(3) The thickness of steel strip: 0.8-3.0mm (As per GB708-88)
(4) The width of steel strip: 60-240mm
(5) I.D. of steel coil: Φ450-Φ550mm
(6) O.D. of steel coil: Φ800-Φ1200mm
(7) Maximum weight coil: 3000kgs
3. Dimension range of processing steel tube:
(1) O.D.: Φ19.05-Φ76.2mm
(2) Square pipe size: 18x18~60x60mm
(3) rectangle pipe size:15x20~40x80mm
(4) Wall thickness: 0.8-3.0mm(square pipe and special-shaped pipeδ≤2.5mm)
(5) Length: 4-8m
4. Milling speed: 30-80M/min(choose different speed as per different pipe diameter and thickness)
5. Product (steel tube) process flow:
Raw material (steel coil) → uncoiling → shearing and end welding → material accumulating → non-power leveling → mill-forming → high-frequency welding → removing burrs outside of weld seam → cooling → sizing → roughly straightening → fixed length cutting → finishing tube
6. Advised user’s necessary accessories (only for reference):
(1) Mechanical equipment site: 55m×4.5m (length × width)
(2) Electrical equipment site: 5m × 4m (length × width)
(3) Machine unit foundation base (See supplier’s base drawing)
(4) Two sets of 10-ton overhead crane
(5) Power supply:
a. Equipment motor: 3KW+ 200KW+18.5KW+22KW+22KW+22KW=287.5KW
b. Solid-state high-frequency welder: 250 KW
(6) Saw blades for tracking saw, specification as per instruction book and quantity as per customer need.
(7) Magnetic bar for welding pipe, purchase as per pipe making size.
(8) One set of Φ3", 32m high-pressure pumps for pipe-welding machine cooling.
(9) One set of cooling water pool for pipe-making machine, the volume 30 m3 with water pipe, water pressure meter and valve. (Decide size and quantity when installation on site, purchase from market)
(10) Machine unit electric circuit. Before assembling, circuit must reach the electric cabinet of high-frequency room. Electric connection for high-frequency room to overall control table and button station. (Decide size and quantity when installation on site, purchase from market)
