Description
Technical field
The present invention relates to a kind of installation methods of independent liquid cargo tank commissure insulating layer.
Background technique
Liquefied gas carrier is the specialized ships for the Low Temperature Liquids goods such as conveying liquified oil gas, liquefied natural gas, these liquid goods
It is loaded in the cargo tank of liquefied gas carrier, because the temperature of liquid goods is low, insulating layer to be installed in the outer surface of cargo tank.Liquid
The main purpose of cargo hold insulating layer is that outside heat enters inside cargo tank the evaporation capacity for reducing liquid goods in order to prevent.
For independent liquid cargo tank, laid on its outside plate there are many butt weld, traditional insulating layer mounting process be by
Insulating layer is directly laid on the outside plate of cargo tank and the outer surface of butt weld.It the characteristics of due to liquid goods low temperature, is loading and unloading
Thermal expansion and contraction can occur at the outside plate of cargo tank and butt weld when goods, but since the deformation at butt weld is very bright
Aobvious, the insulating layer being laid in butt weld is easily fallen off, and seriously affects the operation safety of liquid goods.
Summary of the invention
In view of the foregoing drawbacks, the technical problem to be solved in the present invention is to provide a kind of independent liquid cargo tank commissure insulating layers
Installation method guarantees liquid goods operation safety to effectively prevent insulating layer obscission caused by expanding with heat and contract with cold.
The present invention provides a kind of installation method of independent liquid cargo tank commissure insulating layer, set on the outside plate of independent liquid cargo tank
There are multiple weld seams, comprising the following steps:
S1, according to design requirement, make protective cover, the protective cover bottom sets that there are two stabilizer blade, the protective cover bottoms
A recessed portion is formed between two stabilizer blades；
S2, two stabilizer blades are affixed on the outside plate of weld seam two sides using adhesive；
S3, it is arranged and the contour insulating layer of protective cover in the outer surface of outside plate.
Preferably, the insulating layer is sprayed by polyurethane material forms.
Preferably, the protective cover is made of polyurethane material.
Preferably, the polyurethane material density of the protective cover is greater than the polyurethane material density of the insulating layer.
Preferably, the recessed portion is symmetrical about the weld seam.
Preferably, the cross section of the protective cover is in rectangle.
Preferably, the cross section of the recessed portion is in circular arc type.
Preferably, the cup depth of the recessed portion is 50-100mm.
Preferably, the height of the insulating layer is 100-450mm.
Preferably, described adhesive is epoxy glue.
The invention has the beneficial effects that there is cavity, protective cover between the two by the way that recessed portion is arranged in protective cover bottom
Do not contacted directly with weld seam, so as to greatly reduce expanded with heat and contract with cold due to weld seam caused by insulating layer fall off, guarantee liquid goods
Operation safety.

Specific embodiment
Specific embodiments of the present invention will be described in further detail with reference to the accompanying drawing.These embodiments are only used for
Illustrate the present invention, and not limitation of the present invention.
In the description of the present invention, it should be noted that the orientation or position of the instructions such as term " on ", "lower", "inner", "outside"
Setting relationship is to be based on the orientation or positional relationship shown in the drawings, and is merely for convenience of description of the present invention and simplification of the description, rather than
The device or element of indication or suggestion meaning must have a particular orientation, be constructed and operated in a specific orientation, therefore cannot
It is interpreted as limitation of the present invention.
The present invention provides a kind of installation methods of independent liquid cargo tank commissure insulating layer, as shown in Figure 1, mainly applying
At the weld seam 2 on independent liquid cargo tank outside plate 1, comprising the following steps:
S1, according to design requirement, make protective cover 3,3 bottom of protective cover sets that there are two stabilizer blades 32, and 3 bottom of protective cover is two
A recessed portion 31 is formed between a stabilizer blade 32, it is preferable that the cross section of protective cover 3 is in rectangle, and the cross section of recessed portion 31 is in circle
Camber, and it is symmetrical about weld seam 2, the cup depth h2 of recessed portion 31 is 50-100mm, guarantees that protective cover 3 in the next steps may be used
With the enough distances in interval between weld seam 2.
S2, as shown in Fig. 2, two stabilizer blades 32 are affixed to using adhesive 4 on the outside plate 1 of 2 two sides of weld seam, it is preferable that
The distance between stabilizer blade 32 and weld seam 2 L be 100-200mm, adhesive 4 be epoxy glue, thickness h 1 be 5-15mm, stabilizer blade 32 with
The stickup width L1 of outside plate 1 is 10-50mm.
S3, as shown in figure 3, outside plate 1 outer surface setting with the contour insulating layer 5 of protective cover 3, such as using spraying side
Insulating layer 5 is arranged in formula, and wherein the height h of protective cover 3 and the height H of insulating layer 5 are identical, is 100-450mm.
Preferably, protective cover 3 and insulating layer 5 all use polyurethane material, and the polyurethane material density of protective cover 3 is greater than
The polyurethane material density of insulating layer 5 reduces influence of the recessed portion 31 to thermal insulation property, reaches better heat insulation effect.
In conclusion the invention has the beneficial effects that, by the way that recessed portion is arranged in protective cover bottom, there is sky between the two
Chamber, protective cover do not contact directly with weld seam, so as to greatly reduce expanded with heat and contract with cold due to weld seam caused by insulating layer fall off,
Guarantee liquid goods operation safety.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and replacement can also be made, these are improved and replacement
Also it should be regarded as protection scope of the present invention.
