④ In order to meet the market needs of large diameter thick wall steel pipe, on the basis of the original patent product thermal expansion machine, our engineers Fu Bingzhong invented the four cylinders hydraulic two step-propulsion pipe expanding machine, cylinder two-step relay propulsion has reduced half of the expanding machine oil cylinder stroke, solved the processing limitation of oil cylinder stroke length from technology, greatly reduced the equipment cost of 1/3 1/2, and changed the original parallel thrust into frame type action point thrust, strengthened the stability of the equipment, improved the degree of freedom on the expanding machine equipment in operation, enhanced the reliability and the production efficiency of the equipment. At present, the thermal expansion machine unit hydraulic type two-step propulsion pipe machine has been successfully developed CNC pipe expanding machine, have realized intelligent PLC programming control, touch screen operation, remote..
