TENYES ELECTROTHERMAL EQUIPMENT CO.,LTD(former BAODING TIANYI ELECTROTHERMAL TECHNOLOGY INSTITUTE founded in 1999) restructured in 2002 and is a research, development, manufacture, sales and technical service of high-tech private enterprise, which specialized in manufacturing high frequency, medium frequency and super-audio frequency induction heating equipment.Since its establishment, our company has successfully developed many variety and multi-series products. Most products technology are in the leading position at domestic, and some products reach the international advanced level. Our equipment are widely used in the field of pipe welding,brazing,melting(casting),forging,petrochemical,cookware,heat treatment of metals(quenching, annealing,tempering). Our equipment are popular in domestic market, some equipment are exported to Southeast Asia, Western Europe.

 high frequency steel tube welding machine 

This equipment mainly used in the field of carbon steel tube & pipe welding and special section tube & pipe welding.

The whole set of this equipment consists of rectifying cabinet, inverter cabinet, central control console, step down

transformer, DC speed adjust unit and cooling system.The basic principal of solid state high frequency is that 3-phase AC current voltage is reduced by the step down transformer, and then enter into the rectifying cabinet

through the rectifying, regulating voltage and filtering and become continuously adjustable DC; then enter into 

the inverter bridge(using high-power transistor MOSFET) and become high frequency current, and this high

frequency is supplied to the load tank circuit and then can be used for the induction heating. Inverter tank 

circuit power unit using the modular structure, and each power unit can output above 50KW, the number of 

the power unit is different according to different power equipment.The tank circuit is a kind of series and 

parallel mixing form, no high voltage and no output transformer.

Equipment advantages

1.No high voltage, safety, reliability and high efficiency.

2.The main components are using foreign brands products, such as: IR, IXYS and Siemens.

3.Voltage and Current Double-fed control circuit, stable adjustment, high precision and little interference.

4.Power range 0-100% step-less adjustable, have the advantages of over-voltage, over-current etc.fault protection system.

5.Digital display, simple operating, convenient maintenance.

6.High quality welding, uniform welding seam width, uniform temperature, less burrs in welded tube surface and

 inner.

The main technical parameter
 Model: GGP400-0.25-H

Operating Environment

This equipment is designed for indoor installation, should avoid the rain, frost and snow, sun exposure, it should also 

meet the following conditions:

1.No more than 1000 meters altitude, too high altitude will reduce the air pressure result in bad cooling effect.

2. Ambient temperature -5 ℃ --- + 40 ℃, (less than 0 ℃ should prevent freeze, result in the cooling pipe 

blocked and damaged).

3. Relative air humidity less than 85%.

4. No conductive dust explosion, no gas and steam can rust the metal and damage the insulation.

5. No severe vibration and shock

If does not meet the above-mentioned requirements, the customer should notified our company and we can

consider carefully in the equipment design.

1.Free Fumigation Seaworthy Export Wooden Package
2.Mark as buyer's request 
3.Pallet for fork truck

After-sales Service Provided: Engineers available to service machinery overseas(Round- trip air ticket, food, accommodation, salary covered by buyer)
