Characteristics of working conditions
The newly developed oil and natural gas often contain a small amount of mixed gas such as H2S which will have certain corrosion on valve and pipeline materials and bring great safety risks when in humid environment. The common corrosion is stress cracking or hydrogen induced cracking.
Recommended valve selection

Considering these micro corrosive impurities, FBV recommends to use the materials conforming to NACE 0175 / ISO 15761 to manufacture valves, so as to eliminate the potential corrosion of valves caused by H2S and solve the worries of user FBV recommends ball valve, gate valve, globe valve, check valve and butterfly valve etc.
