Description

Pipeline bracket with adjustable LNG cryrogenic heat preservation height

Technical Field

The utility model belongs to the energy transportation field especially relates to a pipeline bracket with adjustable LNG cryrogenic heat preservation height.

Background

The three major disposable energy sources in China are petroleum, natural gas and coal. And natural gas can be discharged to the second in the world. In recent years, China has suffered serious loss in domestic petroleum production areas due to petroleum crisis. And meanwhile, the natural strong force is adopted, so that the environment is seriously polluted. This has made liquefied natural gas an environmentally friendly and clean fuel type fuel available.

Liquefied Natural Gas (LNG) is the most clean fossil energy on earth, and the main component of LNG is methane. The liquefied natural gas is colorless, tasteless, nontoxic and noncorrosive, the volume of the liquefied natural gas is about 1/625 of the volume of the same amount of gaseous natural gas, and the mass of the liquefied natural gas is only about 45 percent of the same volume of water.

The manufacturing process comprises purifying natural gas produced in a gas field, liquefying at a series of ultralow temperatures, and transporting by a liquefied natural gas carrier. After the liquefied natural gas is combusted, the pollution to the air is very small, and the heat emitted by the liquefied natural gas is large, so the liquefied natural gas is a relatively advanced energy source.

The liquefied natural gas is liquid after the natural gas is compressed and cooled to the boiling point temperature, and the liquefied natural gas is usually stored in a low-temperature storage tank at-161.5 ℃ and about 0.1 MPa. The main component of the methane is methane, and the methane is transported by a special ship or an oil tank truck and is gasified again when in use. Since the 70 s of the 20 th century, the world production and trade volume of liquefied natural gas has increased rapidly, and in 2005, the international trade volume of LNG reaches 1888.1 billion cubic meters, the largest export country is indonesia, and the export 314.6 billion cubic meters; the largest importing country is 763.2 billion cubic meters in japan.

With the increasing demand of the nation on energy, the development of the LNG industry plays an important role in optimizing the energy structure of China, effectively solving the double problems of energy supply safety and ecological environment protection and realizing the sustainable development of economy and society. LNG can be transported in a variety of ways, of which pipeline transport is one of the most important. Particularly, the transportation pipeline is generally long, the number of the supporting structures of the oil and gas pipeline is large, and the requirements on safety, cost, stability and service life are high.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to disclose a LNG cryrogenic keeps warm adjustable pipeline bracket of height that simple to use, production safety, cold insulation can be good, highly can regulate and control.

The purpose of the utility model is realized like this:

an LNG cryogenic heat-preservation height-adjustable pipeline support comprises a cold-preservation structure 2, a pipe hoop 1, a fastener 3, a support plate 4 and a barb type base; the cold insulation structure 2 is positioned in the pipe hoop 1, the fastening piece 3 is connected with the pipe hoop 1, the support plate 4 is fixed on the pipe hoop 1, the support plate 4 is connected with the barb type base through a bolt, and the barb type base comprises a support bracket 5, a flat plate 6 and barbs 7; the support bracket 5 is provided with a bolt hole, the support bracket 5 is fixed on the upper surface of the flat plate 6, and the barb 7 is fixed on the lower surface of the flat plate 6.

Further, the cold insulation structure 2 is one or a combination of several of an anti-rust layer, a cold insulation layer, a moisture-proof layer, a protective layer, a moisture-proof layer and an identification layer.

Further, the support plate 4 is provided with bolt holes.

Further, the number of the support plates 4 is one or more.

Further, the number of barbs 7 of the barb-type base is one or more.

Further, the size and position of the bolt holes on the support plate 4 correspond to the size and position of the bolt holes on the support brackets 5 of the barb-type base.

The utility model has the advantages that:

the utility model discloses simple to use, production safety, cold insulation can be good and highly can regulate and control, in LNG pipeline construction, both can improve the efficiency of construction, can control the process again, and the emergence of quality accident is avoided to the at utmost, has positive effect and important to the development of LNG project.

Detailed Description

The invention is further described below with reference to the accompanying drawings:

as shown in fig. 1, 2 and 3, the LNG cryogenic insulation height-adjustable pipeline bracket comprises a cold insulation structure 2, a pipe hoop 1, a fastener 3, a support plate 4 and a barb type base; cold insulation structure 2 is located ferrule 1, and fastener 3 is connected with ferrule 1, and backup pad 4 is fixed on ferrule 1, and backup pad 4 and barb formula base pass through bolted connection.

Further, the support plate 4 is provided with bolt holes.

Further, the number of the support plates 4 is one or more.

Further, the barb type base comprises a support bracket 5, a flat plate 6 and a barb 7; the support bracket 5 is provided with a bolt hole, the support bracket 5 is fixed on the upper surface of the flat plate 6, and the barb 7 is fixed on the lower surface of the flat plate 6.

Further, the number of barbs 7 of the barb-type base is one or more.

When the barb type pipeline support is used, (1) the barb type pipeline support base is placed at a set position, and the barb part is driven into the ground to maintain the stability of the upper structure.

(2) And selecting a bolt hole position with a proper height on the support plate according to the height of the pipeline, and fixing the lower support structure of the support and the base through the bolt hole.
