PRODUCT APPLICATION
The model TWG-11A is used to groove pipe that is supported by several different methods. When grooving pipe that is supported with a pipe vise. Mount a chain-type pipe vise onto a stand or workbench. The pipe vise should be mounted flush with, or slightly overhanging, the edge of the stand or workbench. When the tool is mounted on the pipe, the tool must be able to rotate freely around the pipe without being obstructed by the stand or workbench. Position the pipe to overhang the pipe vise by approximately 8 inches, so that the tool can rotate freely. Mount the tool on the pipe, then turn the groove diameter adjustment nut clockwise to lower the upper roll until the tool rests snugly on the pipe. Sometimes the pipe is fixed and can not be removable, but the pipe need to be grooved, in this situation, operators should be confirmed that pipe hangers must be capable of handling the weight of the tool and the manual effort required to operate the tool.
Except above operation, the model TWG-11A can be attached to a power drive using the provided drive shaft adapter. In this way, manual grooving tool will become an electric grooving machine. as this model is using feeding nut to achieve groove depth, so the groove depth can not be adjusted in place by one time, but we have set one graduated circle for customers’ reference. when the feeding nut turns one cycle, the upper roller moves 1.5mm, one graduation mark equals to 0.05mm. customers have to use PI tape to measure whether the groove depth is in place, if not, fix pipe and make groove again.
As this is a light manual tool, customer need to pay more attention when operate and maintain the manual grooving tool,
