Abstract

Изобретение относитс  к нефтепереработке, а именно к процессам перекачки в зких нефтепродуктов по трубопроводам с попутным обогревом. Цель изобретени  - повышение надежности. Обогреваемый трубопровод содержит секции труб 1, 2, стыкуемые посредством диффузорного 3 и конфузорного 4 раструбов, фланцев 5 и патрубка 6. Дл  обогрева нефтепродуктов выполнены внутренние трубки 8 с конусной спиралью 9, расположенной в диффузорном патрубке 3 и содержащей не менее четырех витков, из которых крайние витки 10, 11 соединены соответственно с диффузорным раструбом 3 и патрубком 6. 1 з.п. ф-лы, 2 ил.The invention relates to oil refining, in particular to processes for transferring viscous oil products through pipelines with associated heating. The purpose of the invention is to increase reliability. The heated pipeline contains sections of pipes 1, 2, joined by diffuser 3 and confused 4 sockets, flanges 5 and nozzle 6. To heat oil products, internal tubes 8 are made with a conical helix 9 located in the diffuser nozzle 3 and containing at least four turns of which extreme turns 10, 11 are connected respectively with the diffuser socket 3 and the pipe 6. 1 Cp. f-ly, 2 ill.
