ASTM A335 P11 Seamless Pipes
Standard Specification for Seamless Carbon Steel Pipe for High-Temperature Service
This specification2 covers nominal wall and minimum wall seamless ferritic alloy-steel pipe intended for high temperature service. Pipe ordered to this specification shall be suitable for bending, flanging (vanstoning), and similar forming operations, and for fusion welding. Selection will depend upon design, service conditions, Mechanical Properties, and high-temperature characteristics.
ASTM A335 Pipe (ASME S/A335, Chorme-Moly) is a seamless ferritic Alloy-Steel Pipe for high temperature service. Pipe ordered to this specification shall be suitable for bending, flanging (vanstoning), and similar forming operations, and for fusion welding. Sometimes referred to as “P Grade”, Chrome Moly Pipe is popular in P-Grades P1, P5, P9, P11, P22, and P91. The most common use of grades P11, P22, and P91 is in the power industry and petro-chemical plants, Grades P5 and P9 are commonly used in refineries.
A335 is often called chrome moly pipe because of the chemical makeup of Molybdenum (Mo) and Chromium (Cr). Molybdenum increases the strength of steel as well as the elastic limit, resistance to wear, impact qualities, and hardenability. Moly increases the resistance to softening, restrains grain growth and makes chromium steel less susceptible to embrittlement. Moly is the most effective single additive that increases high temperature creep strength. It also enhances the corrosion resistance of steel, and inhibits pitting. Chromium (or chrome) is the essential constituent of stainless steel. Any steel with 12% or more Chrome is considered stainless. Chrome is virtually irreplaceable in resisting oxidation at elevated temperatures. Chrome raises the tensile, yield, and hardness at room temperatures. The composition chrome moly Alloy Steel pipe make it ideal for use in power plants, refineries, petro chemical plants, and oil field services where fluids and gases are transported at extremely high temperatures and pressures.

ASTM a335 P11 pipes other mechanical test
| Transverse or Longitudinal Tension Test and Flattening Test, Hardness Test, or Bend Test |
|
For material heat treated in a batch-type furnace, tests shall be made on 5% of the pipe from each treated lot. for small lots, at least one pipe shall be tested. |
|
For material heat treated by the continuous process, tests shall be made on a sufficient number of pipe to constitute 5% of the lot, but in no case less than 2 pipe. |
|
Notes for Hardness Test: |
P91 shall not have a hardness not exceeding 250 HB/265 HV [25HRC]. |
|
Notes for Bend Test: |
For pipe whose diameter exceeds NPS 25 and whose diameter to wall thickness ratio is 7.0 or less shall be subjected to the bend test instead of the flattening test. |
|
|
Other pipe whose diameter equals or exceeds NPS 10 may be given the bend test in place of the flattening test subject to the approval of the purchaser. |
|
|
The bend test specimens shall be bent at room temperature through 180 without cracking on the outside of the bent portion. |
|
|
The inside diameter of the bend shall be 1 inch [25 mm]. |
| Hydrostatic test |
Each length of pipe shall be Hydro tested, at option of manufacture, nondestructive electric testing can be used. |
