Description
(54) СПОСОБ ВРЕМЕННОГО ПЕРЕКРЫТИЯ ТРУБОПЮВОДА(54) METHOD OF TEMPORARY PIPELINE OVERLAP
II
Изобретение относитс к области трубопроводного транспорта и предназначено дл временного перекрыти сечени трубопровода, в частности , при проведении ремонтных работ.The invention relates to the field of pipeline transportation and is intended to temporarily overlap the cross section of a pipeline, in particular, during repair work.
Известен способ временного перекрыти трубопровода путем закачки в него отверждающейс композиции, например, пенополиуретана до образовани герметизирующего тампона, перекрывающего сечение трубопровода 1.A known method of temporarily shutting off a pipeline by injecting a curing composition into it, for example, polyurethane foam, to form a sealing pad that overlaps the cross section of pipeline 1.
Недостаток известного способа заключаетс в том, что вследствие растекаемости отверждающейс композиции созданный тампон имеет неоправданно большую длину, что усложн ет его извлечение из трубопровода после окончани ремонтных работ.The disadvantage of this method is that due to the spreadability of the curable composition, the created tampon has an unreasonably large length, which makes it difficult to remove it from the pipeline after the completion of repair work.
Известен также способ временного перекрыти трубопровода путем закачки в него отверждающейс композиции до формировани герметизирующего тампона в зоне, огражденной двум упорами, выполненными предварительно из той же композиции 12.There is also known a method for temporarily blocking a pipeline by injecting a curing composition into it before forming a sealing tampon in the zone enclosed by two stops made previously from the same composition 12.
Известный способ обеспечивает возможность регулировки, длины герметизирующего тампона. Однако в св зи с необходимостью выполнени The known method provides the ability to adjust the length of the sealing pad. However, due to the need to
ограничительных упоров он св зан со значительным расходом отверждающейс композиции. Это снижает его эффективность.restrictive stops, it is associated with a significant consumption of the curable composition. This reduces its effectiveness.
Целью изобретени вл етс повышение эффективности способа.The aim of the invention is to increase the efficiency of the method.
Это достигаетс тем, что по предлагаемому способу перед закачкой в трубопровод в комПОЗИ10ПО добавл ют дисперсньш адсорбент с ферромагнитными свойствами, а в процессе закачки в зоне формировани герметизирующего тампона на композицию воздействуют магнитным полем.This is achieved by the fact that according to the proposed method a dispersible adsorbent with ferromagnetic properties is added to a composit10PO before being pumped into the pipeline, and during the injection process a magnetic field is applied to the composition in the zone of forming a sealing tampon.
В качестве дисперсного адсорбента предпочтительно использование металлополимеров, полученных на основе фенолформальдегидной смолы и высокодисперсиого железа.As a dispersed adsorbent, it is preferable to use metal polymers obtained on the basis of a phenol-formaldehyde resin and highly dispersed iron.
