Our pipes are known for their superior strength, smooth surface finish, and long-lasting performance.
What are ST52 Welded Pipes?
ST52 welded pipes are made from ST52 grade carbon steel, a low-alloy, high-strength material that combines excellent toughness with superior weldability. These pipes are manufactured as per the DIN 2391 standard, which ensures precise dimensions and top-tier mechanical properties.
Due to their ability to withstand high pressure and temperature, they are used in various industries, such as construction, automotive, mechanical engineering, oil and gas, and more.
Key Features of DIN 2391 ST52 Welded Pipes
- High tensile strength
- Excellent impact resistance
- Easy to weld and form
- Uniform wall thickness
- Corrosion and wear resistance
- Seamless surface finish
- Cost-effective solution for heavy-duty applications
DIN 2391 ST 52 ERW Pipe – What Makes It Special?
The DIN 2391 ST 52 ERW pipe is made using the Electric Resistance Welding (ERW) process. This method involves welding the pipe edges without filler metal, resulting in a clean and smooth finish.
Benefits of ST52 ERW Pipes:
- Clean internal surface
- Uniform wall thickness
- No weld bead or weak points
- Ideal for hydraulic systems
- Cost-effective for mass production
Whether you’re working on fluid transfer systems or heavy machinery, DIN 2391 ST 52 ERW pipe is a reliable choice.
