The difference between carbon steel erw and seamless black steel pipe
Carbon steel erw
Electric resistance welded (ERW) steel pipe is carbon steel erw formed by rolling steel and then welding it longitudinally along its length. Therefore, ERW steel pipe has a welded joint in its cross section.
Seamless black steel pipe
Seamless pipes are manufactured by extruding metal to the desired length. Therefore, they do not have any joints in the cross-section of their entire length.
Comparing carbon steel erw and Seamless Black Steel Pipe
There are several differences between carbon steel erw and seamless steel pipe.carbon steel erw are used to transport liquids such as fuels, gases, etc., regardless of their pressure, making them one of the most typical delivery pipes in the world. Seamless pipe, on the other hand, is a square or rectangular shaped steel pipe without seams around it, with a hollow cross-section, used for conveying liquids and making structural and mechanical parts, due to its high bending and torsional strength and impressive Incredibly light.
