摘要： A fluid communication nipple including a tubular mandrel having an interior surface defining an internal bore and a passageway extending substantially lengthwise along a portion of the mandrel. The passageway is defined by an exterior wall section and an interior wall section, wherein the interior wall section extends outward from the interior surface into the bore. When it is desired to establish fluid communication through the passageway between the exterior and interior of the nipple an opening is formed through the internal wall section.
