Abstract
The utility model relates to a kind of heat insulation layer structure of LNG pipeline, it is characterized in that: this heat insulation layer structure is arranged on the outer wall of body (1), this heat insulation layer structure comprises a circle and is arranged on the outside polyurea layer (2) of body (1), the inside of described polyurea layer (2) is provided with steel wire (3), multiple PU foam strip (4) is provided with between the outer wall of described steel wire (3) and body (1), this PU foam strip (4) is divided into polylith region by between body (1) and steel wire (3), PU foam (5) is filled with in region between adjacent two pieces of PU foam strips (4).The heat insulation layer structure of this LNG pipeline is not only easy to make, improves make efficiency, avoids the waste of raw material simultaneously, it also avoid gap on pipeline, improves the heat insulation effect of pipeline.
Description
Technical field
The utility model relates to a kind of heat insulation layer structure, and it, for surface in LNG pipeline, plays insulation effect to the LNG Liquefied natural gas in pipeline.
Background technique
LNG(Liquefied Natural Gas) ship is the specialized ships of transport liquefied gases under subzero 163 degrees Celsius of low temperature, being high technology, highly difficult, high added value " three is high " product, is a kind of " marine super van cooler ".In this natural gas carrier vessel of new generation, liquefied natural gas (LNG) tank and pipeline are by different materials and can guarantee that the thermal insulation layer of sealing forms.Wherein thermal insulation layer serves insulation and prevents the effect of fluid seepage.
When thermal insulation layer making being carried out to tube surface in the past, need first a pipe first to be cut, make two semi-circular tubes, take subsequently on another set of product line and spray PU on the outer wall of semi-circular tube, and foaming forms one layer of heat preservation layer, again with to its surface finish with ensure surface smooth attractive in appearance, the semi-circular tube finally two being coated with PU foam layer welds formation thermal insulation pipe.
But the pipe made like this has three place's shortcomings:
1, body spraying needs to shift repeatedly on a production line, wastes time and energy, causes spray efficiency to reduce.
2, PU needs after having foamed to cut its surface irregularity place, and the PU foam material that these cut down is more more, causes great waste to raw material.
3, after two semi-circular tubes weld after having sprayed, weld has obvious macroscopic gap, and weld does not have PU layer, causes the heat insulation effect at gap place poor.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of heat insulation layer structure of LNG pipeline, and it is not only easy to make, improve make efficiency, avoid the waste of raw material simultaneously, it also avoid gap on pipeline, improve the heat insulation effect of pipeline.
The purpose of this utility model is achieved in that
The heat insulation layer structure of the utility model LNG pipeline, it is characterized in that: this heat insulation layer structure is arranged on the outer wall of body, this heat insulation layer structure comprises the polyurea layer that a circle is arranged on body outside, the inside of described polyurea layer is provided with steel wire, multiple PU foam strip is provided with between described steel wire and the outer wall of body, this PU foam strip will be divided into polylith region between body and steel wire, be filled with PU foam in the region between adjacent two pieces of PU foam strips.
Compared with prior art, the beneficial effects of the utility model are:
The heat insulation layer structure of this LNG pipeline is by producing a heat insulation layer structure in advance, subsequently this heat insulation layer structure is directly coated to the outer wall of pipe, when two pipelines need to splice, by the tube welding of two sections of tube interiors, and the PU foam outside pipe is fixed up just completes the splicing of pipeline, and without the need to pipe being divided into two semi-circular tubes spraying treatmen respectively, thus avoid the appearance in gap on pipe, and save raw material, improve make efficiency.
Accompanying drawing explanation
Fig. 1 is the sectional view of the heat insulation layer structure of the utility model LNG pipeline.
Fig. 2 is the sectional view after the heat insulation layer structure of the utility model LNG pipeline launches.
Wherein: body 1, polyurea layer 2, steel wire 3, PU foam strip 4, PU foam 5.
Embodiment
See Fig. 1, the utility model relates to a kind of heat insulation layer structure of LNG pipeline, this heat insulation layer structure is arranged on the outer wall of body 1, this heat insulation layer structure comprises the polyurea layer 2 that a circle is arranged on body 1 outside, the inside of described polyurea layer 2 is provided with steel wire 3, be provided with multiple PU foam strip 4 between described steel wire 3 and the outer wall of body 1, this PU foam strip 4 is divided into polylith region by between body 1 and steel wire 3, is filled with PU foam 5 in the region between adjacent two pieces of PU foam strips 4.
As Fig. 2, when the heat insulation layer structure of this LNG pipeline makes, first spray the polyurea layer of one deck strip, subsequently at the outside Cladding Steel silk screen of polyurea layer, subsequently according to the thickness that thermal insulation layer needs, at the PU foam strip of the inner side of polyurea layer spraying corresponding height, then heat insulation layer structure is now coated on the outer wall of a segment pipe, the two ends of polyurea layer overlap and are fixed up, fill out PU foam in gap between the most backward adjacent two PU foam strips, the thermal insulation layer just completing a segment pipe makes.
When two pipelines need to splice, by the tube welding of two sections of tube interiors, and the PU foam outside pipe is fixed up just completes the splicing of pipeline, and without the need to pipe being divided into two semi-circular tubes spraying treatmen respectively, thus avoid the appearance in gap on pipe, and save raw material, improve make efficiency.
