A clamp for pipe insulation repair operations

Abstract

The utility model relates to pipeline maintenance equipment technical field provides a clamp for pipeline thermal insulation layer repair operation, contains support pipe, and the outside surface of support pipe is used for and the inside surface of sleeve pipe abuts; At least one axial fracture is provided on the support pipe; Locking structure, locking structure sets up at axial fracture department, locking structure can lock or unlock, thereby makes the end of support pipe located axial fracture both sides mutual connection or separation; Support column, support column sets up in the inside surface of support pipe, and the end of support column is used for and the outside surface of the pipeline to be maintained abuts with away from support pipe. The utility model can overcome the deficiency that the axis of sleeve pipe is easy to shift relative to the axis of the pipeline to be maintained in the prior art pipeline thermal insulation layer repair technology, thereby can have the negative influence to the foaming quality of hard foam, and further lead to the decrease of pipeline corrosion resistance.
