ASTM A335 P91 grade pipes are standard carbon ferritic stainless steel. The ASTM A335 P91 Pipe possess superior strength and is designed with a good chemical composition of chromium and molybdenum with alloying elements of vanadium, columbium, titanium, etc. The versatile A335 Gr P91 Chrome Pipe works well in highly corrosive and reducing environments. These pipes are seen in elevated pressure and temperature conditions. The P91 pipes have good creep strength and can be normalized at temperatures up to 1050 degrees C, followed by cooling. The SA 335 Gr P91 Round Pipe is designed in schedules between SCH 40 to SCH 160 and XXS. These hollow pipes have lengths of sizes of ½ NB to 36 NB and can be availed with a plain, beveled, and threaded end. They are specialized in large diameter sizes and possess outer dimensions between 19.05mm to 114.3mm. The SA335 P91 Material possesses a minimum tensile strength of 585mpa with a minimum yield strength of 415mpa. The material has a hardness of 250 max HB and can be elongated by a minimum of 20% in the system.
The pipes of the P91 grade can be produced in seamless, welded, and erw specification. ASTM A335 gr P91 Seamless Pipe is a high-strength grade that allows it to work well in different pressure and temperature setups. The absence of welds in these pipes allows them to have a smooth flow of media in the system. These pipes possess a 20% better pressure holding capacity than an A335 gr P91 Welded Pipe. Welded pipes, however, are available at lower prices, making them a viable choice in refineries and the oil and gas industry. The P91 Alloy Steel Welded Pipes are very reliable and can be produced in continuous lengths without risk of failure across tough conditions. ASME SA335 Grade P91 ERW Pipe has a longitudinal seam with accurate dimensional accuracy.
