Determination of safety degree of underwater crossings of gas-pipelines in difficult engineering-geological conditions

Article preview

Reliability and safety are the most important requirements for pipeline transport. The underwater pipelines exploitation analysis based on the last 10 years data shows that the reasons of refusals normally are different force factors, to which concern internal pressure of gas, inadmissible bend on roughnesses of a water bottom relief, random dynamical influences of boat anchors, resonant fluctuations under influence of a stream during washouts of a bottom, erosive process at the bottom and coasts etc.

Application of anti-turbulent additive in pumping diesel fuel through the main pipelines of OJSC AK Transnefteprodukt

Article preview

Aspects of practical application of antiturbulent additive for diesel fuel transportation by main pipelines are studied. Experimental data on pilot and industrial transportation of diesel fuel with Nekadd-447 anti-turbulent additive are analyzed.
