EN 10216-3 P355 Seamless Tubes Supplier

EN 10216-3 P355 seamless tubes are carbon steel pipes designed for pressure purposes, especially in high-temperature environments. These tubes are perfect for structural applications, power generation and the oil and gas sector because of their high strength and longevity. P355 pipe is known for its resilience to deformation, and cracking under pressure. It also comes with a fine surface finish and good weldability, which makes fabrication easy.

EN 10216-3 P355 Seamless Tubes Supplier

Multi Metals India is a trusted supplier of P355 seamless tubes in various sizes and thicknesses. These pipes undergo strict quality checks, including dimensional, mechanical, and visual testing, to ensure reliability.
