ASTM A53 B ERW Steel Tubing
ASTM A53 B ERW Steel Tubing, as the Abter most popular product, is manufactured as per ASTM A53 B ERW standard which covers seamless and welded black and hot-dipped galvanized steel pipe in NPS 1⁄8 to NPS 26 [DN6 to DN 650].
Under this standard, there are many test needed to be done to ensure the quality of ASTM A53 B ERW Steel Tubing.
ASTM A53 B ERW Product Analysis
The purchaser is permitted to perform an analysis of two ASTM A53 B ERW Steel Tubing from each lot of 500 lengths, or fraction thereof. Samples for chemical analysis, except for spectrographic analysis, shall be taken in accordance with Practice E 1806. The ASTM A53 B ERW Steel Tubing chemical composition thus determined shall conform to the requirements given in Table 1 as above.
Mechanical Properties
Tension Test
Bend Test
If ordered for close coiling, the ASTM A53 B ERW Steel Tubing shall stand being bent cold through 180° around a cylindrical mandrel, the diameter of which is eight times the specified outside diameter of the ASTM A53 B ERW Steel Tubing, without failure.
Flattening Test
The flattening test shall be made on welded pipe over NPS 2 [DN 50] in extra-strong weight or lighter.
Seamless Pipe:
Although testing is not required, ASTM A53 B ERW Steel Tubing shall be capable of meeting the flattening test requirements of Supplementary Requirement S1, if tested.
Electric-Resistance-Welded Pipe:
A test specimen at least 4 in. [100 mm] in length shall be flattened cold between parallel plates in three steps, with the weld located either 0° or 90° from the line of direction of force as required by 7.3.3.2 or 7.3.3.3, whichever is applicable.
Hydrostatic Test
The hydrostatic test shall be applied, without leakage through the weld seam or the ASTM A53 B ERW Steel Tubing body.
Plain-end ASTM A53 B ERW Steel Tubing shall be hydrostatically tested to the applicable pressure given in Table X2.2, and threaded-andcoupled ASTM A53 B ERW Steel Tubing shall be hydrostatically tested to the applicable pressure.
Nondestructive Electric Test
The weld seam of each length of electric-resistancewelded ASTM A53 B ERW Steel Tubing NPS 2 [DN 50] or larger shall be tested with a nondestructive electric test in accordance with Practices E 213, E 273.
