Corrosion-resistant And Space-efficient Tubing Solutions
Flat oval pipes offer corrosion resistance and aesthetic appeal for architectural, automotive, and industrial applications.
Flat Oval Pipes are stainless steel tubes with a flattened elliptical cross-section, designed for applications requiring both functionality and aesthetic appeal. Compliant with standards like ASTM A554, A269, and A312, these pipes are typically made from austenitic stainless steel grades such as 304 and 316, offering tensile strengths of 485–515 MPa and excellent corrosion resistance. They are ideal for architectural railings, automotive trim, and furniture design.
Manufactured through seamless or welded processes, such as TIG or laser welding, Flat Oval Pipes are available in sizes with outer diameters from 10 mm to 100 mm and wall thicknesses from 0.5 to 2.0 mm. Surface finishes like polished, brushed, or mirror enhance their aesthetic appeal and corrosion-resistant flat oval pipes for use in marine structures and heat exchangers. Standard lengths range from 5.8 to 12 meters, with customization available for specific project needs.
Rigorous testing, including tensile, flattening, and corrosion tests, ensures compliance with international standards. The high chromium (16–20%) and molybdenum (2–3% in 316 grades) content provides superior resistance to pitting and crevice corrosion, making Flat Oval Pipes suitable for harsh environments like marine and chemical processing. Their flattened shape offers space efficiency and directional strength, ideal for aerospace components and tight-space installations.
Compared to round or standard oval pipes, Flat Oval Pipes provide enhanced aesthetic appeal and better fit in confined spaces, though they may have slightly lower pressure resistance. Their versatility, low maintenance, and biocompatibility make them a preferred choice for hygienic and decorative applications, balancing performance and cost-effectiveness.
Flat Oval Pipes address challenges like corrosion, space constraints, and aesthetic requirements, delivering reliable, high-performance solutions for diverse industrial and decorative applications.
Flat Oval pipes are mainly produced with a diameter of 1,0 - 3,0 mm.

Carbon Steel Flat Oval Tube
Carbon steel flat oval tubes are cold-rolled and welded tubes.
Their relatively small form factor makes them great substitutes for bulkier round tubing solutions. This likewise makes them highly versatile and easy to install, especially on intricate structures like railing and balustrades.
Carbon Steel Flat Oval Tubes combine compact design with durability, offering cost-effective solutions for complex structural and decorative needs.
