1. Description of product1.1 Summary:
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. This equipment is specially used for produce Φ8~Φ25mm, δ0.3~1.0mm high-frequency straight welded pipe and corresponding square pipe and special-shaped pipe (δ≤1.0mm).
1.2 Applicable material:
(1)Hot or cold-rolled steel strip (As per GB700-88)
(2)Material: Low-carbon steel, low alloy steel
(3)The thickness of steel strip: 0.3-1.0mm (As per GB708-88)
(4)The width of steel strip: 25-80mm
(5)I.D. of steel coil: Φ350-Φ450mm
(6)O.D. of steel coil: Φ800-Φ1000mm
(7)Maximum weight coil: 800kgs
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):

(2)Electrical equipment site: 5M ?/span>3M (length ?/span>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,>(8)>Φ2 ' , 6M high-pressure pumps for high-frequency electric and pipe-welding machine cooling. This device will be matched by buyer.
(9)>(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>(11) High-frequency room for machine unit. It is adopting ground or attic according to customer's layout.
