During manufacturing, steel strips are formed into a round shape, and the edges are heated by electrical resistance before being pressed together to create a strong longitudinal weld seam.<\/p>\n\n

The meaning of ERW can be explained as follows:<\/p>\n\n

In simple terms:<\/p>\n\n

ERW pipe means a steel pipe made by rolling steel strip into a cylindrical shape and welding the seam using electrical resistance heating.<\/strong><\/p>\n\n

Unlike traditional welding methods, modern ERW pipes mainly use high-frequency welding technology<\/strong>, which provides accurate control of weld quality and production efficiency.<\/p>\n\n
