METHOD OF MAIN PIPELINE CROSSING STATE DIAGNOSTICS Russian patent published in 2011 - IPC F17D5/06 

FIELD: transport.

SUBSTANCE: proposed method consists in that corrosion rates K₁, K₂ of pipelines at their crossing are measured to be compared with relevant threshold values K₀₁ and K₀₂. In case measured values exceed said threshold values in, at least, one pipeline of the crossing, dangerous state of said crossing is ascertained. Note here that measured corrosion rates for certain time interval are summed up and compared with relevant threshold values S_K01 and S_K02. In case summed corrosion rates exceed relevant threshold values for, at least, one pipeline, dangerous state of said crossing is ascertained.

EFFECT: preventing threat of dangerous state.
