Description

Technical Field

[0001] The utility model relates to the technical field of pipe processing, in particular to a pipe supporting device. Background Art

[0002] When the pipe is stretched, it is inevitable to fix a position on the pipe. At present, the fixation of the pipe is mainly done by clamping. When clamping the pipe, fillers need to be used inside the pipe to form internal support to prevent the pipe from being flattened when the clamp is clamped from the outside.

[0003] Most existing fillers are solid rods that form internal support for the pipe. Ideally, the outer diameter of the rod is processed to the same as the inner diameter of the pipe, and an interference fit is achieved. Different specifications of rods need to be used to support pipes of different specifications, which is inconvenient. After stretching, it is also not easy to pull the rod out of the pipe.
