Description
ASTM A**5 P*1 is the part of ASTM A**5, 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. 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.
ASTM A**5 P*1 alloy steel pipe
The different mechanical test requirements for pipes, namely,
transverse or longitudinal tension test, flattening test, and
hardness or bend test are presented.Both ends of each crate will
indicate the order no., heat no., dimensions, weight and bundles or
as requested.

Material & Manufacture
Pipe may be either hot finished or cold drawn with the finishing
heat treatment noted below. Heat Treatment
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 Hardness Test:
-
P*1 shall not have a hardness not exceeding **0 HB/**5 HV
[*5HRC].
Notes for Bend Test:
-
For pipe whose diameter exceeds NPS *5 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 *0 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
**0 without cracking on the outside of the bent portion.
