METHOD FOR REPAIRING DEFECTIVE PIPELINE SECTION OF ABOVEGROUND GASKET Russian patent published in 2017 - IPC F16L1/24 

FIELD: machine engineering.

SUBSTANCE: cradle housing rise with a pipeline and installation of the anti-friction cushioning material between the base cradle housing surface and the upper surface of the table-raft foundation, are carried out in front of the defective pipeline part notch by the lifting mechanism. Then, pipe fixing is performed on the supports on the both sides of the cut places by the clamping devices, and defective pipeline section clipping is performed. The installation of the repair pipeline section is made by the welded joint means with the coaxial pipe ends, after bringing the pipeline ends in alignment with the clamping devices and the load-lifting mechanism. The clamping devices are designed as modular units comprising the upper and the lower portions consisting of steel profiles rigidly interconnected in the transverse direction.

EFFECT: preventing the loose pipe end movement adjacent to the cutting site in the pipe metal cooling process.
