✧ Feature
1. Adjustable Roller position is very helpful in adjusting the rollers between the main body so that rollers of different diameter can be adjusted over the same rollers without even buying another size pipe roller.
2. A Stress analysis has been performed on the rigid body for the testing of the load capability of the frame on which the weight of the pipes depends on.
3.Polyurethane rollers are being used in this product because polyurethane rollers are weight resistant and can protect the surface of the pipes from being scratched up while rolling.
4. Pin mechanism is used to pin the polyurethane rollers on the main frame.
5. Adjustable stand is used to adjust the height of the Rigid Frame according to the need and requirement of welding the pipe and according to the comfort level of the welder so that it can provide maximum stability.
