1. Spiral accumulator unit


This unit is main include in press& carry material device, accumulator assemble, carry off material unit, electric control unit.


(1) press & carry material 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.

(2) 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.

(3)  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.

(4)technical parameters:

working style: change circle

advantage:storage material more, no strike to strip steel suface.

steel coil thickness:4mm


storage dia:5.0m

carry material going velocity:Vmax=240m/min

Pinch form:pneumatic 6Mpa

electric motor power of the press & carry:18.5KW

the electric motor of the accumulator frame :37KW



4.  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 pressure of squeeze rollers. The finished welded tube with required size can obtained after the cooling, sizing and primary straightening.

5. cold saw

The cold saw used to precisely cut all kinds of frame tube automatically. Concerning to using high accurate STD control system and machinery system, this unit has the good precisely dimension advantage, and the machinery transfer best advantage, so the quickly ability and accurate processing,without Burr is this unit advantage.

Rated DC voltage: UdN=450V Rated DC current: IdN=800A

The whole efficiency: η≥85% Output power: Pout>300kW

Designed frequency: f=300~350kHz MOSFET inverter: 120kW×3

Tank circuit output mode: no welding transformer output, secondary resonance



7. Roll Table, Bench & Packing Machine

The finished pipes run along the Roll Table and to be automatically moved onto the Bench. Then simple Packing Machine packs the pipes in hexagon shape.

The simple packing machine contains container and pneumatically driven alignment



8. Roller :

The material :Cr12

The material Cr12 has the advantage of resisting abraded, and the clients can choose it by yourself.

The roller is priced by its weight ,we can calculate the total price of the rollers according to the specification of the welded pipe from the clients.
