Pressure Pound Class in Valve FittingsLband kg,MPaconversion table
, with the continuous integration of China's economy and the world economy, some basic units are also in line with the world, and the pound level in the pressure basic unitLbis one of the typical, engaged in the valve fittings work friends experience more profound, it is widely used in the country kg,MPa?
Pressure Unit Pound ClassLbis a U. S.-based American pressure base unit, which often appears in valve fittings.150Lb,300Lb,600Lb,900Lband other pressure labels, its domestic use of kilograms,MPacorresponding conversion table is as follows:

Through the above table, we can quickly convert the domestic pressure level corresponding to the pound-level pressure, and then accurately select it according to the actual working pressure, or convert it through simple digital division, specifically following the following two rules:
1.150LbconvertedMpa, the pound seriesLbdivided75, such150Lbis2.0Mpa;
2,300LbconvertedMpa, the pound series Lbdivided60, such as 600LbNominal pressure is10.0Mpa;
