When industrial plant equipment items are overpressured, the is an essential safety device that automatically releases gases and sometimes liquids. Those pressure relief valves are required by industrial design codes and standards as well as by law. The released gases and liquids are routed through large systems called flare headers to a vertical elevated flare. The released gases are as they exit the flare stacks. The size and. Flare line means a line used to carry gas away from the rig to be burned at a safer location. The gas comes from the degasser, gas buster, separator, or when drill stem testing, directly from the drill pipe. Functionally operated means activating equipment without subjecting it to well-bore pressure.
[pdf] In a drilling rig, the drill line is a multi-thread, twisted wire rope that is threaded or reeved through in typically 6 to 12 parts between the traveling block and crown block to facilitate the lowering and lifting of the drill string into and out of the wellbore.
