Description
Technical field
It is that a kind of intensity is higher the present invention relates to a kind of utilidor, toughness preferably, and has preferable sealing thermal insulation function
Pipeline.
Background technology
In pipeline and various pipeline transportation industries on natural gas carrier vessel of new generation, LNG pipeline surface
All it is coated with different materials and can ensure that the heat-insulation layer of sealing, these heat-insulation layers serves insulation and sealing function, can be to prevent
Only fluid seepage.
, it is necessary to pay PU bubbles in advance with glass web when carrying out heat-insulation layer making to the LNG pipeline surface on ship in the past
Foam is wrapped on pipeline, overall by injecting formation of foam in gap, fiberglass is then covered in outer surface, then surface is polished
It is smooth attractive in appearance to ensure.
But the utilidor being so made has the disadvantage that：
1st, the making of tube surfaces heat-insulation layer due to needing to install, the process such as polish, make, waste time and energy, cause to build week
Phase is long, and consumption is artificial more.
2nd, needed after PU has foamed to being polished at its surface irregularity, great waste is caused to raw material.
3rd, traditional FRP heat-insulation systems are due to without pliability, therefore shunk when different in pipeline contract on cooling, therefore pipe
Road surface has certain gap with insulating barrier, if inside has follow-up icing, will caused in a big way even
The destruction of whole system.
4th, traditional glass steel covers the heat-insulation system on surface, because glass hardness of steel is poor, does not possess pliability flexibility, by
It is perishable to external force, cause heat-insulation system to be easily destroyed.
5th, when the fiberglass in the poor fire of conventional utilidor, pipeline is heated, temperature can pass through fiberglass, so that broken
PU foams inside bad, cause peril.
The content of the invention
It is an object of the invention to overcome above-mentioned deficiency there is provided a kind of high tenacity fire-retardant heat insulation pipeline and its installation method,
It is not only easy to make for this pipeline, it is to avoid the waste of raw material, while pliability is good, intensity is high, fire resistance is good, seamless
Gap, good sealing effect improves the heat insulation effect of pipeline.
The object of the present invention is achieved like this：
A kind of high tenacity fire-retardant heat insulation pipeline, it includes pipeline body, the multiple support rings of external stability of pipeline body, phase
Polyureas coat is wrapped up between the periphery of adjacent two support rings, foam is filled between polyureas coat and pipeline body.
The polyureas coat includes stainless steel cloth, by the online spray polyurea layer of stainless steel wire, making stainless steel cloth
It is coated in polyurea layer and forms completely, the top surface of the polyurea layer is shiny surface, and the bottom of polyurea layer is mat surface.
The both sides of the polyureas coat are fixed in support ring, and the outer seam of adjacent two pieces of polyureas is coated with stainless steel
Silk screen, and bonded two pieces of polyureas coats by polyureas.
The head and the tail of the polyureas coat are engaged by clamping, and on the same line, this is always for the clamping position of all polyureas coats
Covered with stainless steel cloth on line, stainless steel wire is coated with polyureas on the net.
The polyureas coat is while cut protuberance, and the another side of polyureas coat cuts breach, the protuberance of polyureas coat
Head and the tail are completed after in embedded breach to be engaged by clamping.
The support ring is made up of three-decker, wherein while being glass fibre, centre is foam, and another side is polyureas
Layer, is fixed between the support ring and pipeline body by foam.
High-density foam is installed at the pipeline body conduit saddle position, and in piece of surface covering glass steel.
A kind of the step of installation method of high tenacity fire-retardant heat insulation pipeline is：
First, all support rings first on prefabricated pipeline；
2nd, prefabricated polyureas coat；
3rd, in-site installation is removed with prefabricated support ring and polyureas coat, support ring is fixed on pipeline outer wall；
4th, polyureas coat is fixed in support ring, then the head and the tail of polyureas coat is engaged by clamping, and by polyureas coat
Both sides are fixed in support ring；
5th, the clamping position of all polyureas coats on the same line, covers a stainless steel on this straight line
Silk screen, then in the online spray polyurea of stainless steel wire；
6th, in the bottom of each polyureas coat and top holes drilled through, the injection of foam is carried out by the hole of bottom；
7th, the drill hole of each polyureas coat is blocked；
8th, seam coats stainless steel cloth outside adjacent two pieces of polyureas, and in the online spray polyurea of stainless steel wire,
Bond adjacent polyureas coat；
9th, to seam polishing fairing outside polyureas, the installation of utilidor is completed.
In step one to addition Pipe installing step between step 9：Before the installation of pipeline the elbow of prefabricated pipeline and
Not-go-end, in-site installation is removed with prefabricated elbow and not-go-end, by elbow and not-go-end set on the relevant position of pipeline,
The bottom and top holes drilled through of elbow and not-go-end, and foam is injected from bottom, then drill hole is blocked, finally to elbow and only
Surface polishing, the spray painting at end.
Installation steps are added in step 3：High-density foam is installed at conduit saddle position, and in piece of surface covering glass steel.
Compared with prior art, the beneficial effects of the invention are as follows：
This high tenacity fire-retardant heat insulation pipeline has coated a strata urea coat in pipe surface, and polyureas coat is polyurea coating
Stainless steel cloth is formed, and compared with original fiberglass, it has advantages below：
1st, the pliability of polyureas coat is good, collapsible, can prevent hull from rocking, pipeline shrink and it is damaged.
2nd, the intensity of polyureas coat is high, wants high 10 times compared with original glass hardness of steel, its is not easily damaged.
3rd, the good flame resistance of polyureas coat, after polyureas surface carbonation, because stainless steel cloth is combined with polyureas, surface is not
It can peel off, can prevent the PU foams of inside from further burning, reach more preferable flame retardant effect.
4th, pipeline outer wall is coated with foam, and pipeline can, gapless integrated with foam so that the good airproof performance of pipeline,
Heat insulation effect is good.
5th, polyureas coat and elbow, not-go-end can be prefabricated, cost-effective, convenient to install, and improve pipe insulating layer
Installation effectiveness.
