| 摘要 |
FIELD: cleaning of oil and gas pipes from asphaltene-resin-paraffin deposits; oil-producing and chemical industries. ^ SUBSTANCE: proposed method includes pulse action of air flow of deposits moving along pipe. Air flow is formed by pneumatic pulse generator connected to one end of pipe. Air flow is generated at velocity head of from 0.05 to 0.25 Mpa in form of pulse at duration not exceeding 0.1 s. ^ EFFECT: enhanced efficiency of cleaning; increased productivity. ^ 2 cl, 2 dwg |
