ASTM A335 P92 High pressure boiler pipes
ASTM A335 P92 is the part of ASTM A335, The pipe shall be suitable for bending, flanging, and similar forming operations, and for fusion welding. The steel material shall conform to chemical composition, tensile property, and hardness requirements.
ASTM A335 P92 high pressure semaless boiler pipe, The range of ASTM A335 P92 seamless alloy steel pipe sizes that may be examined by each method shall be subjected to the limitations in the scope of the respective practice.
Each length of pipe shall be subjected to the hydrostatic test. Also,
each pipe shall be examined by a non-destructive examination method in
accordance to the required practices.
The range of ASTM A335 P92 pipe sizes that may be examined by each method shall be subjected to the limitations in the scope of the respective practice.

Material & Manufacture
Pipe may be either hot finished or cold drawn with the finishing heat treatment noted below.
A / N+T
N+T / Q+T
Mechanical Tests Specified
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 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.
