Common sense for ASTM A53 series steel pipe

We’ve discussed about ASTM A53 series steel pipe with one of our clients recently. We told him that no matter ERW or seamless steel pipe, ASTM A53 series have relative one for customers.

Here are four types of ASTM A53 series steel pipe in Threewaysteel:

ASTM A53 LSAW steel pipe:

Process: LSAW - UO(UOE), RB(RBE), JCO(JCOE, COE); DSAW - Double Submerged Arc Welded

Usage: Used for low pressure liquid delivery, such as water, gas, and oil.

SSAW ASTM A53:

Structural ASTM A53

Standard: Gr.A-D

Usage: gas, heating, water supply etc...

ERW steel pipe ASTM A53:

Test: Chemical Component Analysis, Mechanical Properties (Ultimate tensile strength, Yield strength, Elongation), Technical Properties (Flattening Test, Bending Test, Blow Test, Impact Test), Exterior Size Inspection, Hydrostatic Test, X-ray Test.

Standard: ASTM A53,ASTM A178,ASTM A500,ASTM A501,ASTM A691,ASTM A1020,ASTM A252,ASTM A672,EN 10219

Seamless Steel Pipe - ASTM A53:

From the outline, we can figure out that ASTM A53 contains steel pipe’s type ranging from LSAW, SSAW, ERW and seamless. So we need to consider the rightful one before wholesale.
