Steel Pipe Making Machine Tube Induction Welder Solid State High Frequency Welder

Introduction

It is designed for induction (contact) welding of straight seam steel pipes. The high-power capacitor bank C and the inductance coil L form a current-type parallel booster resonant circuit. This circuit ADAPTS to the high-frequency welded pipe with low load impedance and does not need an output transformer. It not only improves the efficiency but also increases the reliability of the whole machine.

Technical features
1, Real all-solid-state IGBT power regulation and converter control technology, the use of unique IGBT soft-switching high-frequency chopping and amorphous filtering power adjustment, high speed and precision soft-switching IGBT inverter control, 100-800khz / 3-300kW product application.
2. Adopt imported high-power resonant capacitor to obtain stable resonance frequency, effectively improve product quality and realize the stability of the welding process.
3, With high frequency chopped power regulation technology to replace the traditional thyristor power regulation technology, to achieve microsecond level control, greatly realize the rapid adjustment and stability of the welding pipe process power output, the output ripple is minimal, the oscillation current is stable, to ensure the smoothness and linearity of the weld, become the first choice for high precision welding pipe.

Power supply cabinet

The DC power unit includes rectification, filtering, and logic control parts.
Independent voltage and current display and control system - independent control of the welder even in the event of a problem with the central console.

Center Console

Equipped with LCD screen, power adjustment, motor speed adjustment module, fully realize the centralized control of welded pipe production line.

Inverter cabinet

The inverter part consists of a single MOSFET inverter unit in parallel, and each unit has a self-diagnostic capability for easy installation and maintenance.

Water heat exchanger

Composition: plate heat exchanger, water tank, water pump and electrical control part

Rectifier isolation transformer

The rectifying transformer is the input rectifying part of the equipment. The power supply voltage is reduced from 415V to 200V, which ensures the stable power supply of the equipment and plays the role of isolation to the power grid.

FAQ

Q: Are you a manufacturer?
A: Yes, we are a manufacturer. We have 4 factories ( Machining, Assembling, Heat treatment, and Moulding ). We also have our own R&D department. Welcome to visit us.
Q: What kind of payment term do you do?
A: We do T/T.
Q: What info do you need before giving me the price and proposal?
A: Since we design individual machines based on our customer's requirements, we need your desired products' basic dimensions, including all the pipe diameter(or tube length), thickness range, usage, raw material steel grade, coil weight, and degree of automation.
Q: What should I do if I just start a new business?
A: Contact us immediately, we provide a free consultant for pre-sales service. Also, we can help you solve the raw material (steel coil) purchase, worker training, international market price, and more.
Q: How do you do QA?
A: We have a special team to do strict QA, this is one of our strengths:
(1)Every gearbox will be tested for 8 hours with oil inside to guarantee there is no leak.

(2)Every shaft will be inspected for centering jumpiness.
(3)Every roller will be checked to make sure it's in the range of tolerance critical parts will be inspected for all dimensions.
Q: Why I should choose you? what are the differences between you and other Chinese suppliers?
A: We are concentrating on pipe-making machines for more than 20 years. We have constructed many steady trading partners in Asia, Africa, the middle east, Europe, and South America throughout the years. Our innovative designed production line and every single unit of the production line are economical and practical.
