Abstract
A cover flange for pipe installation is disclosed. According to an embodiment of the present invention, a pipe-mounting cover flange includes a cover coupled to an upper end of a pipe; And a lug which is formed to protrude from the upper end of the cover and has a fastening hole for fastening the fastening means of the lifting device for lifting up the pipe.
Description
The present invention relates to a cover flange for pipe installation.
The offshore production facilities installed on ships and offshore platforms are equipped with various pipes for oil well sampling, discharge of gravel and sand, and seawater (cooling water) inflow.
For example, in the case of a caisson pipe installed in FPSO (Floating, Production, Storage and Off-loading) or a cutting discharge pipe installed in a drill ship, ) To the bottom of the hull is installed vertically. At this time, the total length of the pipe is approximately 20 to 25 meters, and the weight is approximately 3 to 20 tons.
When these pipes are connected together in a single piece, the technical difficulties and workload are not only considerable, but also the pipe installation work can be very inefficient as the pipe height increases and the risk increases. Therefore, it is preferable to combine several pipes in advance into one assembly pipe, and install them in the hull.
However, it is very difficult to lift a heavy assembly pipe using a lifting device such as a crane, and lift the pipe to mount the pipe on the hull. In Korean Unexamined Utility Model Publication No. 20-2015-0000802 (published on Feb. 25, 2015), a method of fastening and fastening a fastening means directly to a bolting hole formed in a flange of a pipe has been proposed. However, It is not suitable for moving the pipe in the vertical direction.
An embodiment of the present invention is intended to provide a pipe-mounting cover flange that enables a pipe to be easily raised and lifted to efficiently perform the pipe installation work.
According to one aspect of the present invention, a cover coupled to the top of the pipe; And a lug which is formed to protrude from the upper end of the cover and has a fastening hole for fastening the fastening means of the lifting device for lifting up and lifting the pipe.
The cover is coupled to a flange formed on the upper end of the pipe to cover an open portion of the upper portion of the pipe, a coupling hole corresponding to the bolt hole of the flange is formed at a peripheral portion, To the flange.
The lug is provided in a triangular shape, and the fastening hole can be formed at the center of the lug with reference to the center line of the lug.
A bracket may be formed on both sides of the lug to connect the lug and the top of the cover in a diagonal direction so as to correspond to a force acting on the lug when the pipe is lifted up in a vertical direction.
The lugs may be symmetrically formed in pairs at the top of the cover.
The cover flange for pipe installation according to the embodiment of the present invention allows the pipe to be easily raised and lifted, so that the pipe installation work can be efficiently performed.
The effects of the present invention are not limited to the effects mentioned above, and other effects not mentioned can be clearly understood by those skilled in the art from the description of the claims.
FIG. 1 is a cross-sectional view illustrating a configuration in which an assembly pipe is installed on a hull using a pipe-mounting cover flange according to an embodiment of the present invention.
FIG. 2 is a view showing a state where the pipes constituting the assembly pipe shown in FIG. 1 are disengaged.
Fig. 3 is a perspective view showing the shape of engagement between the cover flange and the pipe shown in Fig. 1. Fig.
Fig. 4 is a perspective view and a side view of the cover flange shown in Fig. 3;
Fig. 5 is a perspective view showing another example of the cover flange shown in Fig.
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. The embodiments described below are provided by way of example so that those skilled in the art will be able to fully understand the spirit of the present invention. The present invention is not limited to the embodiments described below but may be embodied in other forms. In order to clearly explain the present invention, parts not related to the description are omitted in the drawings, and the width, length, thickness, etc. of the components may be exaggerated for convenience.
