Bronze gate valve: leakage level list!

The leakage level of bronze gate valves is usually classified according to the provisions of API 598 [4]. This classification mainly distinguishes different leakage levels based on the size of the leakage, and sets different leakage levels according to the different media used. At the same time, the leakage level can be further divided into multiple categories, such as

Classification and application of leakage levels in each category
Since different industries have different requirements for leakage levels, there are specific leakage levels for different application scenarios. The highest level is Class I, which is suitable for places with extremely strict leakage requirements; Class II is used under normal working conditions; and Class III requirements are relatively loose.

The leakage level of bronze gate valves is very important, especially in fields such as oil production. Inappropriate leakage levels may lead to serious economic losses or even catastrophic consequences. For example, once an oil well gas leak occurs, it will not only directly lead to huge economic losses, but also cause serious environmental pollution problems.

In many ordinary factories, since the nature of the work is not particularly dangerous or important, a secondary or tertiary leakage level can be selected. This not only ensures the smooth progress of the work, but also saves a lot of money. Of course, this decision is based on the premise of guidance from professional experimental results.

To accurately understand the specific leakage degree of the valve, a series of scientific and rigorous test operations must be carried out on it (no further details are given here). First, a certain pressure must be applied to the valve to observe whether there is leakage, and then its sealing performance is judged based on the actual situation and the corresponding results are given. Another important step is to use a special method to detect whether the gas enters the pipeline in a closed state, that is, to conduct a sealing test. The above two methods will help you get the final answer!
