Gas Water Delivery Seamless Carbon Steel Pipe , Carbon Steel Welded
Pipe Long Lifespan
ASTM A53 (ASME SA53) carbon steel pipe is a specification that
covers seamless and welded black and hot-dipped galvanized steel
pipe in NPS 1/8" to NPS 26. A 53 is intended for pressure and
mechanical applications and is also acceptable for ordinary uses in
steam, water, gas, and air lines.

6. 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.
