Abstract
The present invention relates to a kind of installation method suitable for marine flexible compound internal lining pipe, by using the space of original pipeline, internal lining pipe is installed using drawing guidance mode, so that old pipeline can repeat to recycle.Installation method is mainly carries out pigging to original pipeline first, and pull rope is transmitted with special spherical pig, and then using platform space or construction ship, the flexible pipe that will be wrapped on winch is pulled to the stand-pipe output of another platform with speed faster.Two end connectors are finally installed, then carry out completing to install after suppressing crowded rising.
Description
Technical field
The present invention relates to a kind of installation method of flexible compound internal lining pipe, especially with regard to a kind of installation method of flexible compound internal lining pipe.
Background technology
Flexible compound internal lining pipe is mainly used for a kind of nonmetal pipeline of the etching problem for solving steel pipe, substantially increases the service life of steel pipe, is used with preferable economy and feasibility in offshore oil pipeline field.It is complicated yet with marine operating mode, standpipe is also there is between platform, traditional mount scheme is difficult to complete the installation of flexible compound internal lining pipe, if the problems such as Rig up error also results in leakage.It is a problem for needing to solve so flexible compound internal lining pipe is penetrated into steel duct.
This patent exactly proposes a kind of installation method of flexible compound internal lining pipe in this context.
The content of the invention
It is a primary object of the present invention to provide a kind of installation method of flexible compound internal lining pipe, combined by spherical pig, pull rope and rope traction mode, enable flexible compound internal lining pipe that the terminal of another platform is to be mounted directly to from the initiating terminal of platform, pipe laying barge and the pipelaying work line of specialty need not be used, can directly complete to install using platform existing space, reliability is high, low cost.
The purpose of the present invention is realized by following technical scheme：
A kind of installation method of flexible compound internal lining pipe, it is characterised in that the installation method is comprised the following steps：
（1）According to the corrosion condition of steel pipe, pigging is carried out for several times to whole piece steel pipe using spherical pig, until spherical pig out after, without carry excessive impurity；
（2）Reel is fixed with B platforms, the pull rope one end that will be wrapped in reel is connected with spherical pig, makes spherical pig that pull rope is involved from A platforms using hydraulic pressure；
（3）Winch is fixed with A platforms, pull rope is connected with the steel wire rope one end being wrapped on winch, start reel on B platforms, reclaim pull rope, make pull rope drive steel wire rope to be involved from B platforms；
（4）B platforms steel cord ends are connected with the flexible compound internal lining pipe one end on B platforms nearby ship；
（5）Start the winch on A platforms, reclaim steel wire rope, make steel wire rope drive flexible compound internal lining pipe to be involved from A platforms；
（6）Flexible compound liner pipe joint is installed in A Platform pipes end；
（7）Flexible compound liner pipe joint is installed in B Platform pipes end；
（8）After carrying out suppressing test, installation.
Beneficial effects of the present invention：The present invention is due to using above-mentioned technical proposal, combined by spherical pig, pull rope and rope traction mode, enable flexible compound internal lining pipe that the terminal of another platform is to be mounted directly to from the initiating terminal of platform, pipe laying barge and the pipelaying work line of specialty need not be used, can directly complete to install using platform existing space, reliability is high, low cost.
The present invention will be further described with reference to the accompanying drawings and examples.

Specific embodiment
Below in conjunction with the accompanying drawings and example, the present invention is described in detail.
As shown in figs. 1-7, the installation method of flexible compound internal lining pipe of the present invention, comprises the following steps：
（1）According to the corrosion condition of steel pipe, pigging is carried out for several times to whole piece steel pipe using spherical pig 3, until spherical pig 3 out after, without carry excessive impurity；
（2）Reel 4 is fixed with B platforms 2, the one end of pull rope 5 that will be wrapped in reel 4 is connected with spherical pig 3, makes spherical pig 3 that pull rope 5 is involved from A platforms 1 using hydraulic pressure；
（3）Rope winch 6 is fixed with A platforms 1, pull rope 5 is connected with the one end of steel wire rope 7 being wrapped on winch 6, start reel 4 on B platforms 2, reclaim pull rope 5, make pull rope 5 drive steel wire rope 7 to be involved from B platforms 2；
（4）The end of steel wire rope 7 at B platforms 2 is connected with the one end of flexible compound internal lining pipe 8 on B platforms 2 nearby ship；
（5）Start the winch 6 on A platforms 1, reclaim steel wire rope 7, make steel wire rope 7 drive flexible compound internal lining pipe 8 to be involved from A platforms 1；
（6）Flexible compound liner pipe joint 9 is installed in the steel tube end part of A platforms 1；
（7）Flexible compound liner pipe joint 9 is installed in the steel tube end part of B platforms 2；
（8）After carrying out suppressing test, installation.
The above, only it is presently preferred embodiments of the present invention, not make any formal limitation to the present invention, every any simple modification, equivalent variations and modification made to above example according to technical spirit of the invention is still fallen within the range of technical solution of the present invention.
