Look back at the history of failures with ERW and it explains itself. The liklihood of a failure is higher and the consequences are enormous.

MS pipe refers to mild steel pipe and ERW pipe is electric resistance welding pipe. The difference is ERW is made of very fine hard steel, while MS (black pipe) is made of malleable steel.

Electric resistant weld
ERW (Electric Resistance Welded) steel pipes offer several advantages, including cost-effectiveness due to efficient manufacturing processes, good strength and durability, and the ability to produce pipes in various sizes and thicknesses. However, disadvantages include susceptibility to weld defects, which can compromise integrity, and limitations in diameter and wall thickness compared to other types of pipes like seamless pipes. Additionally, ERW pipes may not be suitable for high-pressure applications or extreme temperatures.
The presence of ERW (electrolytically reduced water) can improve the efficiency of industrial cooling systems by reducing corrosion and scaling in the system, leading to better heat transfer and lower energy consumption.
SAW welding is a type of arc welding while ERW welding is spot or seam welding. SAW stand for submerged arc welding while ERW stands for electric resistance welding.
ERW (Electric Resistance Welding) pipe is manufactured by rolling metal and then welding it longitudinally across its length. Seamless pipe is manufactured by extruding the metal to the desired length; hence ERW pipe has a welded joint in its cross-section, while seamless pipe does not have any joint in its cross-section through-out its length.

MS pipe refers to mild steel pipe and ERW pipe is electric resistance welding pipe. The difference is ERW is made of very fine hard steel, while MS (black pipe) is made of malleable steel.
ERW pipes are round pipes welded from steel plates with longitudinal welds. It is used to transport oil, natural gas and other vapor-liquid objects, and can meet various requirements of high and low pressure.

SPP ERW pipe refers to Electric Resistance Welded (ERW) pipes manufactured by SPP, a company known for producing high-quality steel products. ERW pipes are created by rolling metal sheets and welding them along the seam using electric resistance, resulting in strong and durable pipes. They are commonly used in various applications, including construction, oil and gas, and water distribution due to their efficiency and cost-effectiveness.
One pipe is electric resistance welded (erw) the other is extruded through a thimble. In other words one has a seam the other doesn't.
