PURPOSE AND SCOPE
Selectors PrZh-02 are designed for sampling liquids from process pipelines under pressure. In particular, these devices can be used to sample water solutions of gases: ClO2; SO2 and others. In the PrZh-02-1 samplers, the welded branch pipe is made of titanium, and in PrZh-02-2 of stainless steel, Kh18N10T.
When sampling gas solutions using conventional ball valves, the sample is usually not reliable, because when the valve is opened, gas is rapidly released into the atmosphere. This leads to the fact that the content of dissolved gas in the sample entering the laboratory for analysis can significantly differ from the gas content in the liquid flowing in the pipe.In addition, the collection of aggressive media, especially from pressurized pipelines, often pose a risk to personnel.
Ambient temperature, deg. C -0 - + 50;
Atmospheric pressure, kPA -84 - 106.7;
Relative humidity at a temperature of +25 degrees. C,% - up to 100.
Selectors PrZh-02 are permanently installed on pipelines and allow sampling of a given volume, practically without loss of the gas dissolved in it.
Sampling is safe, as the laboratory capacity is filled in the sampler during filling, that is, the lab technician does not keep it in hand. In addition, when filling the vessel, the pressure in the sample is equal to atmospheric pressure and the possibility of splashing is excluded. Samplers are made of corrosion-resistant materials (titanium, fluoroplastic), which allows them to be used for almost all liquid media.
