Technical support during repairing of the pipeline air

crossings of gas pipelines

 A mathematical model for determining the static stress-strain state of the pipeline during its lifting and maintenance over emergency supports during the execution of repair work on supports is developed.

​

  The model allows you to calculate the lifting forces for a given level of lifting above the supports and optimally place the minimum number of cranes of pipe-layingers for the safe performance of repair work at the permissible values ​​of stresses in the pipeline.

​

The simulation results were used during repair works on the gas pipeline and allow  to justify the safety of repair cranes on existing pipelines.
