FIELD: erection of pipe lines. SUBSTANCE: in erecting pipe lines for successive transfer of petroleum products of different densities, sections of pipe line are laid in wave-like pattern in vertical plane at constant amplitude exceeding the diameter of pipe line. Length of wave of pipe line is preset taking into account bending stresses. EFFECT: higher efficiency. 1 dwg
