1.1 Summary:
This equipment is specially used for producingΦ 13-Φ 50.8mm(1/2'' 2''), δ 0.6-2.0mm high-frequency straight seam welded pipe and corresponding square pipe and special-shaped pipe(δ ≤ 1.5mm). The composition of equipment is from uncoiler 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 or cold-rolled steel strip (As per GB700-88 or GB1591-88)
(2)Material: Low-carbon steel, low alloy steelδ S≤ 345Mpa, δ B≤ 610Mpa
(3)The thickness of steel strip: 0.6-2.0mm (As per GB708-88)
(4)The width of steel strip: 40-160mm
(5)I. D. Of steel coil: Φ 450-Φ 550mm
(6)O. D. Of steel coil: Φ 800-Φ 1200mm
(7)Maximum weight coil: 1000kgs
1.3 Dimension range of processing steel pipe:
(1)O. D.: Φ 13-Φ 50.8mm(1/2'' 2'')
(2)Wall thickness: 0.6-2.0mm (square pipe and special-shaped pipeδ ≤ 1.5mm)
(3)Length: 4-8M
1.3 Milling speed: 20-90M/min
