2. Main components

2.1 Uncoiler

Structure type: Double-side 360ºrotary manual expanding tight, which insure steel coil feeding alternatively and make steel strip going into accumulator freely.

Applicable range: 78-240mm steel strip width, 1.5 -3.0mm thickness,

Φ800-Φ1200mm steel coil O.D., Φ450-Φ550mm steel coil I.D., Max.2500kgs steel coil weight.

2.2 Shearing and end welding machine, which insure double steel coil shearing tidily and then welding together and leveling weld seam.

2.3 Forming, welding table and sizing unit

(1) Feeding & leveling device:

Form: Up and down five rolls are passively leveled for straightening strip steel before it is fed into forming unit.

(2) Forming device:

Mainly roughly mill-forming steel strip and controlling weld seam.

a. Horizontal roll frame:

Quantity: 7

Structure: 45#Cast steel, double housing, changing rolls in the side

Diameter of horizontal roll’s shaft: Φ70mm, material: 40Cr

b. Vertical roll frame:

Quantity: 9

Type: Passive rotation

Diameter of vertical roll’s shaft: Φ40mm, material: 45# steel forging

c. Adjusting method: Single spiral pole manual adjusting

d. One set of bed for installation

(3) Guiding extruding and welding scraping apparatus:

a. One set of guide roll stand for controlling direction of pipe seam to insure pipe seam flatly and straightly entering into extruding rollers.

b. Three sets of extruding roll stand for controlling weld seam to realize successful welding.

c. Two sets of scraper frame for scraping outside weld seam

(4) Sizing device: Mainly fine shaping pipe after welding and controlling size accuracy. Each 5 sets of horizontal roll stand, vertical roll stand, three sets of gearbox branch (double connection), and 10 sets of universal shaft. (Structure same as forming device)

(5) Roughly straightening machine frame:
