What is the minimum number of bolts required in a temporary bolted flange oil hose coupling?
AI Explanation
The correct answer is A) 4.
The minimum number of bolts required in a temporary bolted flange oil hose coupling is 4. This is based on the regulations in 46 CFR 56.30-30, which state that flanged joints must be secured with a sufficient number of bolts to prevent leakage. For a temporary flange connection, a minimum of 4 bolts is typically required to provide a secure and leak-proof seal.
The other options are incorrect because 6 bolts would be excessive for a temporary coupling, 3 bolts would not provide enough security, and a bolt in every hole would not be necessary for a temporary connection.
