Puzzlement tradition pipe-line etching problem (including internal corrosion and outer corrosion), the most also good thermo-insulation properties can be overcome
Novel Land petroleum delivery combined tube.
Background technology
The tubing of oil pipeline is typically steel pipe, and in the oil gas in oil pipeline rich in element sulphur and acidic materials
And the soil environment of work so that steel oil pipeline easily corrodes, and in turn results in various oil and gas leakage thing
Therefore.In Canada, rupturing of the oil and gas pipes of 56% is caused by corrosion, and in the U.S., the oil pipeline of 31.97% and
Rupturing of the gas pipeline of 18.75% is caused by corrosion.The economic impact report corroded about Usa Metals according to portion is aobvious
Showing, the economic loss caused because of corrosion every year reaches 300,000,000,000 dollars, has accounted for the 1% of this petroleum pipeline Industrial Output.
In addition to directly affecting economy, rupturing of petroleum pipeline can directly result in the environment that oil gas flows to the external world,
And then cause blast, fire, people and animals' injures and deaths and environmental pollution.As a example by the U.S., from 1994 to 2013 years, have 745
Playing serious oil and gas leakage accident, cause 363 people dead, 1059 people are injured.Additionally, China also fails to escape by luck in this respect.Its
In, the Qingdao oil pipeline explosion accident impact with generation in 2013 is the most far-reaching.In this explodes, 62 people are dead, 136 people
Injured, direct economic loss reaches 7.5172 hundred million yuan.
Current domestic newly-built transportation pipe, owing to being limited by steel strength used, discharge pressure is the highest, conveying effect
Rate is low, and intermediate booster pump station is many, and investment is big.The discharge pressure of pipeline is 3.9～4.6MPa in early days, in recent years great majority pipe
Line the most only only increases to 6.4MPa, and the distance between pumping plant is about 60km.And developed country's feed-line pressure is up to 8～12MPa,
Pumping plant spacing 80～100km, the overall economic efficiency index such as transfer efficiency, steel using amount, pumping plant investment is significantly better than domestic.Aobvious
So, the intensity of constantly improve pipe line steel and discharge pressure, be the development trend of transportation pipe.For adapting to this trend, X110
Level and X120 level steel have been succeeded in developing.But, the relation the longest due to the strength and toughness of steel and high-pressure delivery pair
The requirement of steel fracture toughness, current developed country, such as Japan, Europe, North America batch production are also formally come into operation
Hi-grade steel is only X80 level high-grade steel, and wherein China's the second west to east gas pipeline project is the X80 that the whole world is largest.As for X80
Above steel, not yet reach related request, the most not yet large scale investment at present to concrete petroleum pipeline due to fracture toughness
In application.
Obviously, the pipe-line requirement to strength and toughness, surmount the limit of modern metallurgical technology.For understanding
Certainly this problem, foreign study glass reinforced plastic pipe (Glassfibre reinforced polymer pipe, GFRP pipe).
Compare with traditional steel pipe, although this pipeline has corrosion resistance and good, matter ratio low (quality is little and intensity is high) by force, water
Profit condition good (inner wall smooth, conveying capacity are strong), the advantage such as maintenance cost.But, due to glass fibre, to have tensile strength strong
And the feature that comprcssive strength is low, easily there is inside flexing in this pipeline under vacuum or negative pressure state, at the work of upper strata soil pressure
With lower and then destroy.
Additionally, foreign study composite reinforced pipe (Composite Reinforced Line Pipes, CRLP),
I.e. steel/glass fiber reinforced plastic pipe, it both make use of the intensity of steel, had played again glass fibre advantage in terms of crack arrest.Steel/glass
Glass fiber composite pipe can reduce the material cost of pipeline engineering, mounting cost and welding cost etc., is further substituted traditional painting
Layer.Compare above-mentioned glass reinforced plastic pipe, the buckling problem under vacuum or negative pressure state, or solve；But, perplex conventional steel
The etching problem of pipe still exists.
