This equipment is specially used for producingΦ19-Φ76mm,δ0.7-3.0 mm high-frequency straight seam welded pipe and corresponding square pipe and special-shaped pipe. The composition of equipment is from decoiler to fixed length cutting saw. Rolling speed can be adjusted correspondingly within suitable range of pipe diameter and wall thickness.
1.2 Applicable material
(1) Hot, cold-rolled steel strip and galvanized (As per GB700-88 or GB1591-88)
(2)Material: Low-carbon steel, low alloy steelδs≤345Mpa,δb≤610Mpa
1.3 ERW Tube Mill Other Model
