HG 127 Straight Seam Precision Square Pipes Round Tubes for oil road building materials
HG127 high frequency straight seam precision welded pipe production line is mainly used to produce round pipes of 60 to127 mm, wall thickness of 1.5 to 4.5 mm and square pipes, and can also produce square pipes of 50×50-100×100mm and thickness of 1.5 to 4.0mm under the corresponding raw material conditions Tube. On the basis of digesting and absorbing similar equipment at home and abroad, each single machine of this production line is innovatively designed in combination with my country's national conditions. The operation and maintenance are convenient, the design level and manufacturing quality are in the leading position in the country, and the structure and precision have reached the level of the units introduced in recent years. This unit has high processing quality and assembly accuracy, and adopts a reasonable roll pass, which can produce electric welded steel pipes with relatively high precision.
1. Product process:
Coil Loading → Uncoiler → shear and Welding → Horizontal Spiral Accumulator → Forming, HF welding, Cooling,welding polish, Sizing, Rought straightening → cutting saw → Straight machine → milling head machine → check → Packing → Storage
2. Main parameters of each unit.
1) double cone Hydraulic Uncoiler
The uncoiler is of the structure of one cone. It contains two main parts: main body and the fixed base. The main body is equipped with pneumatic system to satisfy the needs of expanding, contracting and braking of the mandrels.hydraulic expanding and Pneumatic driving

2) straight head and pinch leveling machine
This unit is main used to lead the new coil steel head feed into the flattener unit after uncoiler unit bring the coil into the working place.
straight head motor power :AC1.5KW
processing pressure:7 Mpa
The leveling unit with 2 roll pinch and 5 roll leveling.
pinch roll diameter: 180mm
leveling roll diameter: 120mm
pinch and leveling motor:15kw
3) Shear and welder
Shear and welder is used to cut the irregular ends of the strips and then connect the strips by welding.

4) Horizontal accumulator
This unit is main include in press& carry material device, accumulator assemble, carry off material unit, electric control unit, feeding device
It is main include frame, electric motor, brake unit, circling direction transfer power axle of the reduce velocity, press & carry roll, pressure air system of guide roll, inspected velocity unit; it can supply the strip steel to accumulator and the mean times it will transfer the carry velocity information to electric control system, when we demand stop carry the material to this unit, it will stop roll to the electric motor and press& carry material roll by the break, and also could adjust the velocity to carry electric motor and the unit carry material velocity.
Accumulator frame assemble: include the electric motor, frame , inner circle roll, out circle roll and pressure roll. It can be used to storage the strip steel material from press& carry unit and it could be draw from the center send-off material roll.
Send-off material device: include frame, guide direction rolls, guide out roll of high or lower place. It can carry the strip steel to shape system and send the carry out material velocity information to electric control device.
5) Forming & Sizing Mill
Forming & Sizing Mill adopts roller type forming principle and high-frequency induction welding. The strip is fed into the forming machine by the feeding device in the mill and the forming roller continuously rotate and press the strip into the required shape. Due to the skin and the kindred effect, the high-frequency current is concentrated on the weld joint that is heated rapidly and reaches the welding temperature. The tube seam is welded under the
Forming speed:15-60m/min
Finish round pipe diameter:60-127mm
Finish round pipe thickness:1.5-4.0mm
Finish square pipe size:50x50-100x100mm
Finish square pipe thickness:1.5-4.0mm
6) cold saw
used to precisely cut the pipe to length automatically under the condition that the pipe
continuously delivered from the mill at high speed.
Round pipe diameter:Φ40-130mm,thickness:1.2-4.0mm
7) Runout table
After cutting,the finish pipe running on the transit table,then use the automatic unit make it into stack desk
8) Automatic stacking machine (only for square pipe)
