Gasket seal leakage simple treatment method
Gasket seal leakage simple treatment method
Leakage between flanges is common, and fast and accurate elimination and treatment methods are very critical: 1.After the leak is found, tighten the bolt first. First tighten the bolt that can see the leak end or the flange gap is large, and then tighten the other bolts diagonally. 2.If the leakage cannot be eliminated in the previous step, loosen all bolts on the flange, check the gasket, and then pre-tighten the bolt diagonally and observe the flange clearance. After confirming that it is normal,    &

Gasket seal design requirements
Leakage rate: The amount of sealed fluid that leaks through the volume or mass of the connecting surface per unit time. The US PVRC is classified into five seal grades according to the quality leakage rate Seal grade Mass leakage rate  mg/(s mm)   Application situation T1 (economy) ≤2×10^-1 Public（water、air） works T2 (standard） ≤2×10^-3 General requirements T3(compactness) ≤2×10^-5

Nuclear radiation
Universality： The number of sealing points in process industrial devices is very large. For example, there are more than 1.23 million static sealing points in 5 sets of main devices, 6 sets of supporting devices and 7 auxiliary workshops with an annual output of 300,000 tons of ethylene. Leakage is the main cause of various accidents in chemical or petrochemical enterprises. Perniciousness： Petrochemical and chemical processing fluid for most flammable, explosive, toxic or corrosive media, plus pressure and temp
