Description
Technical field
The present invention relates to sea water pipe, more particularly to a kind of manufacture for the new pipeline section of offshore platform seawater lift
Method.
Background technology
With developing by leaps and bounds for offshore oil, drilling and production platform quantity are continuously increased, and platform is set using seawater cooling
Standby, so platform is provided with sea water pump, sea water pump works positioned at b.s.l., by sea water pipe by seawater lift to deck
More than.Sea water pipe is made up of some pipeline sections, can not only convey seawater, additionally it is possible to bear the weight and seawater of bottom sea water pump
Vibration when pump is operated.Sea water pipe is manufactured using metal material, and long-term work causes serious corrosion in briny environment,
And it is attached with marine growth, it has to regularly replace.Platform is once attempted to use alloy pipeline in recent years, but still there is corruption
Erosion problem, using the costly of Langaloy pipeline, platform is difficult to bear；Also once attempted to use carbon fiber or glass reinforced plastic pipe
Line, but existing carbon fiber and GRP pipe use bonding form with flange connection, it is impossible to meeting seawater lift pump work will
Ask.Therefore in the urgent need to being improved to seawater lift pipeline, to reach the effect of corrosion-resistant and low maintenance cost.
The content of the invention
The purpose of the present invention is to overcome of the prior art not enough there is provided one kind is safe and reliable, and intensity is high, seawater corrosion resistance
The new pipeline section for offshore platform seawater lift manufacture method.
In order to solve the above-mentioned technical problem, the present invention provides a kind of for the new pipeline section of offshore platform seawater lift
Manufacture method, the pipeline section includes body and is arranged on the flange at body two ends, and the body and flange are structure as a whole composition,
The body and flange include：The inner liner being made up of mylar, the surface spraying of the inner liner has resin bed, the spray
The inner liner outer pipeline for scribbling resin bed axially and longitudinally, is wound with carbon fibre resin composite bed, and the carbon fibre resin is answered
Close layer surface and be provided with laminated polyester film；Its manufacture method specifically includes following steps：
(1) make outer just as the consistent core of inner cavity of pipe geomery；
(2) the core outer surface winds mylar along its axle center ring, forms the inner liner of pipeline；
(3) in the mylar trypsin method resin, after after resin solidification, pipe resin layer surface is repaired；
(4) after the finishing of pipe resin layer surface, the pipeline axial direction in polyester film outer, ring is wound and longitudinally wound spraying
There is the carbon fiber of resin, form the enhancement layer of pipeline, and make carbon fiber accumulate to form flange base at the two ends of pipeline；
(5) core is taken out, using the flange base in mould pressing steps (4), increases its density formation flange, completes body
With being integrally formed for flange；
(6) after body and flange forming, in its strata ester film of surface wrap one, and press polish is flattened；
(7) normal pressures sampling observation experiment, liner rupture and pipe explosion sampling observation are carried out to the pipeline section after shaping to test, and are completed
Preparation for offshore platform seawater lift pipeline section.
The beneficial effects of the invention are as follows：
1st, the present invention is integrally formed using body and flange, seawater conveying is not only met, while meeting seawater lift pump work
Make, lift the reliability of sea water pipe；
2nd, the present invention uses carbon fibre material, and lightweight, cost is low, easy for installation, with higher tensile strength and
Flexural strength, and seawater corrosion resistance, pipeline are difficult to adhere to marine growth.

Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As shown in accompanying drawing 1 to 3, a kind of new pipeline section for offshore platform seawater lift, including body 1 and setting
Flange 2 at the two ends of body 1, the body 1 and flange 2 are structure as a whole composition；The body 1 and flange 2 are carbon fiber one
It is secondary Wrapping formed, and binding resin solidify to form；The body 1 and flange 2 include：The inner liner 3 being made up of mylar, institute
Stating the surface spraying of inner liner 3 has resin bed 4, and the outer pipeline of inner liner 3 for being coated with resin bed 4 axially and longitudinally, is twined
Carbon fibre resin composite bed 5 is wound with, the surface of carbon fibre resin composite bed 5 is provided with laminated polyester film 6.The body 1
Size can carry out customized according to actual requirement size；The bolt pitch of holes of the flange 2 meets Standard, without change with
The equipment being connected and pipeline.
The manufacture method of pipeline section of the present invention, comprises the steps：First, make outer just as inner cavity of pipe geomery phase one
The core of cause, to ensure that carbon fiber pipe road shape and size are completely the same；Secondly, in the core outer surface along its axle center ring
Mylar is wound, the inner liner 3 of pipeline is formed, and releasing agent can be used as simultaneously；After the completion for the treatment of that polyester film is wound, outside it
Surface spraying resin, after formation resin bed 4 after resin solidification, and repairs 4 surface of pipe resin layer；After finishing is finished, in resin
The outer pipeline axial direction of layer 4, ring is wound and longitudinally wound the carbon fiber for being coated with resin, and it is strong to meet to form the enhancement layer of pipeline
Degree is required, and makes carbon fiber accumulate to form flange base at the two ends of pipeline；Then, core is taken out, flange base is extruded using mould,
Increase its density formation flange 2, complete being integrally formed for body 1 and flange 2；After body 1 and flange 2 are molded, twined on its surface
Around a strata ester film, and flatten press polish；Finally, normal pressures sampling observation is carried out to pipeline according to use environment requirement to test, it is real
