ASME SA213 TP347 Seamless Boiler Pipe
GNEE sells over 1,500 tons of seamless and welded steel pipes annually to various engineering industries. Our goal is to ensure that our customers have the highest expectations for delivery and product quality of A213 TP347 Stainless Steel Seamless Pipe.
These SA213 TP347 High Temperature Stainless Steel Pipes are manufactured with cobalt and tantalum elements to stabilize the alloy, known by the trade name UNS 34700. They can effectively operate in the temperature range of 800°F to 1500°F. Additionally, the mechanical properties of SA213 TP347 Seamless Round Pipe, including creep and stress rupture properties, surpass those of Grade 304 or 304L. They are designed for applications in superheaters, steel boilers, and heat exchangers, ensuring superior performance and reliability.
SA213 TP347 Stainless Steel Boiler Pipe exhibits higher creep and stress rupture properties compared to 304, and offers high resistance to long-term heat and corrosion, making it ideal for engines, power plants, high-temperature pipelines, and other applications requiring high-temperature resistance.
