insulation paper

The ordinary cryogenic insulation paper(incompatibility with oxygen):

Ordinary cryogenic insulation paper is made of a special process with high quality chemical fiber, usually compositely used with aluminum foil or single (double)aluminized polyester film. It is used in the storage container of cryogenic liquid(liquid helium, liquid nitrogen and liquid argon) and also used in dry ice storage vessels. Its advantage are lightweight, good uniformity, low thermal conductivity, large thermal contact resistance, low outgassing rate in vacuum. This product can be applied in a wide temperature range:-269°C-190°C.

Q:How much water can a cubic gas burn? emergency
A cubic meter of natural gas is about 8600 calories, generally speaking, a liter of water per degree of heat required to increase the temperature of the card is 1000
Q:Natural gas pipeline is how to connect the seal
The utility model is connected through a flange and is fixed by bolts, and the middle part is provided with a cushion, a graphite winding or a metal winding
Q:I would like to ask the working principle of gas stove timer
The timer can be turned off by pressing the upper adjusting key and the lower adjusting key at the same time. (6) each time the key, blue backlight timer will automatically turn on the light, light up as a case operation timer automatically shut down the blue backlight source after 10 seconds (7) according to the needs of customers can choose to use and not to use the cooker with timing function, discomfort the timing function will not function as the influence range state (combustion); application timing function, the only stove solenoid valve control, the controller will in time countdown the final 10 seconds automatically closes the electromagnetic valve, cut off the input range air, and not have to multiple focal eye burning independently timing control function.
Q:0.3T gas steam boiler about one hour to burn a lot of natural gas
0.3 tons equivalent to: 0.3 tons x 0.7 MW / ton =0.21 megawatts of power, equivalent to 210 billion joules per second heat. So the heat consumed in an hour is 756 mj. Natural gas in accordance with the parameters provided by users 32 MJ / cubic meter, then the boiler needs: 756/32=23.625 cubic meters per hour. If the boiler efficiency is considered, this figure may be even larger, may reach 28 cubic meters per hour.
Q:What are the classification of natural gas
According to the classification of natural gas can be divided into: gas, non hydrocarbon gas;According to the content of acid gas, it can be divided into: net gas and acid gasOur habits: associated gas, gas reservoir and gas condensate gas
Q:What pipe used in indoor natural gas pipeline
As long as 4843km of the west east gas pipeline line using 1219mm diameter of X80 steel pipeline steel, the gas pressure increased to 12Mpa. Generally speaking, X80 steel is ferrite and bainite dual phase structure, X100 pipeline steel is bainite structure, X120 pipeline steel for ultra low carbon bainite and martensite. For the pipeline of natural gas pipeline, strength, toughness and weldability are three basic quality control indexes
Q:When you find the home gas leak, you will immediately take the solution is
A, combustible gas and oxygen or air mixed with open fire prone to explosion, open the exhaust fan will produce electric spark, ignite mixed gas, there is the risk of explosion, so B error
Q:Why can't a gas stove use natural gas?
Natural gas and artificial gas are two kinds of gas with different properties, and their calorific value, flame propagation speed, gas pressure and composition are all different. Natural gas is generally dry gas, the main component of methane, basically no impurities, high calorific value, slow flame propagation speed, high delivery pressure. The artificial production of coal gas is a mixture of gases, containing water, oil and dust, ammonia naphthalene, hydrogen sulfide and other impurities, lower delivery pressure.
Q:How many cubic gas is a gas tank?
The liquefied gas residual liquid, temperament also have some problems, but also easy to Duanjinqueliang, according to the user's actual reaction can be cheaper 2/3
Q:How much is the gas in the gas tank?
When the normal use of internal pressure (that is, pressure) 0.5 ~ ~ Pascal (combined with a force of 5 ~ 12 kg / cm2), the entire cross section to withstand the force of about 1000 kg
