Stainless Steel Elliptical Oval Pipes
Oval Pipes are stainless steel tubes with an elliptical cross-section, designed for both functional and decorative applications. 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 exceptional corrosion resistance. They are ideal for architectural design, marine applications, and automotive exhaust systems.
Manufactured through seamless or welded processes, such as TIG or laser welding, Oval Pipes are available in sizes with outer diameters from 9.5 mm to 108 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 oval pipes for use in furniture manufacturing 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 Oval Pipes suitable for harsh environments like marine and chemical processing. Their oval shape offers space efficiency and directional strength, ideal for tight-space installations and aesthetic designs.
Compared to round stainless steel pipes, 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.
Oval Pipes address challenges like corrosion, space constraints, and aesthetic requirements, delivering reliable, high-performance solutions for diverse industrial and decorative applications.
Stainless Steel Oval Pipes are specialized stainless steel tubes with an elliptical cross-section, designed for both functional and decorative applications. Compliant with standards like ASTM A554, A269, and A312, these pipes are typically made from austenitic grades such as 304 and 316, offering tensile strengths of 485–515 MPa and exceptional corrosion resistance. They are ideal for architectural design, marine applications, and automotive exhaust systems.
It is also more compact and the tube takes up less storage space, making it a good choice for smaller settings with limited workroom. Furthermore, the shape of steel oval pipe is more aerodynamic, which makes it the ideal option for products such as exhaust pipes on vehicles.
