Description
Technical field
The present invention relates to pipe technology field, more particularly to a kind of multiple tube and its manufacture and installation method.
Background technology
Flexible composite pipe has that joint is few, and laying is convenient, and connection is quick reliable, and it is excellent to save construction manpower and installation period etc.
Point, oil and gas pipeline industry is widely used to, particularly requires high seabed oil-gas pipeline.Although flexible composite pipe
Easy for installation, still, it is generally desirable to tubing when in use has certain rigidity, can bear inside and outside high pressure, is unlikely to produce
The failure behaviours such as conquassation, flexing.
Or existing technology is exactly rigid pipe before laying, supplied in the form of straight tube, per root long degree between 6-12m,
Erection joint is more, and reliability is low；Flexible pipe in a pre-installation, coil supply, according to diameter difference 200-1000m it
Between, successively, non junction is easy for installation, and reliability is high, but its natural flexibility, ring stiffness are equally inherited during use
It is relatively low, the failure behaviours such as conquassation, flexing easily occur.
Chinese patent CN20316239 U disclose a kind of hard and soft composite bushing, including rigid conduit, it is characterised in that
In rigid conduit joint location, the connection of flexible compound inner liner is set.Flexible compound inner liner uses neoprene flexible sleeve.
The patent combines the advantage of two kinds of rigid conduit and flexible duct, and using hard and soft pipeline synergy, ring stiffness is high, still
This pipeline contains rigid pipe, same installation difficulty.
The content of the invention
The primary and foremost purpose of the present invention is to provide the multiple tube that a kind of ring stiffness is high, is easy to coil, facilitate installation.
To achieve these goals, the present invention is taken including following technical scheme：
A kind of multiple tube, the multiple tube include layers of reinforcement, and layers of reinforcement thickness is 0.15mm~20mm, and internal diameter of the pipeline is
20mm~250mm, fibre-reinforced prepregs are included in layers of reinforcement.
Multiple tube provided by the invention, by weight percentage, the fibre-reinforced prepregs include resin and strengthening material
Material：
The parts by weight of parts by weight of resin 3~5
The parts by weight of parts by weight of reinforcing material 5~7.
Wherein, one or more of mixtures of the resin in epoxy resin, phenolic resin or unsaturated polyester (UP).
Wherein, the reinforcing material is selected from carbon fiber, glass fibre, aramid fiber, polyester fiber, polyethylene fibre, steel
One or more of mixtures in silk or steel band.
A kind of multiple tube, in addition to containing above-mentioned layers of reinforcement, also containing inner liner and/or external protection, inner liner
Thickness be 0.15mm~20mm, the thickness of external protection is 20mm~250mm.Inner liner and external protection are selected from polyethylene
(PE), nylon (PA), polyvinylidene fluoride (PVDF), polyphenylene sulfide (PPS), polyether-ether-ketone (PEEK), PEKK (PEKK)
Or one or more of mixtures in polyethylene foamed.Inner liner can prevent intermediate layer from directly being contacted with internal flow, outside
Protective layer can prevent the direct sunlight of outside, add above-mentioned inner liner in multiple tube and external protection can be protected preferably
The object transported in multiple tube.The inner liner and external protection are as known to the method for raw material manufacture finished product has been the public.
It is another object of the present invention to provide a kind of method for installing above-mentioned multiple tube, in order to realize the purpose, take
Technical scheme it is as follows.
A kind of method for installing multiple tube provided by the invention comprises the following steps：
(1) by the multiple tube coiled lay enter construction location, can bending as requested, cut-through；
(2) multiple tube is connected into joint and fixed good position, the position of directly fixed multiple tube if without joint；
(3) fibre-reinforced prepregs in multiple tube are solidified.
Solidification in the present invention includes be heating and curing technique, infrared curing process and microwave curing process, can individually make
With or be used together.
Be heating and curing technique：The flowing water greater than or equal to 20 DEG C is passed through to pipeline.In flowing water temperature range, water temperature is used
Higher, hardening time is shorter, and installation effectiveness is higher.
Infrared curing process:The use of wavelength is 0.75nm~106Nm infrared heater heating pipe.In infrared wavelength
In the range of, multiple tube enhancement layer thickness is bigger, shorter using IR wavelength, and heat penetration is deeper, and the effect that is heating and curing is better；
Multiple tube enhancement layer thickness is smaller, longer using IR wavelength, and heating is faster, and hardening time is shorter, and installation effectiveness is higher.
Microwave curing process：Launch 900 MHZ~2450MHZ microwave into pipeline using microwave generator.
In microwave range：The size of multiple tube is bigger, depth is deeper, using microwave frequency more high solidification effect more
It is good；The size of multiple tube is smaller, depth is more shallow, and the lower solidification effect of frequency of the microwave used is better.
It is still another object of the present invention to provide the manufacture method of above-mentioned multiple tube, without inner liner and/or external protection
Multiple tube, manufacture method includes：Using wrapping machine, ring winds fibre-reinforced prepregs on core cylinder.Except layers of reinforcement
In addition, the multiple tube also comprising inner liner and/or external protection, manufacture method include：Use wrapping machine, on inner liner, ring
To winding fabric thermoplasticity prepreg, and/or external protection is coated to fabric thermoplastic prepreg.
Fibre-reinforced prepregs in the multiple tube of above-mentioned manufacture are uncured, carry out curing operation again during installation.
The scope of ring stiffness after the multiple tube installation of the present invention is 40 KN/m2~7504 KN/m2。
The invention has the advantages that：
(1) because the multiple tube in the present invention contains layers of reinforcement, fiber reinforcement during installation to containing in layers of reinforcement
Prepreg, which carries out solidification, can make multiple tube ring stiffness is greatly improved after mounting.
(2) due to not solidifying before the multiple tube installation in the present invention, so it has the spy for being equally easy to coil with flexible pipe
Point, so joint is few, it is easy for installation.
