pipe alloy

ASTM A335 P91 Alloy Steel Pipe is a seamless pipe meant for high temperature applications. These Alloy Steel Pipe are made from ferritic Alloy-Steel. Chemically the a335 P91 welded steel pipe contains elements like Molybdenum (Mo) and Chromium added to the alloy. When Molybdenum and chromium are added to the alloy, there is an increase in the tensile strength of the sa335 grade P91 alloy pipe. The tensile strength of the a335 grade P91 pipe is 415 Mpa, while its yield strength is 205 Mpa. The elongation percentage of the alloy steel pipes ranges between 20% to 30%.Further Molybdenum improves the pipe’s resistance to wear, its impact qualities, hardenability, as well as its elastic limit.  While chromium is an important alloyant in the a335 P91 steel pipes, it is known to prevent corrosion and has high resistance to oxidation at elevated temperature. Corrosion is also prevented in these pipes as they are surface treated or coated. Hence industrial plants, factories and refineries used the astm a335 P91 pipe for transportation of fluids and gases like water, oil and steam at extremely high pressures and temperatures. For example, they are used in power plants, oil refineries and petrochemical plants.The sa335 P91 grade of pipes is most suitable for applications in the steam boiler. They can be used in boiler drums and parts, pressure vessels in apparatus engineering etc. Further, since the sa335 P91 material pipe can withstand high temperatures, they find application in permanent operations, where the wall temperatures escalate to about 1202 °F or 650 °C.
