Characteristics to be maintained in the production of pipe e

Characteristics to be maintained in the production of pipe expander:  

Interchanged in expanding the production control of intermediate frequency power supply will steel tube heated to the required temperature and constant, especially in the thermal expansion of high alloy steel pipe, more can reflect the system to adapt to the nature of the thermoplastic deformation temperature region narrow, effectively avoid the human factors caused by the alloy steel pipe burnt (high temperature) produced by the decline in the quality of steel pipe products and mold scrapped,  At the same time, the phenomenon of rod or die fracture caused by thrust increase of thermal expansion unit due to too low temperature is avoided.  Ensure the smooth operation of thermal expansion unit and reject the unstable factors.  

The medium frequency power supply with constant temperature heating thermostatic system as a whole, thus ensuring thermal expansion pipe heating is always in a state of constant temperature, compared with the manual operation of steel pipe heating, energy-saving health, simplify the operation procedures, reduce the labor costs, can achieve a operators at the same time monitoring the ten more normal production expansion tube expanding unit,  And can be programmed by pressure, speed, temperature overload protection.  In the expansion production due to the expansion unit pressure is too high and caused by the unstable factors.  

Each unit is equipped with two temperature measuring points for automatic temperature control. According to the preset heating temperature of different grades of steel pipe, the heating temperature of steel pipe to be expanded can be selected and kept constant. Real-time display and record can be carried out, and real-time curve and historical curve of heating temperature parameters can be printed and saved.  At the same time, it will automatically store the relevant temperature, time, working pressure, speed and other related information to ensure the traceability of data.  

Specification: diameter φ60 ~ φ1420mm, wall thickness 3 ~ 120mm, length 3 ~ 24m.  Can be expanded to various materials of steel pipe (such as P91-92/T91-92, Q235, Q345, 45#, A106B-C, 12CrMoV).  

Intermediate frequency pipe expanding machine equipment mainly includes: machine base, main oil cylinder support plate (including main oil cylinder), movable push plate, front support plate, automatic feeding structure, feeding roller table, mold support, intermediate frequency coil adjustment frame (including intermediate frequency heating coil), intermediate frequency power supply, electrical control system and so on.  

The company mainly according to the needs of customers to produce steel pipe diameter and wall thickness to the customer needs of the expansion machine, so that the expansion machine manufactured in the production process can maintain the advantages of equipment in the work to maintain constant temperature.  Our company mainly produces the pipe fitting equipment required by customers: pipe expanding machine, elbow machine, tee machine, press, pipe bending machine, beveling machine and so on.
