Round Pipe Steel Bar Making Machine , High Frequency Straight Seam Tube
1.Applictions:
GGH-16z type precision high-frequency straight seam welding mill line is specialized to produce small pore diameter high frequency straight seam welded pipe for refrigeration & heat exchanger industry and structural pipe and industrial pipe with Φ6.35-Φ20mm and wall thickness of δ0.4-1.2mm(the pipes with Φ12mm-Φ16mm and thickness δ1.2-1.9mm should be processed on GGH-45z) Through optimization design, best materials choice, and accurately fabrication and rolls, the whole line can be reached high precision and high speed. Within suitable range of pipe diameter and wall thickness, pipe production speed can be adjusted.
