Oil and gas transmission pipe rolling machine is our new patent product,it includes below technology:
1.upper roller use back deformation method to eliminate the deflection in manufacturing process
for the presssure mode at the both ends of the upper roller adopt more then one set of the oil thank ,oil cylinder fixed, cylinder movements lead roll seat ,in order to effectively use  space ,increase the material utilization, greatly reduce the overall weight of the equipment.
2.when discharge the products ,it is from the inside of the rack without to turnover and reset ,enhanced security .
3.all of discharge of the produts all use the automatic cylinder (anther patent technology of our company  ) suitable for line production.
