High frequency welding tube mill
High frequency welding tube mill is designed to make various shape pipes like square pipe, round pipe, oval pipe and other special shape pipes. The tube mill takes advantage of high frequency welding system and cold roll forming principle to make pipe from the thin sheet. The tube raw material could be various types like carbon steel, metal like Q235 and others.
Tube Mill Working Process:
{Steel Tape}→→ Single-arbor un-coiler →→Strip-head Cutter and welder→→ Spiral Accumulator→→Forming section(Flattening unit +Main driving unit +Forming unit +Guide unit +High frequency induction welding unit +squeeze roller)+ De-burr frame →→Cooling unit →→ Sizing unit and straightened →→Flying saw under computer-control →→ Run-out table→→straightening
High frequency working principle:
For welding part, it makes full use of two sciences-high-frequency current Skin-Effect and Adjacency Effect to make the current concentrate on the edge, then the temperature will reach to the point of welding. Then we can make the sheet to pipe by rolling and make the edge melting to one.
HF Welder technology has the following features:
1.It supports many kinds of material like carbon steel, GI and others.h
2.One machine could make a large range of pipe sizes by changing mold.
3.One machine could be used to make square pipe, round pipe by changing mold.
4.High working efficiency but low energy consuming: the power is 200KW TNGP.
5.The pipe made by this kind of machine could be used in many areas like water tube, wire pipe and others.Steel Pipe Production Line
Description:
The advent of steel pipe production line technology and its development at the half centry of 19th centry, at the beginning, rolling pipe mill will roll strip to round shape and then weld the seam by butt. However, now we have improved the technology, we take High frequency welder to make non-stop production of steep pipe. With this tech add in, our machine could reach working speed at 90m/min. For example, one ton coil could be used to make square pipe at lenght of 6m and size at 20x20x2mm, 132 pipes. And for producing those pipes, our machine only needs 8 minutes. According to those data, our machine is fitting for those who need to run factory of steel pipe. Even if you need huge amount pipes, our steel pipe production line can help you make in a few hours.
Question: for high speed machine will consum electricity?
Normally speaking, this kind of steel pipe production will consum electricity a lot. For ours, we have developed long time and now we have found the solution for this. Our machine now could work in high speed but consum less electricity. Meanwhile our machine is fully automatic, one person could run this machine. And when using, it is low noise, and high efficiency.
Equipment of steel pipe production line:
Key elements of continuous mandrel rolling process.
The continuous mandrel rolling process is the soul of rolling mill. By rolling little by little to chanage the shape of stripe to round and then to square or rectangle or oval. So the quality of roller decides the using life of steel pipe production like. For our machine, we use the best material of roller to make sure the machine which could be used more than 20 years without any problem. Please check mould details in mould tab.
High frequency welding method:
Following the developement low frequency electric resistance weldeding procecss, the 1960 saw the introduction of HF welding process as alternative. This welding technology since developed then wide spread.The process involves the application of a high-frequency alternating current in the range 200 – 500 kHz, with the tube forming and energy input operations being performedby separate units. This welding method again simultaneously utilizes pressure and heat in order to join the strip edges of the open-seam tube together without the addition of a filler metal. Squeeze and pressure rolls in the welding stand bring the edges of the open-seam tube gradually together and apply the pressure.
Brief Introduction of Spiral Welded Tube Machine:
Spiral welded pipe machine is used to big diameter pipes by spiral welding method. By decoiler to uncoil and level the steel coil, and send the strip to forming machine by certain angle, then bend the pipe by certain angle based on three-roller forming principle, at last weld the spiral welding seam by the submerged arc welder. It is also called SSAW pipe mill.
Working process of Spiral Welded Tube Machine:
Decoiling--> remove the unneat and unstraight part at the beginning--> feed coil to machine--> Vertical roller to fix the coil and weld two coils together--> forming station-->inner and outside welder system-->flying and tracking cutting saw system-->runout table
Supported material:
Galvanized Sheet, carbon steel coil and others.
Diameter range:160mm-3250mm
Thickness range:2-10mm

Main function of each part of Spiral Welded Tube Machine:
1. Decoiler system firstly is used to open and feed the first edge of coil to the strip edge joining system. Meanwhile this part also bends the trailing edge of the coils.
2. Side guide rollers are designed to feed the coil in the correct position from the decoiler to the forming section. And the pivot line roller and the cross side rollers are positioned by the hydraulic cylinders; the position will not be changed. Its functions are fixing the coil. And there are also some non-pivot rollers which are moveable for eleiminating the minor movements of the stripe.
3. For leveling and make sure the input coil straight, there are some non-driven rollers to level coil stressed by the hydraulic cylinders.
