What Is Dead Leg And Explain?

1.	What Is Dead Leg And Explain?
Answer» Dead LEGS: Piping sections that are potential for internal corrosion due to flow STAGNATION. Dead legs are CREATED mainly by flow stagnation enhanced with presence of settled water and solid deposits. When the length of the section or branch , for 2 inch pipes and larger, is longer than three times its pipe diameter, or 1.22 m (4 ft) in length, the length of the dead leg is the distance measured from the outside diameter of the header (or RUN) to the near end of the branch valve. For branch connections of 1-½ inch NPS and smaller, the length of the dead leg is the distance measured from the end of the BOSS to the near end of the valve.
