What is ERW Pipe? The Complete Guide from a Factory Perspective
By understanding the manufacturing process, standards, and applications of ERW steel pipes, you can save your project from high costs without compromising on quality.
An A53 ERW pipe is a carbon steel pipe that conforms to ASTM A53 specifications, manufactured using the electric resistance welding (ERW) process. while the “A53” standard is further divided into Grade A and Grade B, with Grade B having higher strength properties.
The A53 ERW steel pipe is suitable for low to medium-pressure applications like structural work, water, and steam transport.
A53 Grade A: Minimum tensile strength of 48,000 psi and minimum yield strength of 30,000psi.
A53 Grade B: Minimum tensile strength of 60,000 psi and minimum yield strength of 35,000 psi.
Sizes: 1/8” NPS to 26” OD
Schedules: S/10, S/20, S/40, STD, S/60, S/80, XH, S/100, S/120, S/140, S/160 and XXH
Scope
ASTM A53 and ASME SA53 are intended for mechanical and pressure applications and are 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.
A53 covers Seamless and Welded, Black and Hot-Dipped Galvanized nominal (average) wall steel pipe for coiling, bending, flanging and other special purposes and is suitable for welding.

The difference between ASTM A333 steel pipe and ASTM A106 steel pipe is that ASTM A333 is a low-temperature carbon steel pipe that can be used as a structural pipe, while ASTM A106 is a non-structural carbon pipe that is used in high-temperature applications.
Carbon steel pipe/ tube, also called CS pipe, are widely used in heavy industries like infrastructure, shipping, stills, mineral, oil, gas, and fertilizer industry pipeline systems.
Hot rolled seamless pipe is processed at high temperatures, resulting in a rougher surface and looser tolerances but lower cost. Cold drawn seamless pipe undergoes further processing at room temperature, delivering tighter tolerances, higher strength, and a smooth finish, though at a higher price point.
