Description
Изобретение относитс к строитель ству трубопроводов и может быть использовано при строительстве подводных трубопроводов, преимущественно с теплоизол цией.The invention relates to the construction of pipelines and can be used in the construction of subsea pipelines, mainly with thermal insulation.
Цель изобретени - повышение надежности за счет уменьшени числа сварных соединений.The purpose of the invention is to increase reliability by reducing the number of welded joints.
Труба дл строительства теплоизо- лированного трубопровода состоит из предварительно изготовленных и сваренных встык одна с другой трубных секций, кажда из которых состоит из расположенных концентрично двух труб диаметр одной из которых соответствует диаметру стро щегос трубопровода , а диаметр другой трубы больше первого. Эти трубы соединены своими концами посредством специальных ци- линдрических промежуточных вставок, приваренных встык к указанным двум трубам так, что вместе с ними образовывают герметичное межтрубное пространство , которое заполн етс тепло- изол ционным материалом. Указанные специальные промежуточные вставки выполнены в виде фитингов V-образной формы, внешнее кольцо которого, приваренное к трубе большего диаметра, имеет цилиндрические и конические участки, а внутреннее, приваренное к трубе диаметром, равным диаметру стро щегос трубопровода, имеет цилиндрический участок.A pipe for the construction of a thermally insulated pipeline consists of prefabricated and butt-welded pipe sections, each of which consists of two pipes arranged concentrically two, the diameter of which corresponds to the diameter of the pipeline being constructed and the diameter of the other pipe larger than the first. These pipes are connected at their ends by means of special cylindrical intermediate inserts, butt-welded to these two pipes, so that together with them they form a sealed annular space, which is filled with thermal insulation material. These special intermediate inserts are made in the form of V-shaped fittings, the outer ring of which, welded to a pipe of a larger diameter, has cylindrical and conical sections, and the inner one, welded to a pipe with a diameter equal to the diameter of the pipeline, has a cylindrical section.
Между двум имеющими V-образную форму сопр гающимис фитингами, которые привариваютс встык один к другому , образуетс полость, обращенна в сторону наружной поверхности трубы и поэтому легко доступна , благодар чему по вл етс возможность обеспечить качественную и однородную тепловую изол цию трубопровода за счет выполнени указанной полости теплоизо- л ционным материалом после сварки фитингов .Between the two V-shaped mating fittings that are butt-welded to each other, a cavity is formed that faces the outer surface of the pipe and is therefore easily accessible, thereby providing an opportunity to provide high-quality and uniform thermal insulation of the pipeline by making cavity heat insulation material after welding fittings.
Процесс строительства теплоизолированного трубопровода включает стадии соединени предварительно изготовленных трубных секций одна с другой на концах, расположенных концентрически двух труб по средством специальных цилиндрических вставок, имеющих продольную образующую часть V- образной формы, приваренной встык к указанным трубам, стадию заполнени теплоизол ционным материалом кольцевого зазора, который хорошо герметиThe process of building a thermally insulated pipeline includes the steps of connecting prefabricated pipe sections to each other at ends located concentrically between two pipes by means of special cylindrical inserts having a longitudinal forming part of a V-shaped, butt welded to these pipes, the stage of filling the annular gap with thermal insulation which seal well

зирован, а также стадии транспортировки указанных трубных секций на рабочую площадку и их последовательного соединени путем сварки.as well as the stages of transporting said pipe sections to the working platform and their successive joining by welding.
На фиг.1 изображена труба, продольное сечение; на фиг.2 - разрез А-А на фиг.1.Figure 1 shows the pipe, a longitudinal section; figure 2 - section aa in figure 1.
Труба содержит трубные секции 1, которые должны привариватьс встык одна к другой дл строительства теплоизолированного трубопровода (на фиг.1 показаны только две сопр гающиес секции).The pipe contains pipe sections 1, which must be butt-welded to each other for the construction of a thermally insulated pipeline (only two mating sections are shown in FIG. 1).
Кажда секци 1 образована из двух концентрически расположенных труб 2 и 3, из которых внутренн труба 2 имеет наружный диаметр стро щегос трубопровода. Указанные концентрически расположенные трубы 2 и 3 затем соедин ютс одна с другой у своих концов посредством двух идентичных специальных цилиндрических фитингов 4, которые соедин ютс встык к указанным трубам посредством сварных швов 5 и 6.Each section 1 is formed of two concentrically arranged pipes 2 and 3, of which the inner pipe 2 has an outer diameter of the pipeline under construction. Said concentrically arranged pipes 2 and 3 are then connected to one another at their ends by means of two identical special cylindrical fittings 4, which are butt-joined to said pipes by means of welds 5 and 6.
Указанные специальные фитинги 4 имеют свою продольную образующую в форме горизонтально установленного кольца, в котором внешнее кольцо 7 присоедин етс встык сварным щвом 6 к трубе большего диаметра 3, а своим другим концом посредством промежуточного кольца в форме расшир ющегос конуса 8 присоедин етс к нижнему цилиндрическому кольцу 9, которое в свою очередь соедин етс встык посредством сварного шва 5 к внутренней трубе 2.These special fittings 4 have their longitudinal forming in the form of a horizontally installed ring, in which the outer ring 7 is joined end to end with a butt weld joint 6 to the pipe of larger diameter 3, and with its other end through the intermediate ring in the form of an expanding cone 8 9, which in turn is butt-in joined by means of a weld 5 to the inner pipe 2.
Благодар зтому между фитингами 4 и трубами 2 и 3 образуетс герметизированна полость 10, котора заполн етс теплоизол ционным материалом. Указанное заполнение может производитьс как нанесением теплоизол ционного материала на внутреннюю трубу 2 перед ее внесением внутрь внешней трубы 3 и привариванием специальных фитингов 4, так и посредством внесени специальных смол внутрь полости 10 через соответствующие отверсти , которые затем герметизируютс .By this, a sealed cavity 10 is formed between the fittings 4 and the pipes 2 and 3, which is filled with a heat insulating material. This filling can be done by applying heat insulating material to the inner pipe 2 before inserting it into the outer pipe 3 and welding the special fittings 4, and by introducing special resins into the cavity 10 through the corresponding holes, which are then sealed.
Дл образовани трубопровода трубные секции или стержни 1, изготовленные указанным образом, последовательно соедин ютс встык одна с другой посредством кругового сварного шва на кра х (фиг.2) цилиндрических колец 9 указанных специальных фитингов А.In order to form the pipeline, pipe sections or rods 1 made in this way are butt-wired in series with each other via a circular weld seam on the edges (Fig. 2) of cylindrical rings 9 of said special fittings A.
Внешние полости, которые образуютс между фитингами 4, привариваемыми один к другому, также заполн ютс теплоизол ционным материалом.The external cavities that are formed between the fittings 4 welded to one another are also filled with heat insulating material.
