High Frequency Welding ERW Carbon Steel Pipe Mill
Product Specifications
ERW pipe mill is designed to produce API, EN, ASTM, GB/T standard
pipes for transporting water, gas, and oil, as well as construction
pipes. This high-frequency straight seam welded pipe mill processes
fixed strips after slitting, forms them into pipes through rollers,
and welds the edges using high-frequency current.
