ASTM A312 347H Welded Pipe & UNS S34709 Seamless Pipe supplier in India


Stainless Steel 347 Pipe

The 347 grade belongs to an austenitic stainless steel grade. The Stainless Steel 347 Pipe is designed with an outstanding chemical composition consisting of chromium and nickel. Columbium and tantalum are embedded in these pipes to help stabilize them in the system. These pipes showcase good resistance against corrosive and oxidative fluids and gases across a wide range of stress-induced environments. The AISI 347 Tubing shows excellent resistance in chloride or sulfuric acid systems. These tubes can be readily welded in place following standard welding procedures.

The ASTM A312 TP 347H Seamless Pipe is designed consisting of a higher carbon content. These pipes possess superior strength and are produced without any seams or welds. The extrusion process utilized in manufacturing these pipes gives them enhanced load-bearing capacity across different stress-induced systems. The material used to produce the UNS S34709 Seamless Tube makes them a little expensive. These tubes can only be produced in sizes up to 24 inches. The tubes in this seamless configuration are easy to work with and can be shaped in square, rectangular, round, and a range of shapes. This gives them an edge over pipes produced in the seamless grade. The UNS S34709 Welded Pipe is manufactured by rolling the metal followed by welding the pipe in place following an array of techniques. The pipes have lower strength and load-bearing capacity than seamless pipes but are cheaper than these pipes. ASTM A213 Tp347 Tubes are a seamless ferritic and austenitic alloy grades that are commonly seen in high-temperature boilers, super heaters, and heat exchanger equipment. These tubes have enhanced resistance to intergranular corrosion and have good tolerance to carbide precipitation in the temperature range between 800 to 1500 degrees F. For any questions and queries about the products in this grade or their pricing, get in touch with us for more information.
