Dealing with Low-Frequency-Welded ERW-jfkthe problem of contact resistance is virtually nonexistent. As a result, high-frequency-welded pipe tends to be relatively free of the bondline defects that were common in the low-frequency and d.c.-welded material. The performance of ERW materials has improved steadily with time as shown in Table 1.
The High-Frequency Longitudinal Seam Welded Steel pipe is also called ERW steel pipe, it's manufactured by cold-forming a sheet of steel into a cylindrical shape. Current is then passed between the two edges of the steel to heat the steel to a point at which the edges are forced together to form a bond without the use of welding filler material.
