fireproof material thermal insulation  for lng cryogenic storage

Flame-retardant cryogenic insulation paper(compatibility with oxygen) :

The flame-retardant cryogenic insulation paper is made of super-thin glass wool, which is produced in all -electrical kiln with blaze technology, by a peculiar manufactory process. The insulation paper is often composited with aluminum foil as a thermal insulation material for using in the vacuum jackets of storage and transportation vessels for cryogenic liquids(Liquid Hydrogen liquid oxygen, LNG, liquid Helium, liquid Nitrogen and liquid Argon).Its advantage are flame-retardant  at open fire and with the best thermal insulation characteristic(lower thermal conductivity, higher contact thermal resistance),low outgassing rate, light weight, high uniformity and wide range of the application temperature:-269°C-800°C

Q:Is natural gas solid?If so, under what conditions will become solid?
Combustible ice combustion equationCH4 8H2O+2O2=CO2+10H2O(reaction conditions for "light") [edit this paragraph] combustible ice found as early as 1778, the British chemist Pudesiteli began to study the gas generated by gas hydrate temperature and pressure. In 1934, people found the ice like solid blockage in oil and gas pipelines and processing equipment, which is not ice, which is now known as combustible ice. In 1965, Soviet scientists predicted that the gas hydrate may exist in the surface layer of the bottom of the ocean, and then finally found a large number of combustible ice on the Arctic seabed. In 1970s, the United States Geological drilling workers in the ocean, found a look like ordinary ice things, when it was pulled from the sea, the "ice" soon became a sparkling water, and those bubbles but accidentally lit, the gas bubble is methane. According to the study, these white ash, like dry ice, is a solid mixture of natural gas and water under high pressure and low temperature. The results of the present study show that it exists only in the submarine or the frozen soil zone. The appearance of pure natural gas hydrate is white, like ice and snow, it can be ignited directly like solid alcohol. Therefore, it is popularly known as combustible ice". [edit this paragraph] combustible ice causes combustible ice is gas molecules (alkanes) were water molecules in the crystal formation at the bottom of the sea temperature and under pressure. There are three basic conditions for the formation of combustible ice: temperature, pressure and raw materials. First of all, combustible ice can be generated above 0 degrees Celsius, but more than 20 degrees will decompose
Q:How much gas is equal to 1
In addition to the ideal gas, PV=nRT, if the pressure changes, we must know the temperature and pressure before and after the change, in order to know the volume change.Or is a m under 20MPa is fand how many liters in standard condition, which makes sense, can be seen from the above formula, the temperature under constant pressure is inversely proportional to the volume of the box.
Q:What's the difference between propane and gas?
The difference between propane and gas: propane is pure (only one gas), gas is a mixture of gases.
Q:0.3T gas steam boiler about one hour to burn a lot of natural gas
1 tons of boiler =60 kcal. 0.3T boiler =18 kcal,The calorific value of natural gas is about 8600 kcal, 0.3T gas steam boiler theory about an hour by 21 party gas, taking into account the actual utilization efficiency of boilers and boiler, steam boiler 0.3T gas per hour the actual gas should stand in 15-25.
Q:Is piped gas natural gas
The two are not the same as natural gas, more than and 90 per cent of all carbon 1 methane, methane content in coal gas natural gas is not so high
Q:What is the density of liquefied petroleum gas
The main component of alkane gas, including methane, majority, and small amounts of ethane, propane and butane, in addition there are hydrogen sulfide, carbon dioxide and nitrogen and water vapor and a small amount of carbon monoxide and trace rare gases, such as helium and argon.
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:What is the amount of heat contained in a natural gas
That is, the calorific value per cubic meter is equivalent to 9.3 to 9.88 degrees,3.83<1.07*9.3 OR 9.88
Q:The fire of the gas cooker turns red, the smoke is very big, and the bottom of the cooker is black
A good tune on the ignition switch is one of the intake valve is the intake valve ash is not sufficient to open the valve to open a small fire problem... We burn the gas stove on the site
Q:Why is the gas plant often mixed with a small amount of gas in the home gas (mainly carbon monoxide)
City homes can be installed gas alarm to prevent gas poisoningSo the answer is: it is convenient for people to find the gas leakage, close the gas valve, open the doors and windows, and install the gas alarm
