Abstract
The present invention provides a kind of insulating layer installation method of independent liquid cargo tank commissure, the outside plate of independent liquid cargo tank is equipped with multiple weld seams, comprising the following steps: S1, according to design requirement uses retractable material to make protective cover；S2, protective cover is affixed on weld seam and the outside plate of weld seam two sides using adhesive；S3, insulating layer is set in the outer surface of outside plate and protective cover.The invention has the beneficial effects that the protective cover made of retractable material has enough retractilities, it can be effectively prevented insulating layer obscission caused by expanding with heat and contract with cold, guarantee the operation safety of liquid goods.
Description
Technical field
The present invention relates to a kind of insulating layer installation methods of independent liquid cargo tank commissure.
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 brighter
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 insulating layers of independent liquid cargo tank commissure
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 insulating layer installation method of independent liquid cargo tank commissure, set on the outside plate of independent liquid cargo tank
There are multiple weld seams, comprising the following steps:
S1, according to design requirement, use retractable material to make protective cover；
S2, protective cover is affixed on weld seam and the outside plate of weld seam two sides using adhesive；
S3, insulating layer is set in the outer surface of outside plate and protective cover.
Preferably, the protective cover uses glass wool material.
Preferably, the outer surface of the protective cover is in circular arc type.
Preferably, the protective cover of the weld top with a thickness of 50-100mm.
Preferably, the stickup width of the protective cover and the outside plate of weld seam side is 100-200mm.
Preferably, described adhesive is epoxy glue.
Preferably, the insulating layer is sprayed by polyurethane material forms.
Preferably, the insulating layer with a thickness of 100-450mm.
The invention has the beneficial effects that the protective cover made of retractable material has enough retractilities, Ke Yiyou
Insulating layer obscission caused by expanding with heat and contract with cold is prevented to effect, guarantees the operation safety of liquid goods.

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 insulating layer installation methods of independent liquid cargo tank commissure, 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, as shown in Figure 1, according to design requirement, make protective cover 3 using retractable material, protective cover 3 preferably uses
The good glass wool material of telescopicing performance, and outer surface is in circular arc type.
S2, protective cover 3 is affixed to using adhesive 4 on the outside plate 1 of 2 two sides of weld seam 2 and weld seam, adhesive 4 is preferably
Epoxy glue is selected, thickness h 1 is 5-15mm.In addition, the stickup width L of protective cover 3 and the outside plate 1 of 2 side of weld seam is 100-
The thickness h of 200mm, the protective cover 3 at 2 top of weld seam are 50-100mm.
S3, as shown in Fig. 2, insulating layer 5 is arranged in the outer surface of outside plate 1 and protective cover 3.Preferably, insulating layer 5 is by poly- ammonia
Ester material sprays to be formed, and thickness H is 100-450mm, to effectively carry out low temperature environment to the liquid goods in cargo containment system
Protection.
In conclusion the invention has the beneficial effects that, the protective cover made of retractable material has enough flexible
Property, it can be effectively prevented insulating layer obscission caused by expanding with heat and contract with cold, guarantee the operation safety of liquid goods.
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.
