Why copper components must not be used in the isolation devices for coke oven gas pipelines

Why must copper components not be used in the isolation devices for coke oven gas pipelines? For operational safety in gas areas, expensive copper wrenches should be used, but copper components are not allowed to be used in the gas pipeline isolation devices. Why? This is because gas contains components such as hydrogen sulfide and ammonia, which are corrosive to copper components. In particular, ammonia can form complexes with copper; this reaction occurs rapidly, and the resulting complex ions are soluble in water. Therefore, copper components cannot generally be used in such gas pipelines. In other words, since hydrogen sulfide, ammonia, and similar substances are corrosive to copper components and cause rust, it can lead to leaks in the sealing devices.
#A quick response here: #The main reason is that copper is a soft metal; when excessive force is applied, it can cause the product to deform, affecting its functionality, or in severe cases, it can lead to the failure of components such as threads, with extremely dangerous consequences. Therefore, as important safety components, steel structural elements are typically used.
