Elbow Machine development history and trends:
In 1970s,the performance of Elbow Machine is further improved.at the meantime,the bend pipe inner tire is manufactured successfully which is match up with Cold Elbow Machine.It can produce large-caliber oil-gas pipeline.the largest pipe diameter can reach to 1524mm.In 1960s,America can use the Hydraulic elbow machine to bend the thickness 6-30mm steel pipes.
Nowadays,some developed countries can produce vertical Hydraulic. Such as USA,canada,germany and so on.The inner tube can devide into pneumatic type and hydraulic pressure type two kinds. Since Hydraulic inner tire is a compact structure and smooth and reliable hydraulic transmission,it can ensure the pipeline prefabrication in processing does not deform.the advantages of pneumatic inner tire type are fast speed and high efficienty for bending pipes.since the system is not stable and controlled,it need an air compressor to operate the machine.
With the development of the technology,there are various elbow machine types.the performance of elbow machine are improved.especially the application of PLC(programmable logic controller) microcomputer singlechip advance AC servo new Hydraulic components and Hydraulic technology make the elbow machine function more perfect.the CNC pipe bender will replace the traditional pipe bender and become a modern tube bending as main equipment.

Hei Yan is specilized in manufacturing hydraulic elbow machine, pipe bending machine, pipe expanding machine,hydraulic press, cold draw tee machine, induction heating equipment.
