12000 mm Length Specialized oil &gas plate rolling machine for small diameter steel tubes
With the development of petroleum and natural gas industries, avoid too many welding seam is an important step in the production efficiency of the pipeline. Under the help of “China Petroleum Pipeline University” ,We have succeeded in producing “PLATE ROLLING MACHINE FOR SMALL DIAMETER STEEL TUBES”
Technology from abroad and research of domestic products specialties are combined in this machine, enables the machine with high efficiency, low energy consumption, easy operation, small investment, etc.You may save a large number of worker and another welding equipment .
Its unique advantages as following:
1. Minimum rolling diameter for cold bending is 1.25 times of plate thickness.
2. Adopt anti-deformation technology to eliminate the deflection of top roller when
rolling small diameter steel tubes, with high rolling accuracy.
3. Straightness accuracy of finished cylinders is controlled in 1/2000.
4. Central distance between lower rollers is adjustable for pre bending and rolling.
5. Adopt auto aligning device to effectively prevent misalignment.
6. Rolling technology is calculated and controlled by computer with automatic rolling Process
