PIPELINE TRANSPORT Russian patent published in 2005 - IPC

FIELD: pipeline transport.

SUBSTANCE: pipeline transport has inner pipe whose at least one flexible wall is provided with at least one movable diaphragm in order to damp gas pressure oscillations. The density and pressure inside the damper space and main pipeline should be as follows ρ₁=ρ₂, p₁<p₂ where ρ₁ and p₁ are density and pressure of gas in the space of damper and ρ₂ and p₂ are density and pressure of gas in pipeline, in kg/m3 and Pa, respectively. The total area of the diaphragm shell is determined from the formula where S is the total area of the diaphragm shell, m², F is the area of the cross-section of the main pipeline, m², m is the mass of the unit area of diaphragm, kg/m², l is the length of the main pipeline, m, ρ is the density of gas in the main pipeline, kg/m³, K is the coefficient allowing for the properties of gas in the pipeline (temperature, humidity, and so on) and interpipe space as well as operation factors (service life, efficiency of piston machine and others), K>1.

EFFECT: prolonged service life of pipeline transport.
