Abstract
The utility model discloses a novel pipeline section for offshore oil platform sea water promotes, including body and the flange of setting at the body both ends, body and flange structure composing as an organic whole, body and flange include: the inner liner that constitutes by the polyester film, the surface coating of inner liner has the resin layer, the spraying has the inner liner of resin layer to follow pipeline axial and vertical outward, and it has carbon fiber resin composite bed to twine, carbon fiber resin composite bed surface is provided with polyester film layers. The utility model discloses satisfy sea water transport and seawater lift pump work, promote the reliability of sea water pipeline to have higher anti tensile strength and anti bending strength, it is biological that seawater corrosion resistance, pipeline are difficult for adhering to the sea.
Description
Technical field
The utility model relates to sea water pipe, particularly a kind of novel pipeline section for offshore platform seawater lift.
Background technique
Along with developing by leaps and bounds of offshore oil, creep into and constantly increase with production platform quantity, platform adopts cooled with seawater equipment, so platform is all furnished with sea water pump, sea water pump is positioned at b.s.l. work, by sea water pipe by more than seawater lift to deck.Sea water pipe is made up of some pipeline sections, can not only carry seawater, can also bear vibration during weight and the sea water pump running of bottom sea water pump.Sea water pipe adopts metallic material manufacture, and long-term work, in briny environment, causes serious corrosion, and is attached with marine growth, periodic replacement of having to.Platform was once attempted using alloy pipeline in recent years, but still there is etching problem, and use Langaloy pipeline costly, platform is difficult to bear; Also once attempted adopting carbon fiber or glass steel pipeline, but existing carbon fiber and fiber reinforced plastic pipe adopt bonding form with Flange joint, can not meet seawater lift pump job requirement.Therefore in the urgent need to improving seawater lift pipeline, to reach the effect of corrosion-resistant and low maintenance expenses.
Model utility content
The purpose of this utility model overcomes deficiency of the prior art, and provide a kind of safe and reliable, intensity is high, the novel pipeline section for offshore platform seawater lift of seawater corrosion resistance.
In order to solve the problems of the technologies described above, the utility model provides a kind of novel pipeline section for offshore platform seawater lift, comprise body and the flange being arranged on body two ends, described body and flange are structure as a whole formation, described body and flange comprise: the inside liner be made up of mylar, the surface spraying of described inside liner has resin layer, described inside liner outer pipeline axial and the longitudinal direction being coated with resin layer, be wound with carbon fibre resin composite bed, described carbon fibre resin composite bed surface is provided with laminated polyester film.
The beneficial effects of the utility model are:
1, the utility model adopt body and flange one-body molded, not only meet seawater conveying, meet seawater lift pump work simultaneously, promote the reliability of sea water pipe;
2, the utility model adopts carbon fibre material, lightweight, cost is low, easy for installation, have higher tensile strength and flexural strength, and a seawater corrosion resistance, pipeline not easily adheres to marine growth.

Accompanying drawing marks: 1, body; 2, flange; 3, inside liner; 4, resin layer; 5, carbon fibre resin composite bed; 6, laminated polyester film.
Embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
As shown in accompanying drawing 1 to 3, a kind of novel pipeline section for offshore platform seawater lift, comprises body 1 and is arranged on the flange 2 at body 1 two ends, and described body 1 and flange 2 are structure as a whole formation; Described body 1 and flange 2 are that carbon fiber is once Wrapping formed, and binding resin solidify to form; Described body 1 and flange 2 comprise: the inside liner 3 be made up of mylar, the surface spraying of described inside liner 3 has resin layer 4, described inside liner 3 outer pipeline axial and the longitudinal direction being coated with resin layer 4, be wound with carbon fibre resin composite bed 5, described carbon fibre resin composite bed 5 surface is provided with laminated polyester film 6.The size of described body 1 can be carried out customized according to actual requirement size; The bolt hole spacing of described flange 2 meets Standard, is attached thereto without the need to changing the equipment and pipeline that connect.
First the manufacture method of the utility model pipeline section, comprise the steps:, makes the outer core consistent just as inner cavity of pipe geomery, with ensure carbon fiber pipe road shape and size completely the same; Secondly, be wound around mylar at described core outer surface along its axle center hoop, form the inside liner 3 of pipeline, and can simultaneously as releasing agent; After polyester film has been wound around, at its outer surface spraying resin, after resin solidification, forms resin layer 4, and repaired pipe resin layer 4 surface; After finishing, at resin layer 4 outer pipeline axial, hoop is wound around and is longitudinally wound around the carbon fiber being coated with resin, forms the reinforced layer of pipeline to meet requirement of strength, and makes carbon fiber pile up formation flange embryo at the two ends of pipeline; Then, take out core, use mould extruding flange embryo, increase its density and form flange 2, complete the one-body molded of body 1 and flange 2; Body 1 and flange 2 shaping after, at its surface wrap one deck polyester film, and flatten press polish; Finally, require to carry out normal pressures sampling observation experiment to pipeline according to Environmental Conditions, experimental pressure is 1.5 times of working pressure, simultaneously, to batch production often criticize pipeline carry out liner break and pipe explosion sampling observation experiment, experimental pressure is respectively the 4-5 of working pressure doubly, completes the preparation of the present invention for the novel pipeline section of offshore platform seawater lift.
