Special pipe fitting equipment for pipe fitting processing

Special pipe fitting equipment for pipe fitting processing  

Special pipe fitting equipment for pipe fitting processing mainly includes: pipe bending machine, tee machine, elbow machine, press machine, bevel machine, pipe expanding machine, etc.  The above pipe fitting equipment is used to produce the pipe fitting required by the examination through the supporting mold.  

Performance and characteristics of the pipe fitting equipment: reasonable structure, low noise in the production process, energy saving and environmental protection, high production efficiency.  The pipe fitting equipment adopts PLC control system. If the pipe fitting equipment fails in the production process, the system will show, which is convenient for the operator to deal with the fault in time.  

There is no specific model of pipe fitting equipment, we will make it according to customers' main requirements.  Our company will provide each customer with structural drawings, design drawings, working principles, technical parameters and pre-sales and after-sales service.  

Generally, the diameter of pipe fitting equipment is 21-1620 and the wall thickness is 3-120. Some pipe fitting equipment has a diameter of 21-630 and a wall thickness of 3-100.  Medium frequency bend characteristics  

1. Medium frequency bend adopts the power supply with vertical external characteristics, and the positive polarity is used when DC (the welding wire is connected to the negative electrode).  

2. The medium frequency elbow is generally suitable for the welding of thin plate below 6mm, with the characteristics of beautiful weld shape and small welding deformation  

3. The protection gas is argon with a purity of 99.99%.  When the welding current is 50-50A, the flow rate of argon is 8-0L /min, and when the current is 50-250A, the flow rate of argon is 2-5L /min.  

4 welding arc length, welding ordinary steel, with 2~4mm is the best, and welding stainless steel, with ~3mm is the best, too long protection effect is not good.  

5. In order to prevent the appearance of welding pores for medium frequency elbow, the welding parts should be cleaned up if there is rust and oil pollution.  

6 tungsten from the gas nozzle protruding length, with 4~5mm is the best, in fillet welding and other shelter is poor place is 2~3mm, in the deep slot is 5~6mm, the nozzle to the working distance is generally not more than 5mm.  

7. In order to prevent the back of the bottom bead from being oxidized, gas protection should be implemented on the back of the if elbow butt.  

8. Wind protection and ventilation.  In windy places, please take measures to screen, and in the indoor should take appropriate ventilation measures.  

9. In order to make argon well protect the welding pool and facilitate the welding operation, the center line of tungsten pole and the workpiece at the welding place should generally keep the Angle of 80~85°, and the Angle between the filler wire and the workpiece surface should be as small as possible, generally about 0°.  

The Angle between surfaces should be as small as possible, generally about 0°.  1871-1834.
