Durable Seamless Carbon Steel Pipe ASTM A53 Grade A Pressure Vessel
Manufacturing
ASTM A53 pipe (also referred to as ASME SA53 pipe) is intended for
mechanical and pressure applications and is also acceptable for
ordinary uses in steam, water, gas and air lines. It is suitable
for welding and for forming operations involving coiling, bending,
and flanging, subject to certain qualifications.

7. Test Methods
The test specimens and the tests shall conform to those described
in the latest issue of Test Methods and Definitions A370.
Each longitudinal tension test specimen shall be taken from a pipe
end and shall not be flattened between the gage marks.
Test specimens for bend tests and flattening test shall be taken
from pipe. Test specimens for flattening tests shall be smooth on
the ends and free from burrs.
Tests shall be conducted at room temperature.
