ASTM A335 P1 P22 Alloy Steel Pipes
ASTM A335 Grade P1 (ASME SA333 GR. P1) specification pipe is usually a ferritic alloy steel pipe used for high temperature service. This specification belongs to the low alloy steel pipe category. These pipes are manufactured through a seamless production process. ASTM A335 P22 is a "chromium-molybdenum" alloy steel pipe. The addition of chromium makes A335 alloy steel pipe ideal for power plants, refineries, petrochemical plants and oilfield services that transport fluids and gases at high temperatures and pressures.

ASTM A335 P1 alloy pipe Detailed Elongation Requirements
Elongation requirements for ASTM A335 vary based on the orientation of the specimen (Longitudinal or Transverse) and the wall thickness of the pipe.
| Specimen Type | Longitudinal | Transverse |
| Standard Specimen (Thickness ≥ 5/16" [8mm]) | 30% | 20% |
| Thin-Wall Specimen (Thickness < 5/16" [8mm]) | Calculated Deduction* | Calculated Deduction* |
*Note: For thickness below 5/16" (8mm), for each 1/32" (0.8mm) decrease in wall thickness, the elongation decreases by approximately 1.5% from the 30% base. Detailed values must be calculated using the formula specified in the ASTM A335 standard.

ASTM A335 P1 P22 Seamlesss Pipe Description
ASTM A335 P1 P22 Alloy Tube is an iron-alloyed steel made for high-temperature environments with good corrosion resistance in good environments.P22 grades are available in a variety of forms, including round tubes, pipes, and square tubes.P1 P22 grades are a chromium-molybdenum alloy with good corrosion resistance to acidic conditions and environments. It also has high tensile strength at high temperatures.The addition of molybdenum to A335 alloy seamless steel tubes improves the strength and flexibility of the steel, as well as its wear resistance, improving its properties.
A335 T1 T22 steel pipe is suitable for high-temperature superheaters and reheaters as well as high-temperature header tanks and steam pipes, especially in subcritical and supercritical boilers, where the temperature range is usually below 625°C. It can also be used in nuclear heat exchangers and oil crackers. In addition, it can be used for heat exchangers in nuclear power plants and furnace tubes in oil cracking plants.
GNEE Group, as a leading alloy tube manufacturer and supplier in China, can provide you with A335 alloy boiler tube, A335 high temperature tube, A335 superheater tube, A335 condenser tube, A335 heat exchange tube and so on. If you have an enquiry for A335 alloy pipe, please feel free to contact us.
