The ASTM A335 P22 Pipe covers the seamless ferric alloy steel pipes which can deal with the high temperature services. The specification of this pipe covers the major chunk of both nominal and the minimum wall thickness pipes which are required. This is one of the most acknowledged seamless pipes that come under the carbon steel pipes category. It also has some added chromium, and molybdenum and with some vanadium too. The presence of chromium or chrome improves the high temperature strength and also increases the oxidation resistance while raising the tensile, hardness and yield of the pipes at room temperature.

The presence of molybdenum in the pipe enhances the strength; resistance to water and the elastic limit along with harden ability and impact qualities. This furthermore increases the resistance to softening and restrains the grain growth while it makes the chromium steel as one less susceptible to the process of embrittlement. It also contains molybdenum which is one most affective additive that assists in increasing the high temperature creep strength while also enhancing the corrosion resistance of the whole steel product and inhibits the pitting.

The ASTM A335 P22 Pipe and this specific grade are actually used under high temperature service applications and it is also a tolerant substance within its microstructure. If we get down to the applications of tehse ASTM A335 P22 Pipe, the list would never end. They are primary used in the Chemical equipment, Heat exchangers, Pharmaceutical equipment, Condensers, Pulp and paper industry, Off-shore oil drilling companies and at a lot more places.
