The range of ASTM A335 P92 steel pipe sizes that may be examined by each method shall be subjected to the limitations in the scope of the respective practices. 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.

A335 P92 steel pipe Notes for Hardness Test
P92 shall not have a hardness not exceeding 250 HB/265 HV [25HRC].
A335 P92 steel 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
