Abstract
A kind of clean compressed air source unit of LNG pipeline, including：Main leg, the steel plate on main leg, wherein steel plate is equipped with several mounting holes, is equipped with branch pipeline section on mounting hole, flange is equipped at the port of branch pipeline section.The utility model is simple in structure, need to only use a gas bag, just can be cleaned simultaneously to multiple LNG pipelines；The problem for not only solving device resource anxiety substantially increases the clean efficiency of LNG pipeline, moreover, also reducing production cost, accelerates the progress of LNG pipeline modularization construction.
Description
Technical field
The utility model is related to pipeline more particularly to a kind of clean compressed air source units of LNG pipeline.Belong to ocean
Petroleum works field.
Background technology
Currently, the steel constructions pipeline such as liquefied natural gas (LNG), is generally built using modularization.Due to liquefied natural gas pipe
The cleaning amount of wire module is larger, and therefore, LNG pipeline cleaning needs the equipment such as a large amount of drying machine and compressor
LNG pipeline inside is cleaned, thus causes the use of cleaning equipment resource more nervous.And it largely purchases
Or lease these equipment, it will greatly improve the cost that LNG pipeline modularization is built.Moreover, because liquefaction is natural
LNG pipeline modularization construction duration caused by the cleaning of gas pipeline is delayed, and LNG pipeline mould is given
Blockization is built, and huge loss is caused.
Utility model content
The main purpose of the utility model is to overcome disadvantages mentioned above of the existing technology, and it is natural to provide a kind of liquefaction
The clean compressed air source unit of gas pipeline, it is simple in structure, a gas bag need to be only used, it just can be simultaneously to multiple liquefied natural gas pipes
Line is cleaned；The problem for not only solving device resource anxiety substantially increases the clean efficiency of LNG pipeline, and
And production cost is also reduced, accelerate the progress of LNG pipeline modularization construction.
The purpose of this utility model is realized by following technical scheme：
A kind of clean compressed air source unit of LNG pipeline, it is characterised in that：Including：Main leg is mounted on main leg
On steel plate, wherein steel plate is equipped with several mounting holes, is equipped with branch pipeline section on mounting hole, is equipped at the port of branch pipeline section
Flange.
The wall thickness of the main leg is 42 cun.
The wall thickness of the branch pipeline section is 4 cun.
The beneficial effects of the utility model：The utility model is due to the adoption of the above technical scheme, simple in structure, need to only make
With a gas bag, just multiple LNG pipelines can be cleaned simultaneously；Not only solve asking for device resource anxiety
Topic, substantially increases the clean efficiency of LNG pipeline and accelerates liquefied natural gas moreover, also reducing production cost
The progress that pipeline modulesization are built.
Description of the drawings
Fig. 1 is the utility model structure of the main view.
Fig. 2 is the utility model structure schematic side view.
Major Symbol explanation in figure：
1. steel plate, 2. main legs, 3. pipeline sections, 4. first flanges, 5. second flanges.
Specific implementation mode
Such as Fig. 1, shown in Fig. 2, the utility model includes：Main leg 2 is connected by screw bolts mode mounted on main leg's 2
Steel plate 1 in first flange 4, wherein steel plate 1 is equipped with several mounting holes (the present embodiment be four mounting holes), on mounting hole
Branch pipeline section 3 is equipped with using welding or bolt connecting mode, being connected by screw bolts mode at the port of branch pipeline section 3 is equipped with second
Flange 5.
The wall thickness of above-mentioned main leg 2 is 42 cun.
The wall thickness of above-mentioned branch pipeline section 3 is 4 cun.
Above-mentioned steel plate, main leg, branch pipeline section, flange select ordinary carbon steel.
In use, a gas bag will be installed in LNG pipeline one end, then, the utility model is mounted on liquefaction
The other end of natural gas line, after LNG pipeline ventilation, from four 3 exit outlets of branch pipeline section, i.e.,：One gas bag four
A outlet can clean LNG pipeline.
The utility model can select the export volume of branch pipeline section 3 as needed, can also be cleaned simultaneously to multiple pipelines.
The above descriptions are merely preferred embodiments of the present invention, not makees in any form to the utility model
Limitation, it is made by the above technical examples according to the technical essence of the present invention it is any it is simple modification, equivalent variations with
Modification, is still within the scope of the technical solutions of the present invention.
