These A269 TP347 stainless steel pipes are designed as per international and national standards and are available in customized length sizes and shapes for our esteemed clients. GNEE also offers the same at the best prices in the market.
A269 TP347 high temperature pipes are similar to TP321 pipes but have better resistance to weld intergranular corrosion and can provide stability and durability in a wide range of high temperature and corrosive conditions. In addition, A269 TP347 boiler tubes have good resistance to IGC after exposure to chromium carbide precipitation temperatures from 427°C to 816°C.
A269 TP347 polished pipes are widely used in high temperature, highly corrosive environments. In the chemical and petroleum industries, they have excellent corrosion resistance and are ideal for conveying corrosive liquids.
