EDUCATION MECHANISMS CAVITATIONAL ZONES BY MENAS OF ASPHALTHEN - PITCH - WAX DEPOSITS ON A SURFACE TO A PIPELINES

N work the major factors influencing on are listed formation of APWD. The special attention is paid to a group chemical composition of initial raw materials and mutual influence of separate high - molecular components of oil on structurization in oil syste m at low temperatures. Influence of structural and group composition of oil on the formation mechanism, structure and APWD properties is shown. Ours, researches show that, cavitation can happen not only in pumps, water - wheels and depends on physical and ch emical and rheological properties of mixes high - paraffinic, asphaltic, high - stiffening the crude oil. Such oil form cavitational zones in pipeline transport, in use oil pipelines. formations, structure and APWD properties. Cavitational zones form APWD it i s on an internal surface of a pipe. The working part of a hydrodynamic pipe serves for obtaining high speeds of a stream. Cavitation arises as on the examinee the sample placed in this part of a pipe and on walls of the pipe. In article the general informa tion about cavitation is resulted and at present and conditions known at present and consequences of its occurrence, as hydraulic phenomenon are listed
