The machines are for steel straight-line-seam and seamless pipes (from 8 to 24 m length with external diameters 219-1420 mm) cold bending in field conditions.
The machines can be used for pipelines construction on pipe-welding-stations. Bending is to be by pipes rolling by forming template (shoe) with bending bed and hydraulic-cylinders system. The machines are to complete by general angle meters. Supply of digital meters is possible, ac-cording to additional Purchase order.
It is necessary to use the GT1022 pipe bending machines with mandrels in a complete for bend from spiral-seam and factory-furnished insulation pipes produce. In addition the mandrels allow reduc-ing embossing-generation up to its absence and securing maintenance of out-of-roundness of pipes in tolerances.
For definition limit bending tube thickness subject to strength of pipe material you can use the graphs: GT1022
