Abstract
The utility model discloses a petroleum platform pipeline dual-layer protective pipe. The petroleum platform pipeline dual-layer protective pipe comprises two arc sleeves, wherein the bottom of each arc sleeve is provided with a semicircular support assembly; the two semicircular support assemblies are in butt joint so as to form a fixed base; the two arc sleeves are connected so as to form a protective pipe body; the central part of the inner part of the protective pipe body is additionally provided with a glass reinforced plastic sleeve; an anticorrosive layer is coated on the inner surface of the glass reinforced plastic sleeve; the glass reinforced plastic sleeve and the arc sleeves are connected through reinforcing steel bar supports. The petroleum platform pipeline dual-layer protective pipe disclosed by the utility model has the beneficial effects that the protective pipe body consisting of the arc sleeves is internally provided with the glass reinforced plastic sleeve additionally, and the anticorrosive layer is coated on the inner surface of the glass reinforced plastic sleeve; the anticorrosive layer can take blocking and buffering effects when the lower position of the joined part between each pipeline and a platform is collided externally or corroded, and exposed pipelines of an offshore petroleum platform can be protected; the service lives of pipelines are prolonged; the normal transportation of the petroleum pipelines is ensured effectively.
Description
Technical field
The utility model relates to a kind of petroleum pipeline pipe fitting, relates in particular to the double-deck pillar of a kind of oil platform pipeline.
Background technique
Offshore platform generally refers to above tide and has a kind of truss structure of level table, for example, for carrying out manufacturing operation, offshore oil platform.Its form has a formula, guy wire formula and gravity type etc., and stake formula platform wherein consists of cushion cap and pile foundation, and pile foundation has timber, piling bar and reinforced concrete pile etc.At present, a lot of pipelines are arranged on offshore oil platform, pipeline need be under platform penetrates into platform, and the intersection of pipeline and platform is not easy to fix very much, and much pipeline is arranged side by side together, not only impact construction, and pipeline itself also is easy to impaired.Thereby, the reinforcing pipe fitting that need to meet specific environment is fixed pipeline and platform, if can only utilize some simple supporting structures to be fixed, comparatively bother on the one hand, caused a large amount of work, the most important thing is, a lot of pipe fittings directly engage with pipeline external surface, because pipe fitting is thinner, are positioned at the low level external impact of pipeline and platform junction point if run into or while corroding, the stability of pipeline can be directly affected, normal transportation work can't be guaranteed.Therefore, for above aspect, need to make rational improvement.
The model utility content
The purpose of this utility model is to provide a kind of intensity that has interior outer double-layer structure, can strengthen pipeline and platform mating face, the double-deck pillar of oil platform pipeline simple in structure, that be convenient to installation, to solve many deficiencies of prior art.
The purpose of this utility model is carried out specific implementation by the following technical programs:
The double-deck pillar of a kind of oil platform pipeline, comprise two arc shrouds, and each arc shrouds bottom is with a semicircle supporting component, and two semicircle supporting component docking form a fixed base; Two arc shrouds are joined and are formed the pillar body, and a glass reinforced plastic sleeve is set up in pillar body interior center, and this fiber glass reinforced plastic cover pipe internal surface applies one deck anticorrosive coat, between glass reinforced plastic sleeve and arc shrouds, by Steel bar rack, are connected; The vertical height of described glass reinforced plastic sleeve equals the twice of arc shrouds vertical height.
Be positioned at each arc shrouds end a vertical stiffening rib is set respectively, a screw is offered on described vertical stiffening rib top.
The beneficial effect of the double-deck pillar of oil platform pipeline described in the utility model is: by the pillar body interior be comprised of arc shrouds, set up a glass reinforced plastic sleeve, and this fiber glass reinforced plastic cover pipe internal surface applies one deck anticorrosive coat, be positioned at low level external impact or when corrosion of pipeline and platform junction point if run into, can play the effect that stops and cushion, can protect the outdoor pipeline on offshore oil platform, extend the working life of pipeline; Can adjust according to actual needs petroleum pipeline, can reduce the amount of labour, increase work efficiency, effectively guarantee the normal transport of petroleum pipeline.
The accompanying drawing explanation
Below according to drawings and embodiments the utility model is described in further detail.
Fig. 1 is the structural drawing of the double-deck pillar of the described oil platform pipeline of the utility model embodiment.
In figure: 1, fixed base; 2, arc shrouds; 3, vertical stiffening rib; 4, locating slot; 5, chassis; 6, glass reinforced plastic sleeve; 7, anticorrosive coat; 8, Steel bar rack.
Embodiment
As shown in Figure 1, the double-deck pillar of the described oil platform pipeline of the utility model embodiment, comprise two arc shrouds 2, each arc shrouds 2 bottom is with a semicircle supporting component, be positioned at that each arc shrouds 2 end arranges respectively a vertical stiffening rib 3 and a screw is offered on this vertical stiffening rib 3 tops, vertical stiffening rib 3 outer surfaces that are positioned at two arc shrouds 2 of the same side mutually are adjacent to and two sleeve pipes are spliced into the pillar body, and two semicircle supporting components docking are a fixed base 1; The some locating slots 4 that distribute of fixed base 1 surface uniform wherein, simultaneously, it is in the same plane that a glass reinforced plastic sleeve 6 and this glass reinforced plastic sleeve 6 bottom surfaces and fixed base 1 bottom surface are set up in the pillar body interior center of two arc shrouds 2 compositions, this glass reinforced plastic sleeve 6 internal surfaces apply one deck anticorrosive coats 7, between glass reinforced plastic sleeve 6 and arc shrouds 2, by Steel bar rack 8, are connected; The vertical height of described glass reinforced plastic sleeve 6 equals the twice of arc shrouds 2, and locating slot 4 wherein is ellipsoidal structure, is positioned at fixed base 1 bottom with chassis 5.
Claims (3)
1. the double-deck pillar of oil platform pipeline, comprise two arc shrouds, it is characterized in that:
Each arc shrouds bottom is with a semicircle supporting component, and two semicircle supporting component docking form a fixed base; Two arc shrouds are joined and are formed the pillar body, and a glass reinforced plastic sleeve is set up in pillar body interior center, and this fiber glass reinforced plastic cover pipe internal surface applies one deck anticorrosive coat, between glass reinforced plastic sleeve and arc shrouds, by Steel bar rack, are connected; The vertical height of described glass reinforced plastic sleeve equals the twice of arc shrouds vertical height.
