1.3 Dimension range of processing steel pipe:
(1)O.D.: Φ8-Φ25mm
(2)Wall thickness: 0.3-1.0mm (square pipe and special-shaped pipeδ≤1.0mm)
(3)Length: 4~8M
1.4 Product (steel pipe) process flow:
Raw material (steel coil) → uncoiling → shearing and butt-welding → material accumulating → non-power leveling →mill-forming → high-frequency welding → removing burrs outside of weld seam → cooling → sizing → roughly straightening → fixed length cutting → run-out table
1.5 Milling speed: 20-90M/min (the speed is depended different pipe diameter standard and material thickness.)
1.6 Solid state high-frequency electrics power: 60 KW
1.7 Advised user's necessary accessories (only for reference):
(1)Mechanical equipment site: 35M × 4.0M (length × width)
(2)Electrical equipment site: 5M ×3M (length ×width)
(3)Machine unit foundation base (See supplier's base drawing)
(4)Two sets of 3-ton overhead crane
(5)Power supply:
a. Equipment motor: 22KW+4KW+1.5KW= 27.5KW
b. Solid state high-frequency electric: 60 KW
(6)Saw blades (Disk) for tracking saw, specification as per instruction book and quantity as per customer need.
(7) Magnetic bar (Impeder core) for welding pipe, purchase as per pipe making size. Normally, one standard pipe will be matched one standard magnetic bar.
(8) One set of Φ2", 6M high-pressure pumps for high-frequency electric and pipe-welding machine cooling. This device will be matched by buyer.
(9) One set of high-frequency electric part cooling water pool and pipe-welding machine, one unit volume 20 M3 with water pipe, water pressure meter and valve. (Decide size and quantity when installation on site, purchase from located market by buyer.)
(10) Machine unit electric circuit. Before assembling, circuit must reach the electric cabinet of high-frequency room. The electric connection joint of high-frequency room is to overall control table and button station. (Decide size and quantity when installation on site, purchase from located market by buyer.)
(11) High-frequency room for machine unit. It is adopting ground or attic according to customer's layout.
(12) One set of air compressor. (Purchase from located market by buyer.)
(13) Lifting equipment and tooling for installing machine, maximum weight of one part is 3 tons.
