Energy and material saving technologies for construction of main pipelines for oil and gas transportation

Based on the study and analysis of technologies technical means for transporting oil gas through main pipelines, energy material-saving methods their construction are scientifically substantiated. A method designing trunk pipelines with variable wall thickness is proposed, which possible under conditions current interstate standard GOST 31447-2012. The technique based use mathematical statistical modeling a multifactor experiment processing experimental data. results model, optimal parameters were found, new solutions proposed that would significantly reduce material consumption laying pipes during one run, i.e. between transfer pumping stations.
