Sulfur hexafluoride gas introduces the application fields of sulfur hexafluoride

Sulfur hexafluoride gas is a colorless, odorless, non-toxic and non-corrosive compound. At normal temperature, it is a gas, a non-flammable body, and a non-metallic oxide with good chemical stability. Because sulfur hexafluoride gas has excellent chemical thermal stability, it will not be decomposed at 500 degrees temperature under the condition of ensuring purity. Due to its excellent insulation and arc reduction ability, even if the instantaneous decomposition and ionization occur under the arc, it can quickly return to the original stable state after the arc reduction, so it makes use of its high chemical stability and excellent electrical insulation characteristics, and widely uses the electrical industry and ultra-high voltage insulation materials. In addition, it has the characteristics of large heat transfer coefficient and good cooling effect.

Sulfur hexafluoride gas is widely used in high pressure, medium pressure electrical equipment insulation materials and arc reduction medium; Anti-oxidants for metal smelting and manufacturing processes, meteorological tracer experiments and tracers, refrigerants and heat carriers for refrigeration processes. An insulator used in medical applications for X-ray devices. It can also be used for manufacturing monocrystalline silicon and basic theoretical scientific research.

GIS, SF6 circuit breakers, SF6 transformers and other equipment will be filled with a certain pressure (density) of SF6 gas, the pressure unit used in the domestic industry is Mpa, and many European, Japanese joint venture manufacturers often use bar and psi and other gas pressure units, which will cause some trouble to everyone. Here Weavers Xiaobian collection of several units of conversion formulas for your reference.

In engineering, megapascals (MPa) are commonly used: 1MPa=1,000,000Pa.

A standard atmospheric pressure =1.00336×0.098MPa= 0.1010mpa ≈0.1Mpa.

1 bar = 0.1 MPa

The legal unit of pressure is the PASCAL (Pa) : 1Pa=1N/㎡ (Newtons/square meter).

Pressure unit conversion:

1MPa=1000kPa， 1kPa=10mbar=101.9716 mmH2O = 4.01463imH2O

10mWC = 1bar = 100kPa, bar = 0.987 atmospheres = 1.02 kg/cm2 = 100 kpa = 14.5 psi

1psi=6.895kPa=0.06895bar, 1 MPa =145 LBS/inch2 (psi)=10.2 kg/cm2 (kg/cm2) =10 bar (bar)=9.8 atmospheres (atm)

1 lb/inch 2(psi)=0.006895 MPa =0.0703 kg/cm2 (kg/cm2) =0.0689 bar (bar)=0.068 atmospheric pressure (atm)

1 bar (bar)=0.1 MPa =14.503 LBS/inch2 (psi)=1.0197 kg/cm2 (kg/cm2) =0.987 atmospheres (atm)

1 atmosphere (atm)=0.101325 MPa =14.696 LBS/inch2 (psi)=1.0333 kg/cm2 (kg/cm2) =1.0133 bar (bar)

Note: PSI is called Pounds per square inch. P is pound pound, S is square square, I is inch inch. Convert all units into metric units and you can calculate: 1bar≈14.5psi, psi is often used in Europe and the United States
