Stainless Steel 347 Seamless Pipes
Arrow Piping Solutions is a leading manufacturer and supplier of high-quality Stainless Steel 347 Seamless Pipes. These pipes are made with niobium-stabilized austenitic stainless steel, offering excellent resistance to corrosion, oxidation, and stress at elevated temperatures. The inclusion of niobium enhances their longevity and makes them ideal for high-heat, high-pressure environments.
Our SS ASTM A312 TP347 Seamless Pipes consist of 9–13% Nickel, 17–20% Chromium, and Niobium, ensuring great durability, resistance to oxidation, and ease of fabrication. These pipes deliver a yield strength of 205 MPa and 40% elongation, showcasing superior mechanical integrity. Available in Round, Square, and Rectangle forms, the seamless structure ensures smooth flow and reliable performance in critical industrial applications.
Each pipe is labeled with grade, size, schedule, heat number, and manufacturer details. Our packaging includes waterproof wraps, plastic end caps, strong steel straps, and wooden crates to ensure secure delivery across the globe.
