carbon Steel DIN 17121 Pipes manufacturer and supplier, renowned for its high-performance structural steel piping solution. The pipes are manufactured according to the requirements of DIN 17121 standards, which define seamless circular tubes for general structural purposes. Our pipes are excellent in strength, weldability, and dimensional accuracy, making them suitable for both light and heavy engineering applications. Vipul Pipes and Tubes provides DIN 17121 pipes in different grades, sizes, and thicknesses to cater to the challenging requirements of construction, automotive, infrastructure, fabrication, and machinery manufacturing industries.
DIN 17121 Carbon Steel Pipes are mostly composed of low to medium carbon steel. Some popular grades are ST 37.2, ST 52.3, and others. Common chemical composition consists of Carbon (up to 0.22%), Manganese (up to 1.60%), with Phosphorus and Sulfur in controlled amounts (≤ 0.045%). These pipes provide very good mechanical strength with tensile strength of 340–630 MPa, yield strength of 235–355 MPa, and elongation up to 25%, varying with the grade. The material contains good impact resistance and is very good for welding and forming, thus suitable for application in structures.
