Product Description

HG 165 big diameter tube mill from carbon steel
The mill is intended for manufacturing of round pipe of Φ76 mm-Φ168 mm with thickness of 2.0 mm–5.0 mm from cold-rolled and hot-rolled coil strip by means of unclosed tubular blank with its subsequent welding into tube, edge heating by means of solid state high-frequency welder, longitudinal seam welding in rolls of tube welding machine, cooling, further sizing or shaping and on-stream cutting of endless tube in measured lengths.

III. Basic conditions:

a) Steel Pipe Specification

1. Round Pipe diameter: Φ76 –Φ168mm

2. Square pipe: 60X60mm –125X125mm

Rectangle Pipe: 80X40-100X50mm

Pipe Thickness: 2.0 – 5.0mm

3. Pipe Length: 6.0m – 12.0m

IV. Equipment makeup and main parameters of single unit:

1. Hydraulic Single-arbor uncoiler with peeler

Mandrel expansion by hydraulic, Mandrel position rotation shall be manual, Pneumatic brake.

2. Five-roll Flattener

There are pairs of nipping and sending roller. Flatten rolls are arranged for two top and three below. Nipping and sending is pressured by hydraulic cylinder, flatter roll motor is cogged by worm wheel and worm screw reduced speed, the worm screws in front and one in back can come true be in-phase by sleeve connecting, which can ensure top leveling roll and under leveling roll be parallel, thereby which reach in the intention of flatten.

3. Shearing & butt welding machine

3.1 Hydraulic shearing parameters machine: Cutting by hydraulic system

4. 3. Horizontal spiral accumulator

The accumulator is composed by the following elements: Low bracket, Low bracket, Revolver, 7 rollers Flattening unit, 2 rollers feeding, and coil feeding system

Feeding speed: Max.200m/min


5. Forming & sizing section
